Power Connection

Load

Communication Connection

WARNING:

Do not connect the current sharing cable between the inverters which are in different phases.

Otherwise, it may damage the inverters.

6. PV Connection

Please refer to user manual of single unit for PV Connection.

CAUTION:

Each inverter should connect to PV modules separately.
