Battery Storage
Systems
A battery energy storage system (BESS) is a rechargeable battery that stores energy — from solar or the grid — so you can use it exactly when you need it.
Take solar savings a step further.
Many homeowners install solar to reduce their bills — a battery lets you take that a step further, storing your own surplus energy for use any time. SR2 Renewables is fully qualified to supply and install a range of battery brands, so you get the right fit rather than a one-size-fits-all product. Based in Chester, we cover Chester, North Wales and the Wirral.
Use your power when you need it.
Reduce Bills Further
Store what you generate instead of exporting it, and use it when you actually need it.
Backup Power
Many systems keep essentials running during a power cut with the right backup setup.
