When you think of Tesla, what’s the first thing that comes to mind? Probably its state-of-the-art electric vehicles. However, Tesla is a tech giant with fingers in many pies, including the solar battery market.
The Tesla Powerwall 2 is a market-leading home battery storage solution and the most popular battery available in the UK right now. It has some of the best specifications and is the only home battery product on the market to offer a liquid thermal management system.
Tesla Powerwall 2
Powerwall 2 is a lithium-ion battery with a 13.5kWh energy capacity that comes with floor and wall mounting options and can be installed indoors or outdoors. Suitable for homes and small to medium-sized businesses, the Powerwall 2 is modern and compact to complement various property styles and stores energy from solar or the grid during the day for use at night or when the sun refuses to shine.
The Tesla Powerwall 2 connects to your home’s electrics and is designed to be used with a solar PV system. When there is no energy available from your PV system, and you use up all the energy stored by the Powerwall, you can pull electricity directly from the grid. As the Powerwall can work without solar panels and take charge from the grid, it also appeals to homeowners who live in areas prone to power cuts.
Tesla’s Powerwall 2 features a liquid thermal management system that enables continuous operation in a wide range of temperatures from -20°C to +50°C and is compatible with the Tesla app, which lets you monitor your home’s energy production and consumption in real-time. Powerwall 2 also provides your home with backup power to allow you to continue using your electric appliances during a power cut.
You can install up to 10 Powerwall units to increase your storage, further reduce your reliance on the grid and make your home even more self-sufficient.

Tesla Powerwall 2 Reviews
Powerwall 2 is said to be the best and most popular home battery system on the market, to the point where Tesla continues to struggle to keep up with demand. However, Tesla does not currently offer Powerwall 2 in the UK, so you have to find a third party that does.
In the US, Tesla is no longer taking orders for the Powerwall 2 without solar panels. That means customers have to buy the Powerwall and a new solar panel system because Tesla now sells them as an integrated product. But, here in the UK, you can find local suppliers and installers who offer Powerwall 2 without you needing to purchase solar panels.
