This company are a rare gem, I had a very unusual problem following a failed firmware upgrade on my GivEnergy kit. I then found out GivEnergy were in administration and had dismissed all their support staff! None of the usual fixes to try and restore my inverter comms would work, and I looked everywhere, forums, GivEnergy youtube support videos - even AI couldn't figure it out. My installer was talking about huge sums for system replacements, and being vague / evasive about if they'd even install replacement GivEnergy inverter. Enter Solar Tech Support, reassuring and knowledgeable from the very start, I've learnt loads about my solar system though the friendly chat while my engineer worked as he diagnosed the problem and figured out a fix procedure that I've not found anywhere else - amazing. If you need solar system repairs - especially if you like me have been left high and dry by GivEnergy, I cannot recommend this company enough. Give them a call.
Solar River Inverter Failed — Assessment & Replacement Options UK
No lights, no output, or fault codes with no way to diagnose them — we assess Solar River failures and recommend the right replacement.
Book replacement assessmentSee all servicesExcellent service from Solar Tech Support. Extremely quick to respond, easy to deal with and clearly very talented engineers. They were persistent throughout a complex GivEnergy battery issue and resolved everything completely. Highly knowledgeable, professional and reassuring support from start to finish. Highly recommended.
After GivEnergy went into liquidation, just my luck, my battery started playing up (internal board crashed). Contacted my installer - not interested! Found Solar tech support on a Google search. Sooo glad I found this company! Ron is extremely helpful and has plenty of experience. He soon confirmed what the fault was, and helped me to get my system up and running again. Now moved my GivEnergy account to Solar tech support, and will definitely use again if I have more issues. Unusual to find such a helpful company in these times, no morons reading scripts, just direct contact with the engineer.
Excellent response to diagnose a problem on our SolarEdge installation. Kept us informed at every step. Diagnosis quickly completed and solution implemented.
When my GivEnergy system had an issue, I was completely left without support and had honestly lost all hope. Thankfully, I searched online and found Ron, which completely turned things around. After sending him a message, he responded incredibly fast and called me to assure me that he would get the problem fixed. I really admire his dedicated, supportive nature and his determination to find a solution. With this kind of outstanding attitude and customer service, he has absolutely secured a future customer in me.
Ron made more sense in 20 mins than our installer has done over the last 12 months There is a jungle out there and you need someone like Ron to give a comprehensive overview and solution
About Solar River — why your inverter may no longer be repairable
Solar River was a Chinese solar inverter manufacturer that supplied large volumes of single-phase string inverters to UK installers between approximately 2010 and 2015. Models ranged from 1.5kW to 6kW. The company ceased UK operations around 2014–2015. No replacement parts are available through any UK distributor, the monitoring portal is defunct, and the manufacturer no longer provides any technical support.
Solar River inverters that are still generating are typically 10–15 years old — approaching or beyond the design lifespan of power electronics. The most vulnerable components are DC bus capacitors (which degrade with age and heat cycles) and IGBT modules. When they fail, there is no economic repair pathway — replacement with a modern inverter from an active manufacturer is the correct response.
Why Solar River inverters fail
No display, no lights, no output. Most common failure mode for aged Solar River units. Usually caused by DC bus capacitor failure or power board fault. No spare parts are available to repair.
Display flickering, incorrect readings, or display dead with unit still generating. Indicates control board or display module failure. Confirmation that the unit is at end of life.
The inverter continues to run but generates significantly less than expected. Capacitor degradation causes efficiency loss before eventual failure. A generation comparison using roof calculation helps quantify the loss.
What should I replace a failed Solar River inverter with?
When a Solar River inverter fails, you have the choice of a like-for-like string inverter replacement, or an upgrade to a hybrid inverter that adds battery storage capability. The choice depends on your export arrangements, grid connection type, and whether you want to add a battery in the future. A replacement assessment from STS includes a string voltage compatibility check, a recommendation for a suitable modern inverter, and a cost estimate.
Upgrade to a hybrid inverter with battery storage — most popular choice for Feed-in Tariff-era system upgrades.
