I recently had my EP12 Fox ESS battery installed by Suns Power, and I couldn’t be happier with the experience. The installation took place on a very rainy day and initially looked like it might have to be rained off, but Rob pushed on and managed to get everything completed regardless, which I really appreciated. The inverter and battery were installed exactly where I requested, and the team took the time to explain everything clearly. They also pointed out that my existing EV car charger could ideally have been installed on a separate board, which I found helpful and honest advice. The app setup and overall installation went smoothly, and John has been superb from start to finish. He explained the install process in detail and showed me how to maximise my usage alongside my existing system. The Fox ESS system is highly intuitive and very easy to use. The app is clear and user-friendly, making it simple to monitor energy. John ensured my system was working and up to date even chasing Fox to push an update through. Overall, a very professional, knowledgeable, and friendly team. I would highly recommend Suns Power to anyone considering battery storage or solar upgrades.

Highly Recommend Suns Power for Solar Installation! ☀️ I recently had a full solar system and battery setup installed by Suns Power, and I couldn’t be happier with the experience. The system includes 11 Aiko panels, a FoxESS inverter, and a 10kWh battery an impressive combination that’s already saving me around £4 a day by making my home largely self-sufficient. John from Suns Power was exceptional throughout the process. He provided a range of options with different brands and configurations, along with a clear, professional proposal outlining the financial savings and carbon offset. His knowledge and transparency made it easy to choose the right setup. The installation was quick and seamless completed in just one day! By the end of it, I was already generating solar power. The FoxESS system John recommended works flawlessly, giving me easy access and control over both the battery and inverter. John’s professionalism, thorough assessments, and willingness to answer all my questions made the entire experience smooth and reassuring. I highly recommend Suns Power to anyone considering solar energy.

We recently had a new FoxESS battery and inverter installed by Suns Power. Our primary reason for getting the system was to charge the batteries overnight during off peak/night rate and then to discharge over the day. From the very first phone call, John was professional and knowledgeable. They provided a detailed quote and answered all of our questions without any pressure. The installation itself was seamless. The technicians, arrived on time, was incredibly professional, and kept the work area spotless. They even took the time to explain how the new system works and how to monitor it on the app. The system has been running for a few weeks now, and it has exceeded our expectations. Our daily bill has dropped from around £5.50 per day to around £1.50 per day. We are so happy with the entire process and the final result. We would highly recommend John at Suns Power to anyone considering a home battery and inverter installation.

I had been searching for a while for the right battery installer as friends had some horror stories, fortunately when speaking with John you could tell he cared and was passionate about getting the right installation in place. Need less to say the installation went very smooth and the Installers were fantastic, even took the rubbish with them. Support has extended past the install ensuring I am on the best tariff for my needs. I would 100% recommend Suns Power.

Very dishonest and unreliable company. He sent for installation a guy who was not properly qualified and certified to do the job. After repeated chasing, he provided the installation certificate by a contractor who never did the job nor ever had been to my property. After taking the full money he never responded and never helped with setting up the App on mobile as was promissed by him. Taking all three ( Owner of Suns Power, Jay who had installed the unit and the contractor who issued a fake certificate) to court and the legal consequences would be imprisionment to all three. My home is at risk because the installation was done by someone who was never qualified to do the job. Also despite of repeated requests, they have not sent me the declaration signed which is needed by my energy provider. This is one of the companies who run away after they get their money. Anyway they will face the consequences in Court.

Suns power ltd I strongly recommend for…

Suns power ltd I strongly recommend for other customers to use. Their team are incredibly knowledgable, helpful and professional. The equipment is high end product and from just 24hrs the system is significantly reducing my consumption to put money back in my pocket. The install is 5* and does what it says on the tin. I’m a hard one to please at times and this supplier has provided one happy customer. Thank you again

Genuinely impressed with Suns Power

We’ve been genuinely impressed with Suns Power from start to finish. John was excellent throughout the process. Extremely knowledgeable, happy to answer every question, and clearly very experienced in what he does. I work in a similar technical industry myself, so I went into this with fairly high expectations. I’m pleased to say they were fully met, and in many ways exceeded. The installation was neat and professional, and everything was clearly explained so we understood exactly how the system would perform and how to get the most from it. Since having the battery storage installed, we’ve already seen a real difference. Even in winter, we saved just over £200 last month simply by offsetting our electricity usage and making better use of cheaper tariff periods. Overall, a very positive experience and I would confidently recommend Suns Power to others considering battery storage.

A first class installation.

A first class installation by Rob who couldn't have been more helpful. Having seen some pretty awful installations posted on Facebook, I was somewhat nervous but John Sent me a number of photos of installations completed by the company so I was re- assured. Thoroughly recommended.

Excellent Suns Power

Suns Power were excellent throughout my purchase and installation. There was an unexpected fault (not their fault) but John went above and beyond to get it sorted. The aftercare has also been brilliant with remote monitoring and support to get the most out of my system.

I’ve had a good 6 weeks now, to monitor the performance of my new installation. Firstly, I was impressed by the customer service I received when I was looking to get quotations for an inverter and batteries to complement my already installed solar panels. John was very knowledgeable and answered the numerous questions that I asked him. He also matched the price I had obtained from another company, which tipped the balance in favour of me placing my order for an Hanchu 5kW inverter and 2 Hanchu 9.4 kWh batteries. I was very pleased with the installation in my garage, which was completed quickly and with no mess, close to the consumer unit (see photos on Suns Power FB post on 23 November). John has also provided excellent after sales service, answering more questions about the Hanchu app, and helping me better understand how my set-up functions. John recommended the Good Energy EV tariff, even though I don’t have an electric car, as the off peak tariff is only 6.60p/kWh from 12am-5am, which is when I set my batteries to recharge. Looking at my electricity costs, they have so far averaged out under £1.00 per day. This should reduce further when solar generation is more consistent (May-September) thereby allowing me to top-up my batteries on a daily basis. I’m pleased that I chose Suns Power, being impressed by both their service and price, and would strongly recommend getting a quotation from them.
