Option 4: Grid-Tie with Backup (IV): Time of Use
Users are only allowed to set up the peak time and off-peak times for electricity demand, time-of-use (TOU)
settings.
Working Logic Under Peak Time
PV Energy Supply Priority Setting: PV will supply energy in the following order:
1. Battery
2. Loads
3. Grid
PV will charge the battery first, if there is excess PV it will provide power to the loads. If there is
remaining PV generation, it will feed-in to the grid.
Charging Source: PV Only
Only after PV power fully supports the loads is remaining PV power allowed to charge the
battery during peak times.
Load Supply Source: Loads will be supported in the following order:
1. PV
2. Battery
3. Grid
PV will provide power to the loads first. If PV is not sufficient to support the loads the
batteries will support the loads. If the battery reaches LBCO or cannot support the loads, the
grid will provide power to the loads. When PV power is unavailable (nighttime), battery will
supply the loads first. If the battery reached LBCO, the grid will back-up the loads.
Working Logic Under Off-Peak Time:
PV Energy Supply Priority Setting: PV will supply energy in the following order:
1. Battery
2. Load
3. Grid
PV will charge the battery first, if there is excess PV generation, it will provide power to
the loads. If there is remaining PV generation, it will feed-in to the grid.
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: PV and Grid Charge Battery
PV generation will charge the battery first during off-peak times. If it is not sufficient, the
grid will also charge the battery.
Load Supply Source: Loads will be supported in the following order:
1. PV
2. Battery
3. Grid
PV will provide power to the loads first. If PV is not sufficient to support the loads the
batteries will support the loads. If PV power is not sufficient, the grid will provide power
to the loads. If grid power is not available, battery power will provide power to the loads.

Feed-in to the grid is disabled by default.
