⭐⭐⭐⭐⭐ 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! 🌟🌟🌟🌟🌟
Trannergy Inverter Failed — Assessment & Replacement Options UK
Completely dead, repeated fault trips, or significant output loss — we assess Trannergy failures and recommend the right replacement.
Book replacement assessmentSee all servicesI've spoken to Ron a couple of times with issues with my Givenergy installation. Such a friendly knowledge guy very highly recommended. Thank you very much for resolving my issues
Wow... a firmware update to my inverter sent the whole system into meltdown – the battery discharged, and the house seemed to be drawing power, and the solar, who knows where that was going? Aghhh... A short email exchange with Roland and Solar Tech Support sorted the problem... the firmware had reversed a setting (from when it was installed), and the CT clamp needed to be reversed. As soon as I had done that, the world returned to normal. Thanks, Roland; there is no way I would have come to that conclusion. Would I recommend them? You bet! Worth the fee? You bet, again!
Any long suffering Givenergy customers are strongly recommended to use solar tech support. They fixed my battery issue in couple of hours.
My installer put me through Hell with so botched install that you can not imagine Than Ron came , He did not managed to do miracles (because my system components were impossible to work together) and he Gave me a detailed report of what is wrong , why is wrong , why can not be fixed etc. with all the details which I can use in a claim. Without His his help knowledge and attitude I would've been lost
Givenergy panels and battery had been offline for a couple of months after various changes by Givenergy to their app etc. Ron did a fantastic job of sorting it out - got things up and running almost immediately, followed by some fine tuning to get things fully configured. What a legend - great service, great comms, great result.
About Trannergy — why your inverter may no longer be repairable
Trannergy was a Chinese string inverter manufacturer that supplied single-phase and small three-phase units to UK installers. Models are typically 1–5kW. The brand ceased UK operations before 2016 and no UK distributors carry spare parts. Monitoring portals associated with Trannergy units are no longer accessible. Trannergy inverters remaining in service are aged 10+ years and are at end-of-life for their power electronics.
The lack of manufacturer support means there is no firmware update pathway, no access to technical documentation, and no spare components available. When core components like DC bus capacitors or IGBT modules fail — which is increasingly common for units installed in 2011–2015 — there is no economic or practical repair route. Replacement with a modern, supported inverter is the only viable path.
Why Trannergy inverters fail
Completely dead unit, no lights or display. The most common failure mode for end-of-life Trannergy units. Capacitor failure or power board fault. Non-repairable.
Inverter trips repeatedly and requires manual reset. Indicates failing protection circuits or capacitor degradation causing instability. Likely to worsen progressively.
Inverter appears to run but produces well below expected. Capacitor degradation or IGBT partial failure. Compare against calculated roof output to confirm.
What should I replace a failed Trannergy inverter with?
When a Trannergy inverter fails, you have the option of a like-for-like string inverter replacement, or an upgrade to a hybrid inverter with battery storage. The choice depends on your panel string configuration and whether you want to add battery storage in the future. STS assesses string compatibility and recommends the most suitable modern replacement.
Upgrade to a hybrid inverter with battery storage — most popular choice for Feed-in Tariff-era system upgrades.
