SolaX Battery Storage Cornwall.
SolaX's retrofit inverters are built to bolt onto an existing solar system without replacing what's already on your roof. That's a genuine option if you installed solar years ago and want to add storage now. We fit it as part of a fully surveyed, MCS certified installation, sized around your home's actual usage rather than a one-size-fits-all package.
Residential batteries also qualify for 0% VAT until 31 March 2027: see full details
A proven battery, built to last.
Established UK Track Record
SolaX Power is one of the most widely installed battery brands in the UK, and that track record counts for a lot. A large installed base means a mature product, a well-established parts and support network, and an installer community, including us, with years of hands-on experience fitting and maintaining their systems.
SolaX pairs its battery with an X1 or X3 hybrid inverter, which converts stored power into usable electricity for your home. Because it's a separate, proven inverter line, it's also a strong option if you're adding storage to solar you already have from another manufacturer.
Modular, Widely Compatible
Their Triple Power battery is modular, so you can start with the capacity you need now and add further battery blocks later if your usage grows, without replacing what you've already got. It pairs with SolaX's X1 and X3 Hybrid inverters, and, importantly for retrofits, is compatible with a wide range of existing solar panel brands and inverters, not just SolaX's own equipment. That makes it a strong option if you already have solar installed from another manufacturer and want to add storage without disturbing what's already on your roof.
10-Year Warranty
SolaX backs its batteries with a 10-year warranty, and because the brand is so widely used across Cornwall and the wider UK, replacement parts and support are rarely an issue if anything needs attention years down the line, a real consideration when a battery is meant to keep working for a decade or more.
Fully Certified Installation
Because SolaX's retrofit range is compatible with any brand of existing single-phase inverter, it's often the most cost-effective route to battery storage if you already have panels installed and just want to stop exporting your surplus for pennies.

I cannot recommend Holloway Electrical highly enough. From the planning of our solar and battery installations through to the final commissioning Jamie's took care of everything. Organised other trades to assist, explained everything that was going on and completed the job on time as promised to an exceptional standard, I could not be happier.
We experienced a very friendly and helpful service from Jamie with our new kitchen electrics. We would highly recommend his services.
We are so pleased with the work that Jamie completed for us today, supplying power to our apartment garage and installing sockets and EV charger. The quality of the work is outstanding. I highly recommend Holloway Electrical Ltd, definitely our electrical professional for all future requirements!
Hi Jamie, Kieran did a great job and we are both very pleased with it. Thank you very much. I would like to discuss with you the electrical box in the kitchen which will need to be replaced. PEH
A lovely local company to deal with. Efficient and left everything clean and tidy. Highly recommend.
Great communication, excellent service, great price, 100% recommend.
We had several quotes from Electricians to install our EV charger which varied dramatically. Jamie’s quote was by far the most reasonable and he was the only one who bothered to come to our home and look at the charger etc. before taking on the job. He arrived on the agreed date of installation and was personable, efficient and tidy. I would have no hesitation in recommending Jamie and would be happy to call on his services again in the future.
