PV energy supply priority setting:
1 Load, 2 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 3KW.
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 PV, 2 Battery, 3 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 power is running out or not available, grid will back up
the load.
2. 1 PV, 2 Grid, 3 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 Grid, 2 Battery
Grid will provide power to the load at first. If grid is not
available, battery power will provide power backup.
2. 1 Battery, 2 Grid (Default)
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 1 Grid and 2
Battery order. Otherwise, it will cause battery damage.

Grid-Tie
Under this operation mode, PV power only feeds-in to the
grid. No priority setting is available.
Off-Grid
Off-Grid (I): Default setting for off-grid mode.
PV energy supply priority setting:
1 Battery, 2 Load
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 3KW.
