Energy firms have suspended all non-essential work as they brace for a potential shortage in engineers, caused by staff sickness and self-isolation.

Electricity networks across Britain have implemented emergency pandemic strategies... As people follow the Government’s instructions to work from home and stay indoors, they are more dependent on the electricity supply than ever before.

How does the Tesla Powerwall work?

Tesla Powerwall utilises a rechargeable lithium-ion battery, storing electricity to be used when needed in the event of a grid failure and also providing solar power overnight.

How will a Tesla Powerwall keep me safe from power cuts?

You decide what percentage of the battery is reserved for protection against grid failure, and this percentage is always held in reserve until a power cut. The remaining percentage of the battery is available for solar power to be used overnight.

How much energy can a Tesla Powerwall store?

Tesla Powerwall can store up to 13.5kWh of energy – that’s enough to supply a typical home’s power usage for a whole day or more. 

Is having a Tesla Powerwall high maintenance?

The beauty of the Powerwall is that it requires no maintenance - the fully automatic system means there’s no need for you to monitor it. Tesla closely monitors batteries to catch failures before they happen.

They were always at the other end of the phone and normally responded to emails within a few hours. They were also brilliant with the recommended COVID-19 Steps from the government.

Customer in Weybridge, February 2020

Glenn is a very knowledgeable person and the only person to fully survey the property and think about where the cables would go, look at the roof etc before coming up with a bespoke system for us. He knows his stuff. I would highly recommend.
