Why Choose a Home Battery?
Use More of Your Own Solar Energy – Even After Dark
A battery energy storage system (BESS) lets you store excess solar power during the day and use it when energy prices peak, like in the evening or during winter.
It’s one of the smartest ways to lower your bills, protect against power cuts, and take control of your home energy.
In towns like Tonbridge, Sevenoaks, Brighton and Guildford, more and more homeowners are choosing battery storage as energy prices rise and grid reliability falls.

How It Works – Store Solar for When You Need It
Capture Daylight. Use It After Dark.
During the day, your solar panels generate electricity, and anything you don’t use is stored in your home battery.
In the evening, your battery kicks in, powering your home with clean, low-cost energy, even when the sun goes down.
Smart systems like Tesla Powerwall and SigEnergy can even charge up when grid prices are low, and discharge when they’re high, helping you save even more.

Smart App Control & Energy Management
Take Control of Your Energy, Wherever You Are
With the Tesla app or Sigenergy’s mySigen app, you can track your energy use in real time, schedule appliances, and monitor your system’s performance, all from your phone.
The smart software learns your habits, forecasts sunlight, and checks electricity prices to automatically charge or discharge your battery at the best time.
No technical know-how needed, just simple, intelligent energy management that works for your home.

Our expert Tesla and Sigenergy battery installation team, based at our HQ in Tonbridge, Kent, are extremely knowledgeable and here to help.
What brands do you install?
We install Tesla Powerwall and SigEnergy SigenStor systems, both are premium, high-performance batteries designed for UK homes.
Can I use solar power at night?
Yes. A battery stores excess energy during the day so you can use it in the evening, or even during a power cut.
Is it worth getting a battery without solar panels?
It can be, especially if you’re on a time-of-use tariff. Some customers charge their battery from the grid at night, then use that energy during the day when prices are higher.
How long does installation take?
Most battery installations take less than one day. We’ll handle everything, from system design to setup and app connection.
Do you offer support after installation?
Yes. Our local team is on hand for ongoing support, and your system is backed by a full warranty for long-term peace of mind.
