Redhill Services offers expert installation and support across domestic and business properties, making clean, reliable energy more accessible than ever.
What is Tesla Powerwall 2?
The Tesla Powerwall 2 is a fully integrated energy storage solution that works alongside solar panels or on its own to store electricity. You can use stored energy to power your home or business day and night, even when the grid goes down. It helps you reduce your reliance on expensive peak-time electricity and makes the most of your solar system by capturing excess generation. Each unit is compact, quiet, and designed for long-lasting performance, offering a strong return on investment for homeowners and businesses alike.
How it works
Powerwall 2 stores excess solar energy produced during the day instead of exporting it back to the grid at low rates. You can then use this stored power in the evening or during periods when your panels aren’t generating enough. If you don’t have solar, you can also store cheaper off-peak electricity from the grid to use when rates are higher. It automatically switches between sources to ensure your property always has power at the lowest possible cost. In the event of an outage, Powerwall instantly provides backup power, keeping your essential appliances and systems running without interruption.
Key uses for homes and businesses
