Tesla Powerpack certified installers

There are many options when it comes to energy storage. Batteries can offer over 30 potential revenue streams and which is best for you depends on many factors. 

As one of only a handful of UK installers that are Tesla Powerpack certified, you can feel comfortable that we’re the experts in designing, installing and maintaining energy storage systems.  

An introduction to commercial energy storage

Commercial energy storage is a vital player in the new smart grid era. An increasing amount of renewable energy is being generated at sites across the UK.

Renewable energy generation is intermittment, generating more when its sunny or windy. Because both end users and the grid need energy at different times, energy storage is needed to ensure a smooth supply. Batteries can play a part here on many scales, saving on energy costs for the end user and reducing strain on the grid. For example, they can:

  • store excess energy generated by on-site solar PV, then make this energy available at times of peak demand
  • import energy when its cheap and then provide this energy on-site at peak times (time of use load shifting)
  • provide additional income through grid services, essentially being called upon to provide energy to the grid when needed

Everything from SunGift’s communication, planning and problem solving is a testament to their experience and professional work ethic. We chose SunGift because of their impressive proposal for the project, which went above and beyond our expectations. The quality of their work did not disappoint, and I’m incredibly impressed with their installation. I look forward to working with SunGift in the future.

Your site

your existing infrastructure and how much the local grid can accommodate will affect whether you can have a battery, what size, and the costs involved. We can undertake initial enquiries on your behalf, along with site surveys, to ascertain what’s possible.
