Self-consumption mode
Self-consumption mode is standard hybrid inverter mode.
In this mode, PV power is supplied in following priority :
1. Supply for home load.
2. Charge the battery until it is full.
3. Feed-in the remaining power to grid.
When there is no PV power, battery starts to discharge and supply home load until it’s empty.
If you had set the time settings, the behavior of hybrid inverter will change.
We will explain it in Page 80.
