The PV system and ESSs supply power to loads. When the lithium battery SOC
is less than or equal to the value of Genset Startup SOC(%), the genset
starts and the mode switches to 2. If the genset fails to start, after the ESSs
discharge to the value of End-of-Discharge SOC for Lithium Batteries(%),
the loads power off and the mode switches to 3.
The genset supplies power to loads. At the same time, the genset and PV
system charge the ESSs until the value of Genset Shutdown SOC(%) is
reached. The mode switches to 1.
The PV system charges the ESSs until the value of Available SOC for Lithium
Batteries(%) is reached, and the mode switches to 1.
