Most hybrid inverters can be set to the following four modes:

Grid-connected mode: It functions just like a normal solar inverter without batteries.

Hybrid mode: Excess solar energy is stored during the day and used at night to improve self-sufficiency.

Backup mode: When the grid has power, it functions like an ordinary solar inverter, but it can automatically switch to backup power mode when the grid is cut off.

Off-grid mode: The working principle of this mode is very similar to that of an off-grid inverter, which will use excess solar energy to charge the battery and power the appliances in the home without an external grid connection.
