The Tesla Powerwall 2 is the company’s answer to power backup. It’s a 13.5kWh lithium-ion battery storage system, designed to help your keep your essentials running during a powercut, without any downtime, when paired with Tesla’s Backup Gateway.
In this installation, we installed TWO Tesla Powerwall 2’s, along with a very large solar array.
Having a large amount of storage will set you up to benefit from the ‘time of day’ charging that Smart Meters will bring, meaning you can charge for free from your solar, or from the grid at cheap times further increasing your financial benefits.
With up to 13.5kWh of storage per battery, and capable of delivering 5kW of power continuously and up to 7kW for 10 second periods, the Powerwall is extremely good value as the price per kWh of storage
The Powerwall is the most popular battery on the UK market.
