When we recommend a Powerwall

Powerwall is a single, self-contained battery unit rather than a modular stack. Each unit has a fixed capacity, and more capacity means adding another unit.

It suits households that want a well-known product with strong app control and a whole-home backup arrangement, and whose usage lines up with the capacity of one or two units.

We compare it honestly against modular systems such as Anker SOLIX and Sigenergy, and recommend whichever fits your home and tariff best.

  • "Ben from SolarFX and his team have done a great job for us. Kept us in the loop at all stages, and Ben has been really supportive following the install with support, set up and managing the new system. During the recent sunny period our average cost per day for electricity was 60p. Would strongly recommend SolarFX."

Is a Powerwall right for your home?

A good fit when

  • Your usage suits one or two fixed-size units
  • Whole-home backup is a priority
  • You want strong app control and a widely recognised product

Worth comparing when

  • You want to start small and add capacity gradually — a modular battery may suit better
  • Budget per kWh of storage is the main driver

Tesla Powerwall questions we get asked

How much storage does a Powerwall have?

Each unit has a fixed usable capacity. We confirm the current specification and how many units you would need in your written quotation.

Can a Powerwall run my house in a power cut?

With a backup arrangement, yes. What it can run and for how long depends on your loads, which we work through at design stage.

Can I add a Powerwall to my existing solar?

Often, yes. We check your existing inverter and supply at survey and recommend the cleanest way to connect it.
