Product Details

Work Diagrams of solar energy system

(1) PV Solar Priority Mode

The power supply to the load is fed by the solar panel input. The amount of electricity generated by the solar cell is stored in the powerwall in addition to the user load. When the amount of electricity generated by solar does not meet the user load, the amount of electricity stored in the battery bank is replenished to the load.

(2) AC Priority Mode

The power supply of the load is provided by the mains input. Solar power only charges the house battery; When the battery power is seriously insufficient, the AC mains will start to charge the battery.When the AC mains is powered off or abnormal, the system will switch to the battery to supply power to the load.
