7.2. THREE-PHASE CONFIGURATION
The Sunsynk Hybrid Inverter can also be paralleled in a three-phase system with perfect phase rotation.
In this case, you need to have three masters, and all the others are slaves. DO NOT forget that each inverter
still needs its own unique MODBUS communication number.
Phase A: Master A and Slave A
Phase B: Master B and Slave B
Phase C: Master C and Slave C
1)
Check if all inverters have the same operating system and the latest software version and are the same
model.
2)
On the multi inverter page, select 'parallel' and choose the master, which is normally the central inverter.
3)
Ensure that you have good quality communication cable between the inverters.
4)
Set all the other inverters to be slaves
5)
Each inverter needs its own unique MODBUS number.
6)
Each inverter needs its own data logger.
7)
You only need one CT coil, which is connected to the master.
8)
All batteries are wired in parallel.
9)
The master is the only one that communicates with the battery BMS.
