Four Ways to Charge Inverter Batteries

The inverter has four ways to charge the battery. If you choose the mains to charge the battery, pay attention to the efficiency will be reduced. Because the commercial power first charges the battery and then discharges it, there will be a certain amount of power loss. Generally, the charging and discharging efficiency of off-grid inverters are about 90%.

The four charging methods of the inverter are as follows:

1. Photovoltaic (PV) priority: Photovoltaic (PV) gives priority to charging the battery. Only when there is no photovoltaic (PV) energy, the mains will charge the battery. This mode is suitable for users with relatively expensive electricity prices and low power supply requirements.

2. Mains priority: The mains will give priority to charging the battery, and the photovoltaic will charge the battery only when there are no mains. This model is suitable for places where electricity is cheap but power outages are frequent.

3. The inverter charges the battery from the mains and photovoltaics at the same time. This mode is suitable for areas with low electricity prices and large demand for power supply.

4. Separate photovoltaic charging: no matter whether there is mains power, only photovoltaic charging is used. This mode is suitable for users with high electricity prices and low electricity demand.

The above four inverter operating modes can be selected when both photovoltaic and commercial power is available. If there is no complementary power source, the inverter will be in operating mode, i.e. the photovoltaics are charged separately.
