Working logic under peak time:
PV energy supply priority:
1 Load, 2 Battery and 3 Grid
PV power will provide power to the load first. If PV power is
sufficient, it will charge battery next. If there is remaining PV
power left, it will feed-in to the grid. Feed-in to the grid is
default disabled.
Battery charging source:
PV only
Only after PV power fully supports the load, the remaining PV
power is allowed to charge battery during peak time.
Load supply source:
1 PV, 2 Battery, 3 Grid
PV power will provide power to the load first. If PV power is not
sufficient, battery power will back up the load. If battery power
is not available, grid will provide the load. When PV power is not
available, battery power will supply the load first. If battery
power is running out, grid will back up the load.
Working logic under off-peak time:
PV energy supply priority:
1 Battery, 2 Load and 3 Grid
PV power will charge battery first. If PV power is sufficient, it will
provide power to the loads. The remaining PV power will feed to
the grid.
NOTE: The max. feed-in grid power setting is available in
parameter setting. Please refer to software manual.
Battery charging source:
PV and grid charge battery
PV power will charge battery first during off-peak time. If it’s not
sufficient, grid will charge battery.
Load supply source:
1 PV, 2 Grid, 3 Battery
When battery is fully charged, remaining PV power will provide
power to the load first. If PV power is not sufficient, grid will
back up the load. If grid power is not available, battery power
will provide power to the load.
Grid-tie with backup (IV):
Users are only allowed to set up peak time and off-peak
electricity demand.

PV energy supply priority setting:
1 Load, 2 Battery and 3 Grid
PV power will provide power to the load first. If PV power is
sufficient, it will charge battery next. If there is remaining PV
power left, it will feed-in to the grid.
Battery charging source:
1. PV and Grid: It’s allowed to charge battery from PV power
first. If it’s not sufficient, 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.
Load supply source:
When PV power is available:
1. 1 PV, 2 Battery, 3 Grid
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: 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 with backup (V):
Under this mode, inverter will
automatically disconnect from grid to allow battery to support
loads when battery can not discharge due to high grid voltage.
