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 in 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 5KW.
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 PV power or grid.
Load supply source:
When PV power is available:
1.
1
st
PV, 2
nd
Battery, 3
rd
Grid (Default)
PV power will provide power to the load first. If it’s not sufficient, battery power will provide
power to the load. When battery is running out or not available, grid will back up the load.
2.
1
st
PV, 2
nd
Grid, 3
rd
Battery
PV power will provide power to the load first. If it’s not sufficient, grid will provide power to the
load. If grid is not available at the same time, battery power will back up.
When PV power is not available:
1.
1
st
Grid, 2
nd
Battery
Grid will provide power to the load first. If grid is not available, battery power will provide power
backup.
2.
1
st
Battery, 2
nd
Grid (Default)
Battery power will provide power to the load first. If battery power is running out, grid will back
up the load.
NOTE: This option will become ineffective during AC charging time and the priority will
automatically become 1
st
Grid and 2
nd
Battery order. Otherwise, it will cause battery damage.
