Operating of the Inverter
●
Peak time discharge
Peak time discharge mode
Automatic power regulation
*Peak time discharge power(500-10000W)
３０００
The peak time discharge setting is only effective when the user selects the peak shaving
and valley filling mode. During the peak time, the default setting is that the system automat-
ically adjusts the discharge power according to the household power detected by the smart
meter; If the smart meter is not installed, the user can select a fixed discharge power
according to the approximate power consumption.
●
Battery backup mode charging setting
Charging with grid in storage mode
*Storage mode charge SOC(20-100%)
４０
*Storage mode charge power(500-10000W)
４０００
The battery backup mode charging setting is only effective when the user selects the
battery backup working mode. You can set whether to turn on the mains power to charge
the battery, and the charging power and battery charging cut-off SOC.
