How does a storage battery for a photovoltaic system work?

A storage battery for a photovoltaic system works as a kind of warehouse for the solar energy produced by photovoltaic panels. The system works by accumulating excess energy during the day, when energy production is greater than usage, to be used during the night or at times when solar radiation is low. The battery is composed of one or more cells that store electrical energy in the form of electricity. These cells are controlled by a battery management system that monitors the amount of energy accumulated and distributes it to the system when needed. The operation of the storage battery is very simple. During the day, when energy production is greater than usage, the battery accumulates excess energy. When energy production drops, such as during the night or at times when solar radiation is low, the battery provides the accumulated energy to the system. This way, the system can continue to operate autonomously, without depending on the national power grid. Additionally, the storage battery is equipped with safety systems that guarantee the protection of the system and the battery itself. For example, the battery management system can deactivate the battery in case of overload or malfunction, ensuring the safety of the system and the user. In summary, a storage battery for a photovoltaic system is a convenient and sustainable solution for electricity production. With the use of the storage battery, the system can operate autonomously, without depending on the national power grid and ensuring continuous production of clean and sustainable energy.
