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.

Independent & qualified

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.

Why add storage

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.

No solar yet? Charge from the grid on cheap overnight tariffs and use it during the day.

Smart Monitoring

Track generation, storage and usage in real time from an app on your phone.

Frequently asked questions

Battery storage questions, answered.

Do I need a battery with my solar system?
No — solar works perfectly well on its own. A battery simply lets you use the power you generate during the day, in the evening too, maximising your savings.
Can I benefit from a battery without solar?
Yes — you can charge a battery from the grid during cheaper off-peak hours and use it when electricity rates are higher.
Will a battery give me backup power in a cut?
Many systems include emergency power supply (EPS) features that keep essential circuits running during an outage — ask us about EPS-enabled batteries.
How much space does a battery take up?
Most home batteries are compact, wall or floor-mounted units that fit easily into a garage or utility space.
Can I add a battery to my existing solar system?
Yes — batteries can be retrofitted to almost any existing solar PV system.
