When the mains is available, the genset shuts down. The mains supplies
power to loads and charges the ESSs.
When the mains is unavailable:
a. The 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 b. If the genset fails to start, the ESSs discharge
to the value of End-of-Discharge SOC for Lithium Batteries(%), and
the loads power off.
b. The genset supplies power to loads and charges the ESSs until the value
of Genset Shutdown SOC(%) is reached. The mode switches to a.

● Lithium battery SOC: lithium battery real-time capacity percentage.
● End-of-Discharge SOC for Lithium Batteries(%): In any mode, the ESSs discharge to
the value of End-of-Discharge SOC for Lithium Batteries(%), protecting the batteries.
● Genset Startup SOC(%): The ESSs discharge until the lithium battery SOC is less than
or equal to the value of Genset Startup SOC(%). Then the genset is started to prevent
load power-off.
● Genset Shutdown SOC(%): The ESSs are charged until the value of Available SOC for
Lithium Batteries(%) is reached. Then the genset is shut down. This reduces the genset
runtime.
