Premium home storage
Whole‑home backup
Keep the lights, Wi‑Fi and essential appliances running. Powerwall 3 can start heavy loads with 185 A LRA, so big motors like heat pumps and well pumps are covered.
Serious power in a small footprint
Up to 11.04 kW continuous output at 230 V from a single unit for confident whole‑home support.
Built‑in solar inverter
Connect solar straight into the battery for high efficiency and a tidy installation. It can also work with most existing solar systems.
Scales with your needs
Add Powerwall 3 Expansion units, each adding 13.5 kWh. With multiple Powerwalls and Expansions you can reach up to 44 kW AC and 94.5 kWh of storage for extended backup. Ideal for larger homes and businesses in and around Leicestershire.

With solar
Your panels power the home first, then charge Powerwall 3. Stored energy runs your home after dark or during outages. The Tesla app alerts you if the grid goes down.
Without solar
On time‑of‑use tariffs, Powerwall can charge when electricity is cheaper and discharge when it’s expensive to reduce costs automatically.
During an outage
Powerwall 3 takes over in milliseconds, delivering continuous backup with that 185 A LRA start capability for heavy loads.
