AC coupled can charge from various sources, like cheap grid power, and offers more installation flexibility. Whichever you pick, with a trusted installer like London Charging, it’ll pair nicely with your solar setup.

Solar with a battery
- Stores and utilises more of your solar energy.
- Less reliance on the Grid
- Access to greener energy, even at night
- Eligibility for the Smart Energy Guarantee (SEG) – they pay you for excess energy!
Solar without a Battery
- You only utilise 20-40% of the solar energy produced*
- Energy bills incurred during nighttime or rainy winter days
Your battery stores electricity for later. Sometimes you generate more solar power than you use, especially if everyone’s out. On not-so-sunny days, instead of relying on the grid, you've got stored energy to use
Of course! Our site surveys for battery installations are 100% complimentary.
Duration-wise, a full-charged battery like the Tesla Powerwall 2 might power your home for over a day. Lifespan-wise, after thousands of charges, batteries might hold a bit less power, but they come with around a 10-year warranty. And in our experience, they usually outlive that by a good bit.
A 10-year warranty on the product. A 25-year guarantee for performance. A decade-long warranty from battery manufacturers.A warranty for workmanship backed by insurance. A life cycle guarantee ranging from 6,000 to 10,000 cycles.
Home batteries come in different sizes. UK households typically use 8-10 kWh daily. Batteries range from smaller 2.5-5 kWh units to larger 13-15 kWh ones. It's a mix of matching your nightly usage with what your solar system produces.
