The Powador xi-series.The next generation of solar inverters

We integrated new features – and enhanced existing onestransformerless .

.

With its xi series, KACO has set another milestone in the development of its proven and rugged Powador

solar inverters. The, completely transformerless technology has become the hallmark of KACO and

characterizes its highly efficient and exceptionally reliable inverters. The xi-series combines all the

features of a state-of-the-art energy converter: user convenience, innovative technology, maximum

degrees of efficiency and ruggedness.

Taking a pioneer role in the field of transformerless technology, KACO has focused primarily on maximum

efficiency, a fact already proven very impressively by the predecessor of today’s xi-series. The new xi-

series has been designed to follow-up this tradition – exhibiting degrees of efficiency that can only be

achieved by genuine transformerless inverter technology. In addition, KACO continues to count on its

unique MPP technology – ensuring that you will remain a step ahead as far as the total yield of your

installation is concerned.

The user convenience of KACO devices leaves nothing to be desired. All the important information can be

read off an illuminated display. Grid-side connection is via sturdy terminal screws, whereas on the DC

voltage end you may choose between terminal screws or plug-type connectors (Tyco or MC-type).

Installation is facilitated by means of a mounting plate, which is simply attached to the wall for suspension

of the inverter - wherever you wish to use the device. Protection class IP54 makes the inverter well-

equipped for any type of operating environment.And of course, it comes with a host of accessories.

Longevity and reliability have been the outstanding characteristics and key objectives of all KACO

developments. Mid of the last century, KACO created the basis for reliable inverters with its chopper units.

As reliability has remained a key characteristic of all KACO inverters the focus continues to be on the use

of convection cooling for KACO inverters.

In addition, KACO still relies on its proven 3-phase monitoring, which forms the basis of your interface

between the energy provider and PV installation. This completely passive technology enables parallel

operation of several inverters just as well as operation under difficult grid conditions. High reliability and the

absence of shutdowns due to system faults are the results.

The xi-series – KACO’s next logical step in the further development of our outstanding Powador solar

inverters.

The xi-series:

The next logical step in the further development

of our proven Powador solar inverters.

The generation of transformerless solar inverters.

“We want all wishes to come true!” - With this objective in mind, R&D engineers at KACO have pursued ideas and

possible enhancements of our well-proven transformerless inverter series, Powador. This series includes redundant

3-phase monitoring and AC/DC-universal fault-current protection. The fact that 3-phase monitoring has been adopted

in the VDE standard 0126-1 clearly confirms our philosophy at KACO: “Maximum reliability and functionality to our

customers’ benefit.” The grid monitoring feature is adapted to the requirements of the standard, now making it possible

to use KACO inverters for multi-inverter installations without requiring any additional effort. Discussions with your

Electric Board are now a thing of the past. The adjustable interface mode will make you even more flexible when

selecting your accessories or data recording and evaluation. This feature allows on-site selection of the desired

interface protocol (RS232 or RS485). In addition, a potential-free fault-message relay is integrated. The enclosure

design underlines all these product features, while maintaining the proven reliability and functionality of these devices.

Protection class IP 54 makes our inverters suitable for harsh operating conditions, and there are absolutely no

compromises as far as our guarantee and services are concerned. Our seven-year guarantee (with an option to be

extended to 11 years) is aimed at setting new standard.

efficiency.

Highest degrees of efficiency can be translated into added value. If you compare our values to those of other

manufacturers, you will discover that the efficiency yielded by a single solar inverter made by KACO will be higher than

that of other parallel circuit designs, even when used under partial-load conditions.

convection cooling.

The sun won’t send us an electricity bill. It provides us with free energy, which in contrast to fossil fuels, will remain

available for many decades. It is our commitment to design devices and systems that yield maximum outputs from solar

energy, so as to preserve our planet as a natural environment for the generations to come.

The max. solar generator power is a safe recommended

value. Other ratings may be recommended by your

authorized dealers or installation experts based on their

own experience.

Please note the following dimensioning rules:

No-load voltage should not exceed 800VDC at a

module temperature of -10°C.

The MPP operating voltage should not fall below

350VDC at +60 or, respectively, +70°C.
