How a home battery works

  1. 01

    Charge from solar or the grid

    Your battery fills up from spare solar power, or from the grid when electricity is cheaper.

  2. 02

    Store energy for later

    Instead of exporting everything or buying at peak times, you keep energy in reserve.

  3. 03

    Power your evenings

    Stored energy runs your home when the sun goes down or prices go up.

  4. 04

    Smart control

    Many batteries can be set to charge and discharge automatically around your tariff.

Signs it’s a good fit

  • You have solar, or are getting it
  • You are on, or could switch to, a time-of-use tariff
  • You use most electricity in the evening
  • There is a suitable spot for the unit

What affects your quote

Battery storage: your questions answered

Still unsure? Our guides and system size tool can help.

Do I need solar panels to have a battery?

No. A battery can charge from the grid at off-peak times and power your home at peak times, although it is usually most useful alongside solar.

How big a battery do I need?

It depends on how much electricity you use in the evening and overnight. Our system size tool gives you a guide in about a minute.

Will a battery keep my power on in a power cut?

Only some systems offer backup power, and it usually needs extra equipment. Tell your installer if this matters to you.

Where does the battery go?

Often in a garage, utility room or on an outside wall, depending on the model and the installer’s survey.
