Tesla Powerwall 3 Installer in Bedford
The highly anticipated Powerwall 3, released into the UK in October 2024, let's take a look at what this Battery has to offer.
Powerwall 3 is a fully integrated solar and battery system designed to accelerate the world’s transition to sustainable energy. Powerwall 3 can store solar or grid energy for later use when the sun goes down or when the electricity prices are high; lowering their electricity bills, reducing their reliance on the grid, and power their homes during a grid outage. Once installed, customers can manage their home energy system using the Tesla App and customize system behaviour to meet their energy goals.
Powerwall 3 achieves this by supporting up to 20 kW DC of solar and providing 11.04 kW AC of continuous power per unit. It has the ability to store up to 13.5 kWh of energy and start heavy loads rated up to 185 A LRA, meaning a single Powerwall 3 can support the power needs of most homes. Powerwall 3 is designed for fast and efficient installations, modular system expansion, and simple connection to any electrical service.
