INTRODUCTION

1. INTRODUCTION The KACO inverter if purchased with Interface card, Limiter module and WIFI module will be installed

and configured by MICROCARE. The Energy Meter parameters are also configured by Microcare.

The Microcare “KACO ” Grid Tied Limiter (GTL) is ONLY COMPATIBLE WITH THE KACO Grid Tied Inverters. The limiter is used where feeding back into the grid is not allowed or not profitable to the user. The Grid Tied Limiter will insure that the Grid Tied Inverter only produces as much power as the load is using at any given time.

The GTL prevents the Grid Tied Inverter from exporting power back into the Grid. The GTL measures

the power required by the load and notifies the grid tied inverter to limit the power generated to equal

that of the AC Load. Because no extra power is generated no power can be exported.

The Limiter module can be purchased with or without the WIFI module. The limiter module is

programmed via the Wi-Fi module.

The electrical diagrams and block diagrams are intended for illustrative purposes only and are not

intended to provide an electrical design. The installation information in this manual is for information

purposes only.

1.2 Basic Multiple Inverter Block Diagram

Each inverter is fitted with a Microcare interface card.

A Limiter module is only fitted to one Inverter.

The Limiter is programmed for the total installed Inverter Power.

The energy meter reads the load power and sets the limit for each inverter via the Limiter module.

Communication between the inverters is established via the Microcare Interface Card MC Comms Port.

Wi-Fi modules are required for logging purposes.

5. INTERFACE CARD INSTALLATION 5.1 BLUEPLANET 3TL1 – 20TL3 Shut down the Kaco Grid Tied Inverter as per the Kaco manual before installing the Microcare interface card or making any cable connections between devices. Familiarise yourself with the layout of the Microcare Interface card, Limiter Card and the WIFI module. Remove the bottom lid of the inverter. Locate the Kaco Interface card and slot the Microcare interface card into the Kaco interface card. Ensure that the USB, 6 Pin and the 2 Pin connector seat firmly into the mating sockets.

The start-up screen should display 0kW

Push - The main Menu Screen appears,

Push - The Measurement /Generator screen appears.

Push - The Measurements/Grid Menu appears,.

Push - The Power Control Menu Appears.

Start-up Screen Main Menu/Measurements Menu

Measuremenst/Generator Menu Measurements/Grid Menu

Note that the Power Control % should now read “ 0%”.

12

Turn on the load circuit breakers and turn on a constant load.

For explanation purposes, if the installed inverter is a 5kW inverter an the load is 2kW.

2kw/5kw x 100 = 40%,

The inverter Power Control Menu should change from 0% to 40%.

The Energy Meter should display 2kW

Switch the inverter DC connect switch to the on position.

Wait until the Dc start up procedure is complete

The Inverter should display the following information.
