Type 3: Four inverters in one phase and one inverter for the other two phases:
Power Connection
Communication Connection

Support three-phase equipment
Step 1: Check the following requirements before commissioning:
Correct wire connection
Ensure all breakers in Line wires of load side are open and each Neutral wires of each unit are connected together.
Step 2: Turn on all units and configure LCD program 23 as P1, P2 and P3 sequentially. Then shut down all units.
NOET:
It’s necessary to turn off switch when setting LCD program. Otherwise, the setting cannot be programmed.
Step 3: Turn on all units sequentially.
LCD display in L1-phase unit
LCD display in L2-phase unit
LCD display in L3-phase unit
Step 4: Switch on all AC breakers of Line wires in AC input. If AC connection is detected and three phases are matched with unit
setting, they will work normally. Otherwise, if will display warning 15/16 and they will not work in the line mode.
LCD display in L1-phase unit
LCD display in L2-phase unit
LCD display in L3-phase unit
Step 5: If there is no more fault alarm, the system to support 3-phase equipment is completely installed. Step 6: Please
switch on all breakers of Line wires in load side. This system will start to provide power to the load.
Note 1: To avoid overload occurring, before turning on breakers in load side, it’s better to have whole system in operation
first.
Note 2: Transfer time for this operation exists. Power interruption may happen to critical devices, which cannot bear transfer time.
