is sufficient, the utility stops charging.
Note: The PV and mains can only be charged at the
same time when the mains bypass output is loaded.
When the inverter is operating, only PV charging can
be initiated, not utility charging.
CUB
Utility is the first priority in charging, PV charging the
battery only when utility is not available.
CSO
PV is the first priority in charging, utility charging the
battery only when solar power is not sufficient.
OSO
PV charging only, no utility charging.

not be set after the BMS communication is successful.
12
Battery over- discharge
voltage (delay off)
42 default
When the battery voltage is lower than the judgement
point, and triggers the parameter [13], the inverter
output is switched off, the setting range is 40V~48V,
the step is 0.4V, valid when battery type is custom and
lithium battery.
13
Battery over- discharge
voltage delay time
