In electricity, off-grid can be stand-alone power systems or mini-grids typically to provide a smaller community with electricity. In this system, the harvested solar energy will be used directly and/or by charging.

This system is designed with a high intelligence program to take care of battery charge and regulate the power supply by converting DC to AC power for optimum usage. It combines three different energies (solar, battery power, and the grid) that will act in an uninterrupted power supply and in the load maintenance with any one of the powers from the three sources.

The Off-grid PV system will be well applied in domestic sectors, hospitals, data centers, and also in educational laboratories.
