Description

Powerwall 3 puts the battery and the solar inverter in one sealed unit, so there is less kit on your wall and fewer parts to go wrong. Each Powerwall 3 stores 13.5kWh, enough to run a typical home through the evening and overnight, and you can add up to three expansion units for 54kWh in total. We handle everything: survey, design, installation, commissioning and the paperwork.

What’s Included

  • Tesla Powerwall 3 (13.5kWh usable) with built-in hybrid inverter, single phase
  • Optional Powerwall 3 expansion units, 13.5kWh each (up to three)
  • Optional Tesla Gateway for automatic whole-home backup in a power cut
  • Full installation and commissioning by our in-house team
  • Set-up in the Tesla app, so you can watch your solar, battery and grid use live
  • MCS certification documents

Why Choose Powerwall 3

  • All-in-one: battery and solar inverter in one IP67-rated unit, suitable for indoor or outdoor fitting
  • Works with new or existing solar panels, or on its own to charge from cheap overnight tariffs
  • Expandable from 13.5kWh to 54kWh as your needs change
  • Tesla manufacturer warranty

With or Without the Gateway?

Without the Gateway, Powerwall 3 stores and uses your energy day to day. With the Gateway, your home switches to battery power automatically if the grid goes down. We’ll talk you through which suits your home at survey.
