SINGLE PHASE HI 10/12kW | User Manual58
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.
Ex_Meter For CT: When in a Three-phase system with a CHNT Three-phase energy meter (DTSU666),
click the corresponding phase where the hybrid inverter is connected. E.g. when the hybrid inverter out-
put connects to A phase, please click A Phase.
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.
Select the corresponding meter type according to the meter installed in the system.
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 conguration. The maximum number of inverters that can be paral-
leled in a single phase utility grid is 16 and the maximum number that can be paralleled in a three
phase utility grid is 15A.
A master single phase inverter is capable to operate with other 15 slaves inverters. Thus, to parallel 16 in-
verters in a single phase utility, one will operate as the master, and the other 15 will operate as slaves.
To parallel 15 inverters in a three phase utility grid is necessary to set three inverters as master and the
others as slaves:
Phase A: Master A and 4 Slaves A
Phase B: Master B and 4 Slaves B
Phase C: Master C and 4 Slaves C
In a three phase utility grid, the paralleled inverters will operate as a normal three-phase supply with perfect
phase rotation, capable of power single phase (220 V
LN
) and three phase (380 V
LL
) loads.
For stability, all the batteries need to be connected in parallel. It is recommended a minimum cable size of
50mm2 diameter with fuse isolators to each inverter.
