Off-Grid (II)
PV energy supply priority setting:
PV power will charge battery first. After battery is fully charged, if there is remaining
PV power left, it will provide power to the load. 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 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.
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.
NOTE: It’s allowed to set up AC charging duration.
Load supply source:
When PV power is available: 1st PV, 2nd Grid, 3rd 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.
1st Battery, 2nd Load
When PV power is not available:
1.
1st Grid, 2nd Battery: Grid will provide power to the load at first. If grid is not
available, battery power will provide power backup.
2.
1st Battery, 2nd Grid: Battery power will provide power to the load at 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 1st Grid and 2nd Battery order. Otherwise, it will cause
battery damage.

Off-Grid (III)
PV energy supply priority setting:
PV power will provide power to load first and then charge battery. Feed-in to the grid
is not allowed under this mode. The grid relay is NOT connected in Inverter mode.
That means the transfer time from inverter mode to battery mode will be about
15ms. If connected load is over 5KW and grid is available, this inverter will allow grid
to provide power to the loads and PV power to charge battery. Otherwise, this
inverter will activate fault protection.
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.
2.
PV only: It is only allow PV power to charge battery.
