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 Communivations Wiring 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 –15TL3
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.

5.2 BLUEPLANET 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. Install the ABS insulation plate. NB: This insulation
plate must be fitted. 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.

5.3 BLUEPLANET 50
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.
The Kaco Interface card is located on the inside of the door panel.
Blueplanet 50 Interface Card
Position the Microcare interface card at a slight angle and seat the USB connection first, then push
the Microcare interface card downwards and seat the 2 pin and 6 pin sockets towards the mating
connectors till fully seated.

6. TESTING THE INSTALLED LIMITER AND ENERGY METER
Ensure that all the AC load circuit breakers are switched off.
DC diconnect switch in the OFF position.
Connect the grid supply to the inverter using the external AC circuit breaker/s.
Wait until the inverter starts-up and the start-up screen appears.
6.1 3 Ph Energy Meter
If the telephone Icon appears on the first line of the Energy Meter display,
it confirms that the Energy Meter is communicating with the inverter.
Press to Access the Energy Meter Power Menu screen. 0kW should display.
6.2 Single Phase Energy Meter
If the telephone Icon appears on the last line of the Energy Meter display,
it confirms that the Energy Meter is communicating with the inverter.
Press to Access the Energy Meter Active Power Menu screen. 0kW should display.
Please Note:
If the energy meter indicates a “-“ negative KW
reading, the CTS are connected the wrong way
round.
