LCD setting For Lithium Batteries
To make the inverter communicate with the battery BMS, the battery type should be set to “LI” in Program
05.
Please refer to “05: LI” for details.
Note:
When multiple inverters are paralleled with multiple lithium batteries, please follow the below setup.
1 Out of the lithium batteries, set one unit as the master and the rest as slave as per the lithium DIP/ADS
switches.
2 Connect the master battery to the inverter which shows “Host”.
If the user connects the master battery to one of the rest the slave inverters in the group, the inverter can
automatically work as the master unit, but the communication will be slower.
3.7 Inverter Parallel Operation
The M5000H-48BP inverters can be stacked up to 6 pcs to expand output power in 230Vac or create
230/400Vac three phase.
The M3048BP can be stacked up to 6 pcs to expand output power in 120Vac or create 120/208Vac three
phase.
When they are stacked, all the inverters will share the loads evenly. Each will be ready output full power
even the load is under nominal power, none of them will go into power saver mode.
This is designed to handle sudden loads fluctuations.
Note:
When there is more than one inverter paralleled in one phase, if the slave unit shut off, the rest inverters in
the system will continue operate.
If the master unit shuts off, all the rest inverters will shut off.
WARNING:
For parallel operation, each inverter should connect to separate PV arrays for optimal performance. They
should never be connected to the same solar array, or damage will occur.
