Energy Storage

Engenius are proud installers of Tesla’s Powerwall – market-leading home & business battery storage solution.

Tesla Powerwall is a fully-integrated AC battery system for residential or light commercial use. Its rechargeable lithium-ion battery pack provides energy storage for solar self-consumption and time-based control. The revolutionary compact design achieves market-leading energy density, enabling owners to quickly realise the benefits of reliable, clean power.

We at Engenius will ensure the quality of the installation will match the quality of the technology. If you’re interested in our battery installation services, call us on 01983 247981 (9am-5pm Monday-Friday) or use our contact form to quickly and easily get in touch or request a callback.

With a capacity of 13.5kWh, a standalone Powerwall will reduce your energy bills, improve your home’s energy efficiency, and help you meet carbon reduction goals. In addition to savings & RoI, the Powerwall will continue providing energy in the event of powercuts – storing a user-defined portion of power. The Powerwall’s Stormwatch service adds additional energy security, automatically storing power in the time leading up to large storms.

We recommend this battery for a number of reasons – first and foremost, it is quite simply the best, and most cost effective battery available on the market. The energy density is unprecedented, the warranty is market leading, the useable capacity (100% Depth of Discharge) is , and it is still one of the few batteries with internal temperature controls to allow mounting outside. That said, we aren’t beholden to just Tesla and we are able to install all home batteries available – give us a ring (01983 247981) and we can discuss your requirements.
