PV energy supply priority setting: 1
st
Load, 2
nd
Battery and 3
rd
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

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.

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
st
Grid, 2

Battery: Grid will provide power to the load at first. If grid is not
available, battery power will provide power backup.
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
st
Grid and 2
nd
Battery order. Otherwise, it will cause
battery damage.
