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: 1st PV, 2nd Battery, 3rd 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, Grid will back up the load.
When PV power is not available:
1. 1st Grid, 2nd Battery: Grid will provide power to the load at first. If grid is not
available, battery power will provide power backup.
2. 1st Battery, 2nd 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 1st Grid and 2nd Battery order. Otherwise, it will cause
battery damage.
