Its working principle is that when the photovoltaic components generate excess power during the day, the surplus electrical energy is converted into chemical energy and stored in the internal battery pack; and when night falls or encounters rainy weather, the photovoltaic system generates insufficient power, and then the stored electrical energy is released to provide a stable power supply for the load.
