The latest generation of Tesla’s home battery – Powerwall 3 – is now available in the UK.
Powerwall 3 can power most European homes with a single unit, enabling savings through storing excess solar energy generated during the day for use at night during peak pricing hours. By using self-consumption mode to store excess solar for use at night, Tesla says that UK customers can reduce their reliance on the electricity grid by 90%.
Further savings can be unlocked through time-based control mode. This feature allows owners on a utility rate plan that varies by time of day to set their Powerwall to maximise their savings, charging from the grid when prices are low, and using cheaper energy stored in Powerwall to power their home when electricity prices are high. On average, owners can save up to £1,450/yr* powering their home with Powerwall 3 paired with solar*.
Powerwall 3 also has the added benefit of backup protection. It automatically detects outages and becomes the home’s energy source when the grid goes down. When severe weather is forecast, the Storm Watch feature will automatically charge Powerwall 3 to its maximum capacity to prepare for an outage, keeping the house and appliances powered.
Powerwall 3 has more than double the power output of Powerwall 2, providing the flexibility to power any sized home. The inverter can output between 3.68 kW to 11.04 kW throughout Europe, enabling further savings by powering a greater variety of appliances.
With a built-in solar inverter, Powerwall 3 has greater power efficiency, creates a cleaner-looking install with fewer boxes on the wall and reduces the need for a customer to purchase a third-party inverter.

*Estimates are based on the average Powerwall customer in the UK with 6kw of solar and one Powerwall 3, assuming typical consumption and PV production of the climate region (approximately 6,300 kWh and 6,200 kWh , respectively) and actual utility rates (£0.24/kWh + fixed charges before adding PV+PW). Actual savings depend on location and specific energy demands per household. Future electric utility rates are estimates only and may vary.
Energy storage is a key topic at next week’s InstallerSHOW 2024, running 25 to 27 June at the NEC. It is free to attend, including parking. Register for FREE tickets here: installer-2024-splash.reg.buzz
