Note!
Growatt has two different wiring systems in their program. The differences are in the pin wiring. The
old inverters have a round plug and 2-pin wiring, and new inverters have 3-pin wiring and a terminal
block connector in the inverter.
3-pin wiring
Overview
•
Integrated interface.
•
Where to connect: inside the inverter.
•
3-pin wiring.
•
The communication address has to be assigned.
•
Installation steps:
•
Switch off the inverters and the Solar-Log™.
•
Connect the inverters to the Solar-Log™.
•
Connect the inverters to each other.
•
Assign the communication address.
Connect the inverters to the Solar-Log™
The wiring is done
•
using a self-made shielded 3-wire data cable with a terminal block connector.
Procedure
1. If you are making the cable yourself, connect the wires as shown in the following diagram:
