A Battery Energy Storage System (BESS) is an advanced technological solution that allows energy to be stored in a variety of ways for later use. Lithium-ion battery energy storage systems, in particular, use rechargeable batteries to store energy generated by solar panels or provided by the grid, and then provide it when needed. The benefits of battery energy storage include increased energy efficiency, conservation and sustainability by enabling renewable energy sources and reducing consumption. As the energy transition from fossil fuels to renewables accelerates, battery storage systems are becoming an increasingly common feature of everyday life.

The supply of solar and wind energy can fluctuate, so battery storage systems are essential to "eliminate" this flow to provide a continuous energy supply 24/7 when needed, windy or sunny. In addition to the obvious environmental benefits of battery storage systems, battery storage systems offer some obvious benefits to home users and businesses. Energy storage can help users save costs by storing low-cost energy and supplying it during peak periods when electricity prices are higher.
