Frequently Asked Questions

Prices start from £8,000 + VAT supplied and installed (this includes the gateway).

If you are in the unfortunate position of a power cut, a Tesla Powerwall and solar can offer power for when this happens.

In an outage, the Tesla Powerwall is capable of lasting up to 1 day 17 hours and 15 minutes.

The majority of homeowners will typically charge and discharge their batteries every day. However, it isn’t necessary to charge it daily. This depends on how much stored electricity you’re anticipating to use. Another factor to consider is the size of your household. A larger house that uses a significant number of electricity on a daily basis is going to need to charge their battery more frequently than a smaller family home that doesn’t use nearly as much.

Whilst many homes around you may have power cuts that result in no power for hours or even days at a time, the Tesla Powerwall is a reliable home device that ensures your home can continue to run smoothly at night-time through solar energy that gets stored into the Powerwall during the day.

The number of Tesla batteries required to power your home depends on the amount of time you intend on solely powering your home through Tesla battery storage.

On average, if your energy usage is around 9kwh a day with a 120 square metre house size then 1 – Tesla Powerwall battery is recommended to power your home. If your household’s electricity usage and house size are significantly more, you may require 2 + Tesla Powerwalls in order to completely power your home. However, Powerwalls are not designed to fuel homes for days on end they are designed as a backup to a solar system when daylight has passed, and your solar system is no longer absorbing the sunlight.

Some Tesla batteries take longer than others and this depends on your charging output as well as the powerwalls lowest input. This can, therefore, vary the number of hours it takes for your Powerwall to charge.

Powerwall needs an Internet connection (over wired Ethernet or your home Wi-Fi) or a cellular connection to receive software updates and to communicate with the Tesla mobile app for energy monitoring. A reliable connection is required to provide new product features over time. If its connection is temporarily lost, Powerwall can continue to operate with its most recent settings, but it should not be installed in a location without Internet or cellular service.
