When PV power is not available:
1.
1
st
Grid, 2

Battery: Grid will feed load first. If grid is not available, battery will
provide backup.
2.
1

Battery, 2
nd
Grid: Battery will feed the load first. If battery is running low, 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.
Grid-tie with backup (IV):
Users can only set up peak time and off-peak
electricity demand.
Working logic under peak time:
PV energy supply priority:
1

Load, 2

Battery and 3

Grid
PV power will feed the load first. If PV power is sufficient, it will charge battery
next. Any excess PV power will be fed into the grid. Grid feeding is disabled by
default.
Battery charging source:
PV only
Only if PV power can support the load, is the remaining PV power allowed to
charge battery during peak time.
Load supply source:

Grid
PV power will feed the load first. If PV power is insufficient, battery power will back
up the load. If battery power is not available, grid will support the load. When PV
power is not available, battery power will supply the load first. If battery power is
running low, grid will back up the load.
