Option
3: Grid-Tie with Backup (III)
PV Energy Supply Priority Setting: PV will supply energy in the following order:
1. Loads
2. Grid
3. Battery
PV will provide power to the loads first, if there is excess PV generation, it will feed-in to the grid.
If feed-in power reaches max feed-in power setting, the remaining generation will charge the
battery.
NOTE: The Max Feed-In Grid Power Setting is available in parameter settings within the
software and should be set based on your utility interconnection agreement.
Charging Source:
1. PV and Grid (Default): Allows charging of battery from PV first. If PV source is not sufficient to charge
the battery, the grid will charge the battery also.
2. PV Only: Only allows charging of battery from PV array. Grid will not be used to charge the battery.
3. None: No battery charging will be provided from PV or Grid.
Load Supply Source (PV is Available): Loads will be supplied in one of the following options:
Option 1:
1. PV
2. Battery
3. Grid
PV will provide power to the loads first. If PV is not sufficient to support the loads, battery
will provide additional power to the loads. When battery reached LBCO or is not available,
grid will power the loads.
Option 2:
1. PV
2. Grid
3. Battery
PV will provide power to the loads first. If PV is not sufficient to support the loads, grid will
provide additional power to the loads. If the grid is not available, battery will provide backup
power to the loads.
Load Supply Source (PV is unavailable): Loads will be supplied in one of the following options:
1. 1

Battery (Default): Grid will provide power to the loads first, if grid is not available
battery will supply power to loads as back-up.
