Tesla Powerwall 2
Store Energy
Powerwall reduces your reliance on the grid by storing your solar energy for use when the sun isn’t shining. Use Powerwall alone or combine it with other Tesla products to save money, reduce your carbon footprint and prepare your home for power outages.
24/7 Backup Protection
Powerwall is a battery that stores energy, detects outages and automatically becomes your home’s energy source when the grid goes down. Unlike generators, Powerwall keeps your lights on and phones charged without upkeep, fuel or noise. Pair with solar and recharge with sunlight to keep your appliances running for days.
Power Your Home
With easy installation and a minimalist design, Powerwall complements a variety of home styles. The compact, all-in-one construction features versatile mounting options for indoor or outdoor spaces.
With the Tesla app, you can monitor your home’s energy production and consumption in real time. Set your preferences to optimise for energy independence, outage protection or savings. With instant alerts and remote access, you can control your system from anywhere.

NEW FOR OCTOBER 2020 – Tesla are now offering an energy tariff to buy electricity from them and an export tariff for customers with solar PV and a Powerwall. Rates to buy electricity are as low as 8p per unit and to export as high as 11p per unit. These rates are a huge challenge to Big 6 prices!
