Matters Needing Attention In Three-phase Parallel Operation
1. Parallel operation in Three phase with up to 6 units.
2.
WARNING:
It’s required to connect battery for parallel operation, it is forbidden to use parallel without batteries
3.
WARNING:
It is forbidden for inverter to share the same solar panel group.
4.
WARNING:
Make sure all cables are of the same length, Otherwise, there will be voltage difference
between inverter and battery to cause parallel inverters not working.
5. Set the parameters of each inverter independently (working mode, three- phase parallel function and set
A/B/C phase sequence).
WARNING:
When working in parallel, the working mode of each inverter must be the same working mode,
output frequency.
6. After setting the parameters, turn on each inverter in turn.
7.
WARNING:
When running in parallel, all inverters must share the battery pack.
8. WARNING:
Do not connect the current sharing cable between the inverters which are in different phase.
Otherwise ,it may damage inverters .
