● 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.

Description
Output Voltage Set the output voltage and output frequency based on the
local power grid standards.
Output Frequency
Bypass Input
Overvoltage Limit
Set the bypass input overvoltage and undervoltage
protection thresholds. When the bypass input voltage
reaches the preset value, the system stops output
immediately and reports a bypass module protection
alarm.
