The power generated from PV will be used to supply the local loads firstly, then to charge
the battery , the redundant power will export to the public grid.
4.1.2 Self-use with generator
① when the SOC of battery is normal , Battery and PV supply the load together, the
generator is off
PV power
＞
load PV power
＜
load
② when SOC of battery is low
，
BD 30-150kW-P turn on the generator using dry contactor
Automatically. The generator supply the loads.
③ when the PV has energy will charge the battery, generator supply the load.
