Parallel Function
1. Introduction
This inverter can be used in parallel in only split phase systems. A maximum of nine units can parallel together.
The supported maximum output power is 54kW/54KVA.
*If you want to use only one breaker at the battery side for the whole system, the rating of the breaker should be
X times current of 1 unit. “X” indicates the number of inverters connected in parallel.
Note: Use a 40A 2 Pole AC breaker for only 1 unit and install one breaker for the AC input in each inverter.
