PV energy supply priority setting:
1 Load, 2 Battery and 3 Grid.
PV power will provide power to the load first. Then, it will
charge battery. If there is any remaining 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.
