Excellent knowledge and service. Ron responded to my initial query really quickly (same day), and confirmed that he could add extra panels and battery to my existing GivEnergy setup - something I’d been told by other installers wouldn’t be possible. Two weeks later (!), scaffolding was up and Ron and his team were on site to fit the extra 5 panels and two more GivEnergy batteries. I now have a truly optimised system, which has made the most of the south facing roof space I have, without having to start again with new kit. I’m now generating enough on the solar to fill my batteries, and avoid using the grid. I’ve also exported far more than before. Brilliant experience, well recommended.

Book replacement assessmentSee all services⭐⭐⭐⭐⭐ Absolutely Outstanding Service! My GivEnergy system had completely gone down, and unfortunately I was getting absolutely no support from either the original fitter or the supplier. I was left completely stuck with a system that wasn’t working. I contacted Solar Tech Support and they were absolutely brilliant from start to finish. They quickly got to the bottom of the problem, knew exactly what they were doing, and managed to get my entire system back up and running. Hands down, these guys are absolute experts in their field. The level of knowledge, professionalism and customer service was exceptional, especially when I’d already been left without any support elsewhere. If you have a GivEnergy system and you’re struggling with an issue, don’t hesitate to contact Solar Tech Support. I honestly can’t recommend them highly enough. 5 stars all day long! 🌟🌟🌟🌟🌟
Absolutely fantastic customer service. The team were incredibly helpful, responsive and genuinely willing to do everything they could to help get things sorted. With all the uncertainty surrounding the future of GivEnergy at the moment, it was particularly reassuring to have people who were knowledgeable, approachable and prepared to step in when needed. After a glitch with my firmware update caused problems with my system, these guys really did come in and save the day. They took the time to investigate the issue, explain what was happening and work towards getting everything back up and running. It’s refreshing to deal with a company that genuinely seems to care about its customers and is willing to go the extra mile when something goes wrong. Superb service from start to finish. Many thanks for all the help and support — it’s very much appreciated. Highly recommended.
Outstanding support, very detailed knowledge of the system and clarity on what was needed to fix it, no hesitation in recommending them to all.
Ron responded very promptly regarding my GivEnergy battery issue, his knowledgeable diagnosis was spot on and resolved the issue on first attempt. Would recommend to any and all.
I’ve used Ron a couple of times regarding issues with my Givenergy inverter and batteries after Givenergy went bust. My system stopped working properly so it was a stressful time but Ron resolved the issues and got my system working properly again. He’s really helpful and knowledgeable and I wouldn’t hesitate to recommend him and to use him again if the need arose.
About Eversolar — why your inverter may no longer be repairable
Eversolar was a Chinese solar inverter manufacturer with a UK distribution presence. Their inverters — typically 1–5kW single-phase string units — were installed in volume during the Feed-in Tariff boom of 2010–2013. The Eversolar brand ceased to exist around 2011–2012 when the manufacturer merged and rebranded as Zeversolar, which was subsequently acquired by SMA and itself closed in 2019. Many UK owners have been without manufacturer support for over ten years. Eversolar inverters now aged 12–15 years are experiencing high failure rates, particularly capacitor and power board failures. No spare parts exist and there is no monitoring platform.
The internal collapse of Eversolar as a company left a vacuum with no technical support, no spare parts, and no service pathway for failed units. Unlike some other defunct brands, Eversolar has no third-party specialist service network in the UK — repair is effectively impossible. When an Eversolar inverter fails, the only viable option is replacement with a modern, actively-supported unit. Any investment in repair is not economically rational given the unit's age and the complete absence of support infrastructure.
Why Eversolar inverters fail
The most common Eversolar failure mode. Dead inverter, no lights, no generation. DC bus capacitor failure after 10–15 years of operation. Non-repairable: no spare parts are available.
Eversolar fault codes are undocumented as the manufacturer no longer exists. A fault light with no production usually indicates a protection event caused by aging internal components. Cannot be cleared or diagnosed without replacement.
Still running but producing a fraction of expected output. Capacitor degradation causes MPPT efficiency loss and output clipping. Confirming the loss requires a comparison against calculated roof output.
What should I replace a failed Eversolar inverter with?
When an Eversolar inverter fails, you can replace it with a modern string inverter at similar cost, or upgrade to a hybrid inverter to add battery storage capability. The solar panels and DC cabling remain — only the inverter is replaced. STS assesses your string configuration and recommends the most suitable replacement.
Upgrade to a hybrid inverter with battery storage — most popular choice for Feed-in Tariff-era system upgrades.
