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.
[pdf] “Storage” refers to technologies that can capture electricity, store it as another form of energy (chemical, thermal, mechanical), and then release it for use when it is needed. Lithium-ion batteriesare one such te.
[pdf] Think of your DC motor as the marathon runner of your energy storage system—it needs a steady pace (current) to go the distance without burning out. The rated working current is its "sweet spot": the maximum continuous current it can handle while maintaining optimal performance and longevity.
