7.7 PARALLEL SYSTEM CONNECTION
Connections for Parallel System
The hybrid inverter supports parallel connection to expand power and energy capacity to suit
different usage scenarios. Up to 16 units can be paralleled to reach a capacity of 256kW. The
inverters can be used in single phase, or in a three phase system (for three or more inverters).
The parallel wiring diagrams are as follows. If the inverters fail, users can switch loads to the grid.
Contact the inverter supplier for more detailed guidance on paralleling the system.
REMINDER:
• All setting changes for parallel inverters must be done while in Standby Mode.
• If the system is connected to a lithium battery, the host battery must
communicate with the inverter that is set as master in the parallel system.
• Keep all settings the same for each inverter in the parallel system on the
remote monitor!!
• If the number of PV panels connected to each inverter cannot be evenly
divided, it is recommended to have more PV panels on the master inverter.
REMINDER:
Put the CAN communication pin to ON status for the first and the last inverter and
OFF for inverters in between.
Both switches in the “ON” position translate to address 1. Both switches in the “OFF”
position translates to address 0.
