Remarks
This parameter is set according to the actual
requirements.
Default: -20°C.
This parameter is set according to the actual
requirements. The temperature compensation
coefficient refers to the variable of the float
charging voltage of the battery set when the
temperature of the battery set changes by every 1°
C.
Default: 80 mV.
This parameter is set according to the actual
requirements.
Default: forbid.
This parameter is set according to the actual
requirements.
Default: permit.
This parameter is set according to the actual
requirements.
Default: 44 V.
This parameter is set according to the actual
requirements.
Default: 43 V.
This parameter is set according to the actual
requirements. When the AC voltage exceeds the
preset overvoltage alarm threshold, the system
reports an AC overvoltage alarm. In this case, the
rectifier unit powers off automatically to protect
the system.
Default: 280 V.
This parameter is set according to the actual
requirements. When the AC voltage falls below
the preset undervoltage alarm threshold, the
system reports an AC undervoltage alarm. In this
case, the rectifier unit powers off automatically to
protect the system.
Default: 180 V.
