Our verdict

Is a Sofar battery right for you?

A budget battery with a full 10-year warranty for typical use. Specs are ordinary, so it's mainly about price.

Rated 6.8/10, #8 of 9 brands we rate for batteries.

A good fit if

  • You have a Sofar hybrid and want a matched battery

Maybe look elsewhere if

  • You want room to grow past 20 kWh

What we like

  • Full-term warranty

    Covers the full 10 years for typical use.

Worth weighing up

  • Limited size

    BTS tops out around 20 kWh.

Questions to ask your installer

  1. 1How much of my evening use will this cover?
  2. 2Does it include backup in a blackout, and for which circuits?
  3. 3Can I see the warranty document, including the throughput limit?

A good installer will be glad you asked, whichever brand you choose.
