This battery is part of a PV system, which means it is designed to work with residential PV systems. It has the capability of storing electricity that is generated at home using solar energy. Solar energy is harnessed using PV panels which generate direct current power (DC). The energy is best used during the night or when the weather is not so sunny. The batteries that come with this system utilize either lithium-ion or lead-acid batteries as they are best suited for PVs. These batteries serve the purpose of helping in storing the solar energy so it can be used later. This allows homeowners to lower their dependence on the grid and gain more control over the energy they consume
