● Lithium battery SOC: lithium battery real-time capacity percentage.
● Backup Power SOC(%): In Maximize PV Consumption mode, when the mains is
normal, the lithium battery SOC is greater than the value of Backup Power SOC(%) to
provide backup power.
● 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.
● Available SOC for Lithium Batteries(%): When the ESSs have only PV input (no AC
input), the ESSs discharge to the value of End-of-Discharge SOC for Lithium
Batteries(%). The PV system charges the ESSs until the value of Available SOC for
Lithium Batteries(%) is reached. Then the ESSs supply power to loads. This prevents
unstable power supply when the irradiance is low.
● 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.
