Although distance meant it was impractical for me to use them to fully solve the issue, I’m grateful for the help and detail they provided. Don is a real professional gent and a hero in my eyes.
Excellent 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.
When my GivEnergy battery started playing up it became basically useless and several companies I called said they couldn’t help. Solar Tech Support really knew their stuff, communicated very well and resolved the problem quickly. Without them I’d have had to buy a replacement battery.
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.
Big thanks to Ron. He was incredibly patient and helpful over the phone, taking the time to walk myself and the installer through every troubleshooting step. Through lots of testing he figured out the issue was definitely a hardware issue, which allows us to consider our next steps. Support fees are clear and they operate a “no fix no fee” policy. It is rare to find that kind of honesty combined with dedicated phone support nowadays. I highly recommend Ron, if you need help with your solar system don’t hesitate to give him a call.
Our SolarEdge PV system with LG batteries had its first hiccup after 8 years of hard work. The Inverter failed. Fortunately I found Solar-Tech-Support who diagnosed the problem very quickly, ordered a replacement unit and fitted it shortly after we received the unit from SolarEdge. Very thorough and professional approach. Thank you, a solid 5 star recommendation.
Faults on Yorkshire solar systems are accelerating — and most homeowners have nowhere to turn. The region's FiT-era installation boom left tens of thousands of residential systems with no aftercare when their installers folded. Now those systems are 10–15 years old, and the components that wear first — inverters, DC isolators, MC4 connectors, monitoring gateways — are failing at the same time. The panels themselves are fine. Everything around them needs attention.

Major installers gone bust leaving Yorkshire systems unsupported
We diagnose and repair every major solar and battery brand
Manufacturer helplines can run remote diagnostics, but they can't send someone to your roof. Local electricians can do wiring, but they rarely have solar-specific fault experience. That gap — between remote diagnosis and on-site solar repair — is what we fill. We're independent, based in Leeds, and we carry out solar and battery repairs across Yorkshire every day.
These are the fault categories we see most often on Yorkshire systems. Each requires a different diagnostic path — which is why we always diagnose before quoting.
Fault codes, blank screens, red lights, failed start-up, arc fault detection, earth leakage alarms. The most common fault category on 10+ year old Yorkshire systems. Repair or replacement — we confirm which before quoting.
Battery not charging, BMS errors, CAN communication failures, firmware corruption. Common on GivEnergy, Sunsynk, and Growatt systems across the region. Often fixable remotely — hardware replacement only when confirmed.
System underperforming, individual panels not contributing, string imbalance. Caused by panel-level faults, bypass diode failure, shading changes, or degraded connections. We use monitoring data and thermal imaging to locate the fault.
Corroded MC4 connectors, damaged DC isolators, incorrect CT clamp installation, missing earth bonds. Common on systems installed without proper commissioning — especially social housing schemes across South Yorkshire.
Emergency power supply not activating during grid outages, island mode misconfigured, neutral-earth bond missing. We test and verify EPS function on-site so you know it will work when you need it.
Portal offline, WiFi dongle failed, monitoring data gaps. Often the first sign something else is wrong. We restore connectivity, recover historical data where possible, and set up alerts so you're notified of future faults.

When your installer folds, you lose more than aftercare — you lose the engineer who understood your system. Error codes mean nothing without someone who knows your specific inverter model, wiring configuration, and monitoring setup. We diagnose and repair systems left behind by Mark Group, Solarplicity, Snug Energy, and All Seasons Energy every week. No guesswork — we start with a full diagnostic before recommending any parts or work.
