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. The
grid relay is NOT connected in Inverter mode. That means the
transfer time from inverter mode to battery mode will be less
than 15ms.

Off-Grid (III)
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: 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: 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.

Load supply source:
When PV power is available: 1 PV, 2 Battery, 3 Grid
PV power will provide power to the load first. If it’s not
sufficient, battery power will back up the load. Only after battery
power is running out and stop providing the load, Grid will back
up the load. At this time, battery power is in low level and PV
power only can charge battery when “Allow to charge battery” is
enabled. Only when battery voltage is back to re-discharging
point, PV power will provide power to the load again.
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: 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.
