Tesla Powerwall

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.
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.

The whole work was completed within the arranged schedule, to a really high standard, and to a fair and reasonable cost. I would use Belectrix again.”

William Daniel (Leighton Buzzard), Installed: 7.4kW Solar + Powerw

“I had 2 Tesla PowerWalls installed by Yury in December 2023.
Installed very neatly and professionally and, having used them for 3 months now I can report that I am truly delighted with them.
I use Octopus Agile tariff to import power from the grid as well as my solar panels and I am saving about £200 per month on my electricity bill, compared to EDF with no PowerWalls.”

Richard Hudson (Hemel Hampstead), Installed: 2x Tesla Powerwalls

“Yury and his team recently installed a hybrid solar Inverter and batteries, as well as a zappi charger. Really neat job – very tidy, everything working well. Charging up on octopus go, discharging during the day. Very pleased with everything and it was a pleasure to have Yury and his team in my house”

Matthew Durkin (St Albans), Installed: 5kW Solar + 20kWh Fox Batteries

“Yury is a gentleman and all his colleagues are very professional. He has installed a 8kwh system with a powerwall 2 battery. I own 2 EV motors so my bills were shy of £5k a year on electricity. My bills have been hammered down. Even in winter the system held out well. My first March with the system has been epic. Bring on the summer. Highly appreciated and recommended.”

Bharat Vekaria (Bovington), Installed: 8kW Solar + Powerwall

“Excellent service, neat and tidy install, made integrating solar energy into our lives really straight forward. Would definitely recommend!”

Cameron Ford (Cambridge), Installed: 4kW SolarEdge system
