1 INTRODUCTION

1.1 Document purposeThis manual will help you understand the operation of stand-alone generation systems and will provide you with the necessary guidelines for correct installation, adequate use and good maintenance of the equipment forming part of a stand-alone system.

It is extremely important that you read and understand all the information and instructions contained in this manual before commencing the equipment installation work.

1.2 Stand-alone systemsA system based on the Ingecon® Hybrid MS is intended to provide those locations that have no access to the conventional electricity grid with electric power of similar characteristics to that provided by the grid. However, a stand-alone system will never have the energy capacity of a conventional distribution network, and this factor should be taken into account when designing the installation.

This equipment is ideal for replacing a diesel generator based system with one which combines a diesel generator with renewable energy sources.

This type of installation is made up of the following equipment:

- Renewable energy generating sources (PV panels, wind turbines…)

- Backup energy generators (genset)

- Accumulation equipment (batteries)

- Associated power converters

Astudyofthesite,renewableresourcesandchargeprofilesshouldfirstbeconductedinorder to determine the most adequate equipment for each particular installation.

1.3 INGECON® HYBRID MS - General descriptionThe Ingecon® Hybrid MS units have been designed for the off-grid generation of pure sine wave three phase electrical power based on renewable energy sources, using batteries as a means of accumulation. Furthermore, the Ingecon® Hybrid MS units can be connected to a backup generator for a guaranteed electricity supply at all times.



This is a modular system that can be adapted to suit the requirements of each parti-cular installation. The installer is therefore responsible for optimizing the design and configuration.

A number of power converter modules are available and can be combined to suit the specificinstallationrequirements.Eachmoduleismadeupofan«electronicsblock»,and the switchgear and power devices required by each converter.

An installation shall at least have a battery charger module and an inverter module. A maximum of four modules of each type can be installed.

Battery charger moduleThis module is responsible for managing the battery bank charging and discharging. An installation must have at least one main battery charger module and, optionally, up to three secondary modules.

The main battery charger module is essential for any installation, as it controls communications with the other modules, supervises the status of all inputs and manages the permissions to operate. This module also includes the user interface display.

The main module is also equipped with a 15kW MPPT PV input.

Inverter moduleThis module generates a pure sine wave three phase voltage, with constant amplitude and frequency, adapting the output power to that demanded by the installation loads.

When the backup generator is operating and connected to the loads, this module canoperateasarectifiertorechargethebatteries.

The installation power can be increased by connecting up to a total of four inverter modules in parallel.

Photovoltaic moduleThis module manages three 15 kW PV inputs, with an independent MPPT control. Theseinputscanbeconfiguredtooperateinparallel,therebyobtainingasingleinput with a maximum power of 45 kW.

To increase the power of the installation, up to four modules can be mounted in the same system

Wind turbine moduleA converter to manage three 15 kW wind power inputs with an independent MPPTcontrol.Theseinputscanbeconfiguredtooperateinparallelwithtwooptions:

- The three inputs in parallel forming a single input with a maximum power of 45 kW

- Inputs 1 and 2 in parallel forming a 30 kW input and a 3rd independent input of 15 kW.

In addition, the wind power module can incorporate a dump load system.



To increase the installation power, up to four modules can be mounted in the same system.

The installation shall be completed with other external devices, dimensioned in accordancewiththeoverallpowerandconfigurationandwhichcanoptionallybe supplied by INGETEAM ENERGY S.A.

Examples include:

-Breakerforthebatteryfield

- Kit for the backup genset

- AC protections for persons and loads connected.

- Galvanic isolation transformer

- Battery temperature sensor (a product manufactured by INGETEAM ENERGY S.A.)

- Backup generator power meter (a product manufactured by INGETEAM ENERGY S.A.)

1.4 Operating principleThe Ingecon® Hybrid MS is basically designed to generate AC voltage from renewable energy sources. The battery charge / discharge status and the backup generator con-nection / disconnection will depend on the energy generated by the renewable sources and the demand made by the installation loads.

Priority shall always be given to energy extraction from the renewable sources through the use of maximum power point tracking methods.

When the energy available is greater than demand, the surplus energy shall be stored inthebatteries.Oncethebatterybankisfullycharged,itshallbemaintainedinfloatstatus and the power generated shall be adjusted to meet the demand.

On the contrary, when the connected load requires more energy than that generated by the renewable power source, then the system shall absorb the required energy from the battery bank. The time during which this status can be maintained shall depend on the battery charge status and capacity. For this reason, when dimensioning the battery bank capacity, account should be taken of the required autonomy of the installation during those periods in which the renewable sources are not operating.

If the installation needs to provide an uninterrupted power supply, then a backup power source will be necessary, such as a diesel generator. Furthermore, this backup power source is recommended in order to guarantee the supply at times of high consumption (this facility requires a wattmeter).

The connection of the backup generator can occur for different reasons, all of which are configurable(chapter14.3):

·Timesetting.Aperiodoftimefordailyconnectionscanbeconfigured.

· Battery low charge status, to prevent the battery bank from over-discharging.

· High consumption (the INGETEAM ENERGY S.A. wattmeter is required).

· Battery equalisation. To ensure that the equalisation cycle is completed correctly.

· Manually, by a user-given order.



When the backup generator is connected, this directly feeds the loads. The Ingecon® Hybrid MS behaves like yet another load, rectifying the voltage in order to charge the batteries.Thebatterychargepowerfromthebackupgeneratorisconfigurablefromzeroup to the Ingecon® Hybrid MS rated power.

We would recommend having a backup generator power that is double that of the equi-pment power in order to guarantee that consumption is supplied and the batteries are charged at the same time.

With the backup generator connected, all the energy available from the renewable sources shall be used to charge the batteries.

1.5 LocationTheIngecon®HybridMSunitsneedtobelocatedinenvironmentswithsomespecificcharacteristics.

This section provides guidelines on selecting and correctly adapting the equipment to a suitable site.

Environment

Locate the units in a place which is easily accessible for installation and maintenan-ce work, with room to operate the keyboard and to read the front LED indicators.

It is forbidden to leave any object on the equipment.

Air outlets and those parts of the cabinet close to the outlets can reach tempera-tures of 85 ºC. Do not place any heat-sensitive material in the vicinity.

Avoid corrosive environments.

The room or enclosure in which the battery bank is installed must be compliant with the safety regulations in force in the particular region or country. For Europe, the corresponding standard is EN 50272-2 and its adaptations to each member state.

The enclosure in which the Ingecon® Hybrid MS unit is installed must incorporate a safety system to restrict access solely to authorised personnel.

IP Rating

The Ingecon® Hybrid MS units have a protection rating against external agents of IP20.

IP20 means that the equipment is protected against the ingress of foreign bodies andagainstfreeaccesstodangerousparts,asdefinedforthisprotectionratingin the IEC60529 standard

.Therefore:

The Ingecon® Hybrid MS must be installed in a covered enclosure.The equipment environment must always be dry and free from dust.It is not suitable for outdoor installation.



Ambient temperature

The Ingecon® Hybrid MS units are designed to operate between –10ºC and +40ºC.

Atmospheric conditions

The surrounding air must be clean and the relative humidity must not exceed 50% at more than 40 ºC. Higher percentages of relative humidity, up to 95%, are tolerable at temperature below 30 ºC.

Account should be taken of the fact that, occasionally, moderate condensation may occur as a result of temperature variations. For this reason, in addition to the unit’s own protection system, the equipment should also be monitored when operating at sites which may not come within the atmospheric conditions described above.

Contamination rating

The units have been designed for a grade 3 contamination rating.

Appropriate measures should be taken to locate the equipment in an environment with dust-free, good quality air.

Noise contamination

When operating, the Ingecon® Hybrid MS makes a slight buzzing noise.

Do not locate the units in an occupied room or on lightweight supports which amplify this buzzing noise. The mounting surface must be firm and adequate for the weight of the equipment.

Mounting

The modules have been designed to be stack mounted up to 4 modules high, in stacks of either the same or different types of modules. To facilitate interconnection, modules of the same type should be stacked together.

The mechanical and electrical connections are explained in detail in chapter 9.

Themodulesmustbeinstalledasdeliveredfromthefactory.Anymodificationintheir structure will void the warranty and could also create a risk of malfunction.

Ventilation

For ventilation reasons, there has to be at least 800 mm clearance around each stack. Installer should notice that it is a minimun clearance that we recommend to increase for ease of maintenance.

Air should be allowed to circulate freely in order to ventilate the equipment.

2 BATTERY CHARGER MODULE

2.1 Details of the moduleThis module controls the charging and discharging of the battery bank, protecting it from overcharges and from deep discharges.

A distinction is made between the main battery charger module and the secondary battery charger module (up to three per installation).

The main battery charger module is essential in any installation, given the fact that it controls communications with the other modules, supervises the status of all the inputs and manages the permissions to operate.

The main battery charger module is also equipped with a 15 kW photovoltaic input with MPPTandtheuserinterfacedisplay,whichservestomodifytheconfigurationandmonitorthe key data for the installation.

Based on the characteristics provided by the battery manufacturer, all the battery parameterscanbeconfiguredtooptimisethemulti-stagechargingprocess(Chapter14.2).

2.2 Technical SpecificationsBattery charger

• Maximum power: 30 kW

• Voltage range: 240 to 500 Vdc

• Maximum current: 100 Adc

•

Photovoltaic input (only in main module)

• Maximum power: 15 kW

• Voltage range: 150 to 700 Vdc

• Maximum current: 30 Adc

The battery charger voltage range refers to absolute values. Account should be taken of the fact that the battery charge voltage is higher than its rated voltage. The battery bank should be dimensioned to ensure that all the charge voltages required are within the range indicated.

The charge voltage depends on the type of battery and shall be established by each manufacturer. However, as a general rule, the process to charge a lead-acid battery bank with a rated voltage of 450 V requires a voltage that is considerably more than 500 V which would be exceeding the upper range limit.

The charger module limits the power to 30 kW and the battery current to 100 A. This implies that, for example, with a battery voltage of 330 V, the maximum battery current would be 90 A (limit of 30 kW); but also that with a voltage of 240 V the maximum power would be 24 kW, as the current is limited to 100 A.

When modules are connected in parallel, the power and current limits are multiplied by the number of modules, however the voltage range does not vary.



3 INVERTER MODULE

3.1 Module detailsThe inverter module is a two-way converter that will function as:

• An inverter, generating a pure sinewave three phase voltagewith a constantamplitude and frequency, when operating without the backup generator.

• Asarectifier,chargingthebatteries,whenthebackupgeneratorisfunctioningandpowering the loads.

• Assupportforthebackupgenerator,ifthisisoperating,thebatteriesarechargedand renewable energy is available.

There is a distinction between the main inverter module (one per installation) and the secondary inverter module (up to three per installation). In general, each inverter module is shipped from factory as a main inverter module. On installation, the internal cabling must be modified to allow it to operate as a secondary inverter module. (See the sectionon«Internalconnexioninsecondarymodules»).

3.2 Technical specifications• Rated power: 30 kVA (10kVA per phase)

• Voltage: 380 to 430 Vac (three phases plus neutral).

• Frequency: 50-60 Hz

• THD <4

• Cos(φ):-1to1

• AC output short-circuitable

• Accessible isolated neutral. If the installation requires the neutral to be earthed, a galvanic isolation transformer module should be installed (Chapter 8.3)

• Supports charge imbalances. The maximum power per phase is 10kVA.

4 PHOTOVOLTAIC MODULE

4.1 Module detailsThe module comprises three 15 kW PV inputs.

Each PV input incorporates an algorithm for tracking the maximum power (MPPT) and another to adjust the power to demand. The algorithm in use will depend on the system conditions at each particular time.

It is important to correctly dimension the PV arrays in order to avoid limiting the input power by exceeding the maximum current.

Thethreeinputscanbeconfiguredas:

- three independent inputs

- Three inputs in parallel, performing like a single input with a maximum power of 45 kW (90 Adc).

5.1 Module detailsThe module comprises three independent wind power inputs.

Each input incorporates an algorithm for tracking the maximum power (MPPT) and another to adjust the power to the demand. The algorithm in use will depend on the system conditions at each particular time.

It is important to select the right wind turbines in order to avoid limiting the input power by exceeding the maximum current.

Thethreeinputscanbeconfiguresas:

6 DUMP LOAD

6.1 Key characteristicsThe dump load system is a wind power module accessory designed to brake the wind turbines in order to adjust the power generated to that demanded by the installation, maintaining control over the same.

It comprises three resistor units, one for each wind power input of 15kW.

7 GENSET

7.1 Key characteristicsThe backup generator is responsible for creating the three phase voltage electrical network, whenever it is operating and coupled to the Ingecon® Hybrid MS. This implies thatitshouldhavesufficientpowercapacitytoindependentlymeetthetotaldemandofthe loads.

Wind Power input configuration



Furthermore, it is advisable to dimension the generator so that it can be used to charge the batteries at the same time. We would therefore recommend having a backup generator with a rated power that is double that of the rated power of the installation.

For reasons of maintenance and guarantee of supply, an installation can be equipped with up to four generator units connected in parallel. In this case, switching between the generators or, where applicable, synchronisation, is not controlled by the Ingecon® HybridMSandthesysteminstallerisresponsibleforselectingthespecificcontrollertoperform this task. (Chapter 14.3).

Ingecon® Hybrid MS modules don’t include the necessary elements for connection of back up generator. Genset kit has to be acquired.

8 OTHER DEVICES

8.1 Genset kit The kit for the backup genset comprises the following:

- Contactor for the connection of the backup generator

- Thermal magnetic breaker to protect the generator

- Terminal connection strip

- Energy meter (wattmeter)

- Current measurement transformers

- Thermal magnetic breaker for the AC output of the Ingecon Hybrid MS (in Kits for backup gensets of 120kVA, 180kVA or 240kVA).

There are four models, depending on the backup generator rated power:

1- Kit for a 60kVA genset




Note: We would recommend a backup genset power rating that is double that of the inverter modules installed. If the backup genset power rating is greater than the recommended one, this should be taken into account in the kit design.



8.2 Protection devicesSome electrical protection devices are included as standard in the Ingecon® Hybrid MS system modules The installation can then be completed with other protection devices:

• Battery bank breaker (mandatory). A breaker to disconnect the battery bank must be installed. It must be dimensioned in accordance with the number of battery charger modules.

• Differential protection. Consult the legal requirements in force in the region in question.

• AC voltage surge arrestor (recommended).

• General thermal magnetic breaker (recommended). In an installation with more than one inverter module, we would recommend including a general breaker to provide a single disconnection point for the AC output. The backup genset kit (chapter 8.1) includes this breaker.

8.3 Galvanic isolation transformer moduleFor safety reasons, it is always recommendable to install a galvanic isolation transformer, which, depending on the legislation in force, may be mandatory.

Should it be necessary to earth the installation neutral, the galvanic isolation transformer is essential for the correct operation of the Ingecon® Hybrid MS. The primary neutral (Ingecon output) must never be earthed.

The galvanic isolation transformer module comprises three single phase transformers with a ratio of 270:270 and a rated power based on the number of inverter modules.

9 INSTALLATIONPlease read these instructions carefully before installing the Ingecon® Hybrid MS.

The modules are heavy and cannot be handled by one person. To avoid personal injury, use the appropriate transport and lifting equipment.

Use the connections available. Do not drill or modify the module ports.

The Ingecon® Hybrid MS modules are designed to be stacked up to 4 modules high.

We would recommend stacking modules of the same type together to facilitate interconnection.

The bottom modules shall be equipped with a base.

Once the installation work has been completed, mount the bus bar cover. Inadvertent contact with any of the bus bars represents a serious risk of electrocution, even if the equipment is not operating

.

9.1 Module assemblyThe vertically stacked modules are assembled with the aid of threaded rods. Once the lower module has been positioned, four rods are inserted (see photo).

Module assembly



Then the next module shall be coupled to it. The two rods at the rear are used as a guide. The two front rods serve as an earth between the modules (chapter 9.9) and shall be firmlysecuredwiththeaidofanut.

9.2 Electrical connection The electrical connections between the modules are made at the rear

• Power connections: By connecting the copper bars.

The number of bars to be connected depends on the module in question.

Thefirst threebarsconstitute thepowerconnectionbetween themodulesandmustbe interconnected one by one (vertically), connecting all the modules in the installation

To connect bars in the same stack, the connecting bars supplied with the equipment shall be used.

Bars from different stacks shall be connected by external cabling.

We recommend wires that can support 200 A.

Securing the modules

Connection of a Battery charger module with an Inverter Module



If there are various battery charger modules in an installation, then the remaining bars must also be interconnected one by one (vertically).

Connection of two Battery Charger Modules

If there are various inverter modules in an installation, then the remaining bars must also be interconnected one by one.

9.3 Internal connections for the secondary modulesIn an installation with more than one charger module, one will be the main module and the others will be secondary modules.

In an installation with more than one inverter module, one will be the main module and the others will be secondary modules.

Some of the differences between a main module and secondary module are based on the internalconnectionofthereferencesignals(JR1andJR2cables)andthepermissionssignals(JPcable).

Withregardtothechargermodule,themainmoduleisclearlyidentifiedbythefactthatit is the one containing the display. The others are secondary modules. The internal cablingofJR1,JR2andJPisadaptedduringthemanufacturingprocessand,therefore,nomodificationisrequiredforstart-up.

However, this section should be taken into account when replacing the electronics block. All electronics blocks supplied as spares are manufactured to be directly mounted in themainchargermodule.Specifiedbelowaretheconnectionsformountinginamainmodule and also those for mounting in a secondary module.

With regard to the inverter module, the main module differs from the secondary one in thecablingofJR1,JR2,JP.Generallyspeaking,allinvertermodulesaremanufacturedasmaininvertermodules,and,therefore,needtobemodifiediftheyaretofunctionasa secondary inverter module.

Note: Exceptionally, a main inverter module can be converted to a secondary module at the factory. The installer must examine the internal cabling to identify each module.

Warning: Two Main Inverter Modules cannot coexist in the same installation.

This section should be taken into account during commissioning or after extending the installation and in any work to replace the inverter module or electronics block. The differences between the connections for the main inverter module and secondary module are explained below.

9.4 Connection of the battery bank

The battery charger Ingecon® Hybrid MS modules do not include cut-off and protection switchgear for the battery bank. The installer must provide for these devices, in compliance with the regulations in force in the region in question.

When making the connections, the cabling should be voltage free.

The battery bank shall be connected to the connections bus bar, located on the rear of any of the battery charger modules. Cable access is through the ports in either the top or bottom bus bar covers.

The connection shall be made with an M12 ring terminal.

Make the connection paying particular attention to maintain the security clearance between live parts and the enclosure.

Pay particular attention to the polarity. The equipment will be seriously damaged by cables connected with reverse polarity.

9.5 Connection of the AC lineThe cables making up the distribution line are connected to the connections bus bar, on the rear of any of the inverter modules.

The cable access is through the ports in the upper or lower bus bar covers.

The connection is made with an M12 ring terminal.

Make the connection paying particular attention to maintain the security clearance between live parts and the enclosure.

9.6 PV array connection

Never forget that, whenever the panels are exposed to light, voltage is generated at the PV panel terminals. Therefore, whilst connected to the PV array, the equipment may hold extremely hazardous voltages.

Always make the connection with the breakers open.

Pay particular attention to polarity. Connecting the cables with the wrong polarity could seriously damage the equipment.

The PV arrays are connected at the terminals at the rear of the corresponding module

Rated section 16mm2.

Maximum section 25mm2.

Should it be necessary to use a greater cable section, then we would recommend using an external distribution box located close to the equipment in order to make the section change, so that the section is suitable for the one tolerated by the equipment.

14.2 BATTERY OPERATIONBattery longevity depends on many factors, the most important being the charge and discharge levels the battery is subjected to, the number of cycles, the cycle temperature, etc. It is therefore exceedingly important to be acquainted with the parameters of the batteries used and the installation operating characteristics.

An Ingecon® Hybrid MS unit executes the charge and discharge cycles according to the parametersconfigured.Theinstallerandheadofmaintenancearethereforeresponsibleforensuringthatthesaidconfigurationisappropriateandthattheenvironmentalconditionsare maintained within the recommended parameters, to avoid damage to the battery and to prevent premature ageing.

- High temperatures accelerate the chemical processes, reducing the battery life.

- High charge voltages lead to the corrosion of the positive pole.

- Low charge currents and long periods with no complete charge, create sulphates on the electrolyte.

- Rapid, incomplete charges can lead to cell imbalance.

-Ifthefloatvoltageistoohigh,itwillcausealossofelectrolyte.

- Long equalization cycles performed at a high temperature will lead to a loss of electrolyte.

In any case, you are recommended to carefully read the manual for the batteries in the installation and consult the battery manufacturer about any doubts you may have.

The Ingecon® Hybrid MS units are equipped with a multi-stage battery charger. This term refers to the different stages of the charging process: a constant current stage; a constantvoltageorabsorptionstage;andafloatchargestage.Thereisadditionallytheoption of an equalization charge stage.

Charge modes:

- Constant current charge. A constant charge current is applied until the battery reaches the absorption voltage value. The current will depend on the battery characteristics and the desired charge speed. It typically varies between C/10 and 2C.

Signal requirements

During the back-up generator connection and operating process, a number of signals need to be sent and monitored, and these must be correctly wired (see the section on the back-up generator wiring).

- Order to start / stop the back-up generator. The main battery charger module shall enable the order for the remote start-up / shut-down of the back-up generator. For this purpose, there is a normally open (NO) potential free contact available and a normally closed (NC) potential free contact, in order to suit the requirements of each specificinstallation.

- Back-up generator voltage capture. The inverter module must read the voltage of the back-up generator (L1, L2, L3, N) in order to perform the correct synchronisation at the time of connection and supervise the subsequent operation.

AC consumption

14.3 GENSET Connection and operating modesThe Ingecon® Hybrid MS has an input to connect a back-up generator in order to guarantee supply at peak times or during renewable energy low production periods.

Note: the back-up generator can be any machine that generates a three phase voltage of an amplitude and frequency that is equal to that generated by the inverter. The conventional electricity grid can be connected as a back-up generator, although the equipment will not deliver power to the grid.

WARNING. During the connection with the back-up generator, the Ingecon Hybrid neutral must be prevented from being earthed. In such a case, a galvanic isolation transformer should be installed, to isolate the equipment neutral from the rest of the installation.

Although the Ingecon® Hybrid MS modules are designed to manage the back-up generator, external devices need to be installed for the power connection (Back-up Generator kit). These devices shall be dimensioned to suit the rated power of the installation and that of the back-up generator. They can either be supplied by INGETEAM ENERGY S.A. (chapter 8.1) or by the installer.

A four pole thermal magnetic breaker (IAM) is required to protect the back-up generator, a three pole contactor (KM1) with a normally open (NO) auxiliary contact and a terminal strip for the necessary connections.



- Signal for the closure of the power contactor. When the voltage generated by the Ingecon® Hybrid MS is synchronised with that generated by the back-up generator, the inverter module enables a signal for the closure of the power contactor. This is a NO contact which should be wired to ensure that, when enabled, the contactor coil is powered at its rated voltage.

- Contactor closure signal. The power contactor to connect the back-up generator must have a NO auxiliary contact which, when wired to the inverter module, will indicate that the contactor has closed.

Operating sequence

The connection and disconnection of the back-up generator shall be performed as a result of the evaluation of a number of criteria which will be explained in detail in the next section.

If the connection of the back-up generator is required, then the main battery charger module shall enable the start-up signal.

From that moment onwards the Ingecon® Hybrid MS shall monitor the voltage generated by the back-up generator, waiting for it to comply with the established amplitude and frequency ranges (190V<Vrms<260V; rated FR ±5Hz).

Once the voltage read is correct and is held stable for 1 second, the process to synchronise the voltage generated by the Ingecon® Hybrid MS with that generated by the back-up generator shall be initiated. In other words, the Ingecon® Hybrid MS shall start to generate a voltage of the same amplitude, frequency and with the same phase as that of the back-up generator.

Once synchronised, the Ingecon® Hybrid MS gives the order to close the power contactor, and awaits the signal to indicate that this closure has been made.

Once the connection signal has been received from the contactor, the Ingecon® Hybrid MS inverter moves to a secondary level, and the loads are powered directly by the back-up generator.

Thesubsequentoperationwillonceagaindependontheconfigurationofeachinstallation:

- With a battery charging power equal to zero (parameter 406), the Ingecon® Hybrid MS will monitor the voltage generated by the back-up generator but will not manage it and will practically play no part in the AC side of the installation. It will only retake control of the AC voltage if it detects a fault in the back-up generator before the order to disconnect is given. In this status, all the power from the renewable sources shall be used to charge the batteries.

- With a battery charging power other than zero (parameter 406), the Ingecon® Hybrid MSshallfunctionlikeaback-upgeneratorload,andshallgointotherectifiermodeinordertochargethebatterieswiththepowerconfigured.Inthisstatus,thepowerfromthe renewable energy sources shall also be used to charge the batteries.

Clarification.Theconfiguredchargingpowerisactuallytheback-upgeneratormaximumbattery charging power limit. The maximum battery charging power shall be limited bythechargingcurrentconfigured(parameter002),whichmustneverbeexceeded.Account should be taken of the fact that part of this current will come from the renewable energies and the rest will be taken from the back-up generator (value of parameter 406 asamaximumvalue).Thegeneratorchargingpowershouldbeconfiguredtoensurethat, in a situation of maximum consumption at the installation, the back-up generator is not overloaded.

To avoid supply problems, it is advisable to have a back-up generator power rating that is double the equipment power rating.



When the back-up generator is to be disconnected, the Ingecon® Hybrid MS orders the contactor to open, and undertakes the AC voltage generation and powers consumption. Subsequently, the order to shut-down the generator will be given.

Connection criteria

Theconnectionanddisconnectioncriteriafortheback-upgeneratorareeasilyconfigurable.Anyqualifiedpersoncanmodifythemtosuittherequirementsofaparticularinstallation.

Connection criteria:

• Manual start-up

• Time setting

• Battery state of charge

• High consumption (only with the INGETEAM ENERGY S.A. wattmeter)

• Battery equalization

Note: It will not be possible to connect the back-up generator through the Ingecon® Hybrid MS if the latter is in error status. In order to be able to connect the back-up generator, the Ingecon® Hybrid MS must be correctly generating AC voltage. In the event of an Ingecon® Hybrid MS error, the back-up generator must be started manually and connected to the loads through a bypass contactor.

Manual start-up

(Menu Extras/ Back-up start-up)

This parameter can be used to give a manual order to start-up the back-up generator, regardless of other criteria.

The generator will remain on until the manual start-up is disabled from this same screen (it will only disconnect if there are no other criteria requiring it to be connected).

Time setting

(Parameters 409-410, 411-412, 413-414)

The back-up generator can be connected for a set time. The times set shall be maintained for all the days of the week and can be changed at any moment. This functionality guarantees, on a daily basis, a minimum battery charge and / or can serve to supply loads at peak consumption times.

Parameters 409 and 410: back-up generator start-up time.

Parameters 411 and 412: back-up generator disconnection time. If, at this time, the batterystateofchargeisbelowthestateofchargeconfiguredforparameter408,thentheback-upgeneratorshallremainconnecteduntilthedefiniteshut-downtime(parameters413 and 414).

Battery state of charge

(Parameters 407, 408)

The back-up generator shall always start-up when the battery state of charge is below a configuredvalue(parameter407),therebyprotectingthebatteriesfromdeepdischarges.

Thegeneratorwillremainonuntilthebatterystateofchargereachesthelevelconfiguredwith parameter 408.

High consumption

(Parameters 416, 417, 418, 419)

Important note: To be able to start-up the back-up generator due to high consumption, the installation needs to be equipped with the INGETEAM ENERGY S.A. wattmeter in order to measure the power generated by the back-up generator.

If the installation is equipped with the INGETEAM ENERGY S.A. wattmeter (optional component) then the order can be given to start-up the back-up generator at times of high consumption, thereby mitigating the effect of consumption peaks on the battery bank or in order to supply loads that are greater than the equipment rated power. In this latter case, the back-up generator must be dimensioned to supply the loads.

The wattmeter is a device which measures the power delivered by the back-up generator when connected, giving information on the installation power consumption at all times.

In general terms, the back-up generator will start-up if the consumption is high (higher thanaconfigurablevalue),andwillremainonforaminimumtimeof10minutesandwillthenshut-downwhenconsumptionislowerthananotherconfigurablevalue.

There are two ways to connect the back-up generator for high consumption:

- Instantaneous connection. The connection is made if an instantaneous consumption greater than the value of parameter 416 is detected. If required, this connection can be configuredtobemadeonlyifthesaidconsumptionismaintainedforatimeperiodwhichisconfigurablethroughparameter417.

- 60 second timed connection. The connection will be made if a consumption greater than the value of parameter 418 is detected for one minute.

Anumberofparametersmustbeconfigured:

Parameter 416: Value of the current, above which the back-up generator will start-up due to high consumption. This parameter is given as a percentage and is applied to the inverter ratedcurrentandtothebatterydischargecurrent.Ifduringaspecifictime(parameter417) the inverter AC current exceeds this % of its rated current in any of the phases or thebatterycurrentexceedsthis%ofthevalueconfiguredasthemaximumdischargecurrent (parameter 003), the order shall be given to connect the back-up generator.

Parameter 417: Connection dwell time. This is the time during which the inverter or battery current must remain above the value of parameter 416 in order to order the connection of the back-up generator. This must be programmed taking into account the start-up peaks required for motors and similar machinery in order to avoid the undesired connection of the back-up generator in this situation.

Parameter 418: Value of the current above which the back-up generator is connected due to high consumption. This parameter is given as a percentage and is applied to the inverter rated current and to the battery discharge current. If during one minute the inverter AC current exceeds this % of its rated current in any of the phases or the battery currentexceedsthis%ofthevalueconfiguredasthemaximumdischargecurrent,theorder shall be given to connect the back-up generator.

Parameter 419: Power supplied by the back-up generator and which permits the generator disconnection. This parameter is given as a percentage and is applied to the back-up generator rated power. To disconnect the generator, the power consumed by the loads



must be less than this % of the generator rated power.

Note: These parameters are not applicable if the INGETEAM ENERGY S.A. wattmeter has not been installed.

Battery equalisation

(Parameter 415)

Optionally, it is possible to force the back-up generator to start-up in order to perform a battery equalisation charge.

The equalization charge can be required manually or after a certain number of charge cycles (parameter 009). In both cases the back-up generator can be programmed to remain connected until the equalization has been completed, ensuring that this charge is performed correctly.

If this option is not enabled, then the equalisation process will depend on the availability of the renewable energies.

Disconnection criteria

The back-up generator will disconnect once the cause of the connection order has disappeared and if there are no other criteria which require it to remain on.

Manual start-up

If the generator has been started-up manually, then it must be disconnected in the same way. The Ingecon® Hybrid MS will check the other criteria.

– Operation with a number of back-up generatorsSome installations require the use of a number of back-up generators in parallel. The Ingecon® Hybrid MS can read the connection of up to four generators.

Observations:

- The Ingecon® Hybrid MS will give a single order to start-up the back-up generator. The selection of the generator to be started-up is a task that is external to the Ingecon.

- The Ingecon® Hybrid MS will give a single order to close the power contactor. The selection of the contactor to be closed is a function that is external to the Ingecon.

- The start-up, synchronisation and parallel connection of the other generators shall be performed with a control device which is external to INGETEAM ENERGY S.A. Thisdevicemustrecordtheoperatingpointofeachgenerator,forefficientoperation.

- At the time when the generator is disconnected, the Ingecon® Hybrid MS will send a single signal to the open the power contactor.

- At the time when the generator is shut-down, the Ingecon® Hybrid MS will send a single signal to shut-down the generator.

AC Loads



14.4 VOLTAGE GENERATION. LOAD CONNECTIONThere are a great variety of inverters used for off-grid installations, producing wave forms with different characteristics. Normally a distinction is made between inverters producing asquarewave,modifiedsinewaveorpuresinewave.Thelatteristhewavewhichmostresembles the AC voltage of the conventional electricity grid.

Square wave

Modified sine wave

Pure sine wave

V

The Ingecon® Hybrid MS units provide a pure sine wave voltage, thereby achieving the correct operation for the majority of the loads currently on the market.

In any case, it should not be forgotten that this is not a conventional electrical system in which the consumption of the installation is negligible compared to the grid capacity. We are dealing with an off-grid system, whose stability is compromised by the relationship between the power being consumed at any given time and the total power for which the system has been dimensioned. This should be taken into account when distributing loads, in order to try and avoid load interaction as much as possible.

It is also advisable to balance consumption in the three phases.

In some cases, it may be necessary to install starters or speed controllers to limit the start-up peak of motors, pumps, etc.
