The system is composed of PV module, Solar Off grid inverter, MPPT charge controller and Battery pack. Solar Off grid inverter is core device of PV power sysem, it converts DC power produced by solar panels to AC power to provide electric energy for applications. MPPT charge controller charge the solar electricity into batteries. When solar energy is not enough for loads, or at night, the battery pack will be discharge to replenish energy for loads.
