to the value of End-of-Discharge SOC for Lithium Batteries(%), the loads

3. After the ESS discharge ends, the PV system charges the ESSs. When the value
of Available SOC for Lithium Batteries(%) is reached, the ESSs resume
power supply to loads.

● 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.
● 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.
