During the day, the solar panel generates power during sunlight condition, the solar array voltage should meet the requirements of the Solar system input voltage through the series and parallel connection.Then the battery is charged by solar charge controller, and the electric energy converted from the light energy is stored.

At night, the battery pack provides power to the inverter. The DC power is converted into AC power via inverter to power the home appliances via PDS. The discharge of the battery pack is controlled by the solar inverter to ensure the normal use of the battery.

The Solar system should also be equipped with limited load protection and lightning protection devices to protect the system equipment from over-load operation and lightning strikes, and maintain the safe use of the system equipment.
