Photovoltaic system——Battery

A battery is a device that stores electricity in a photovoltaic power generation system. At present, there are four types of lead-acid maintenance-free batteries, ordinary lead-acid batteries, gel batteries and alkaline nickel-cadmium batteries, and lead-acid maintenance-free batteries and gel batteries are widely used.

Working principle: During the daytime, sunlight shines on the photovoltaic modules to generate DC voltage, convert the light energy into electrical energy, and then transmit it to the controller. After the overcharge protection of the controller, the electricity from the photovoltaic modules is transported to the battery for storage. , for use when needed.
