5.16. Advanced Settings for Paralleling Inverters
To configure multi-inverter settings, click on the ADVANCE icon.
The Sunsynk parity inverter can be wired standalone or where more power is required it can be
connected in parallel either single or 3 phase configuration. The maximum number of inverters
that can be paralleled in a single phase utility grid is three (18kW and 22.8kW for the 6kW and 7.6
kW model, respectively) and the maximum number that can be paralleled in a three-phase utility
grid is nine (54kW and 68.4kW for the 6kW and 7.6 kW model, respectively).
To parallel six inverters in a three-phase utility grid is necessary to set three inverters as master
and three as slaves:
Phase A: Master A and Slave A
Phase B: Master B and Slave B
Phase C: Master C and Slave C
For stability, all the batteries need to be connected in parallel. It is recommended a
minimum cable size of 50mm diameter with fuse isolators to each inverter.
What this page displays:
If the inverter operates as a master or a
slave.
Modbus Device ID – ‘Modbus SN’ that
must be unique for each inverter
connected to the bus/wire.
What you can do from this page:
Set the inverter as a master or slave per
bus/wire.
Set the phase in which the inverter will be
paralleled.
Set the Modbus SN for paralleling.
