4-3. Support 3-phase equipment

 

One inverter in each phase: 

Power Connection 

 

Communication Connection 

 

 

WARNING: 

Do NOT connect the current sharing cables between the inverters in different phases. Otherwise, 

it may damage the inverters. 

NOTE:

 

For parallel model operation, please refer to LCD program 28 

 

5. PV Connection   

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

CAUTION:

 Each inverter should connect to PV modules separately.
