Off-Grid
Off-Grid (I): Default setting for off-grid mode.
PV energy supply priority setting: 1
st
Load, 2
nd
Battery
PV power will provide power to the load first and then charge battery. Feed-in
to the grid is not allowed under this mode. At the same time, the grid relay is
connected in Inverter mode. That means the transfer time from inverter mode
to battery mode will be less than 15ms. Besides, it will avoid overload fault
because grid can supply load when connected load is over 4KW.
Battery charging source:
1. PV or Grid: If there is remaining PV power after supporting the loads, it will
charge battery first. Only until PV power is not available, grid will charge
battery. (Default)
2. PV only: It is only allow PV power to charge battery.
3. None: It is not allowed to charge battery no matter it’s from PV power or grid.
