Not certain the inverter is faulty? Start with a free remote diagnostic (no fix, no fee) — the cost is credited to the replacement if you proceed with us.
Book replacementDiagnose first — free if we can't fixThe ONLY technical person, who has ever exceeded my own high standards !!!! Being a professional commissioning engineer of over 37yrs in the field of emergency power generation, I approached Ron for some advice on a GivEnergy battery issue as happy to state I don't know everything. Not only did he reply immediately, his advice got the system working and all on a Sunday. You really do not get support as good as this anywhere now for anything. Thank you Ron
Our 3 year old GivEnergy batteries froze. They were showing 0% on the app, but they were fully charged. Some how Ron took over our inverter and remotely cured the problem. We live in King’s Lynn, he is in Leeds I believe. Very grateful.
quick service - sorted in 30 mins. well worth saving yourself hours of reading Facebook forums! thanks
Ron was brilliant. He really tried to help. He spent hours trying to fix our GivEnergy AIO and ultimately it became apparent that it needed parts to fix the BMS management system. As there appears to be no replacement parts available on the market, he gave excellent advice on what options are now available to move forward. He is incredibly helpful and knowledgeable.
Called spoke to Ron. Was very informative and more importantly listen to the issues regarding my system. Was very professional and tackled the problem and had my system back on it's way. Thank you once again Ron
⭐⭐⭐⭐⭐ 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! 🌟🌟🌟🌟🌟
Single-phase, 2–6 kW. Like-for-like or current generation equivalent.
Upgrade to hybrid for battery and EPS compatibility. CT clamp check included.
8 kW+ and three-phase units. Assessed individually.
Commercial three-phase string and central inverters — SMA, Huawei, Solis, SolarEdge, GoodWe. See commercial emergency repair.
All costs confirmed in writing before work starts.
Safe de-energisation in the correct order: battery (if present) off at its own power button first, then AC supply isolated, then DC strings isolated, and the battery DC isolator or MCB opened last. Switching a DC isolator under load damages the contacts and causes arcing, so the power button stops the current first. Where a battery has no separate power button, its module switch is the battery's only control and still comes first. Disconnection and removal of the old inverter. Responsible disposal — we take it away. All connection points documented before disconnection.
Replacement inverter supplied and sourced from authorised distributors. Mounted, earthed, DC strings reconnected with polarity verified. AC connection made including new MCB/RCBO if required. All connections to manufacturer specification.
The system is re-energised in reverse order: AC supply on, DC strings on, battery DC isolator or MCB closed, then the battery on at its power button. Commissioned to UK G99 parameters. Export limit set. Monitoring account created or migrated from old serial number. Battery parameters configured (timed charge windows, SOC, tariff schedule) if applicable. EPS re-enabled if previously active.
G98 or G99 paperwork submitted to your DNO on your behalf. Covers the change of generation equipment. Includes reference number in post-installation report. No extra charge — included in the service.
Full generation test on-site. Battery charge/discharge test if applicable. EPS function test if EPS circuit present. System confirmed operational before engineer leaves site.
Written report documenting: new inverter model and serial number, configuration settings, test results, monitoring portal details, and DNO notification reference. Keeps a permanent record for warranty, insurance, and future reference.
What is not included by default: If upgrading to a hybrid inverter and adding a battery at the same time, the battery hardware and connection are a separate line item quoted alongside the inverter replacement. EPS circuit wiring (if not previously installed) is also quoted separately — see the EPS installation guide. Everything is itemised in the written quote before work begins.
SMA Sunny Boy, Fronius Symo, Solis, SolaX, Huawei SUN2000 (standard), SolarEdge (standard), Growatt ShineWay, Enphase IQ (microinverter), ABB, Kostal. If your brand is not listed, contact us — we cover all UK brands.
GivEnergy AIO, Sunsynk Hybrid, Growatt SPH/SPA, SolaX Hybrid G4, Fox ESS H1/H3, Lux Power LXP, Sigenergy SigenStor, AlphaESS, Huawei SUN2000 + LUNA battery. We recommend options based on your DC array, battery goals, and budget.
Submit details of your system (inverter brand, model, fault description, panel count). If any uncertainty about whether the inverter is truly faulty, we carry out a remote diagnostic first. We confirm the correct replacement specification and provide a written quote covering all costs.
You receive a written quote before any work begins. It covers: replacement unit cost (hardware), installation labour, commissioning, DNO G98/G99 paperwork, and any additional components. Once you approve the quote, we order the hardware and schedule the installation date.
Engineer arrives on the agreed date. Old inverter safely disconnected and removed. New inverter mounted, all connections made to specification. Commissioned to UK G99 parameters. Monitoring portal configured. Battery reconnected and configured if applicable. Full test carried out before sign-off.
Post-installation report provided with all settings, test results, and new inverter details. G98 or G99 paperwork submitted to your DNO — you receive the reference number in the report. You leave with a complete record of the replacement and a system that's fully documented for insurance and future reference.
If your current inverter is a string model (no battery capability), replacing it with a hybrid model opens the door to battery storage in the same job or as a follow-on. This is often the most cost-effective approach — one scaffold hire, one electrical installation, one DNO application.
We can quote the inverter replacement and battery installation together as a package, or separately if you want to phase the investment. Both jobs are assessed and quoted in writing before any commitment.
We carry out inverter replacements on-site across a wide coverage area from our Yorkshire base — including Leeds (our home city), Bradford, Wakefield, Harrogate, York, Sheffield, Huddersfield, Doncaster, Hull, Scarborough, Bridlington, Barnsley, Scunthorpe, Grimsby, Mansfield, Derby, Nottingham, Manchester, Darlington, and Middlesbrough.
Tell us about your system and we'll confirm the right replacement specification, provide a written quote, and schedule an installation date. All costs confirmed before work starts.
Due to unprecedented demand we’re currently only carrying out on-site work in Yorkshire, and replies are taking up to 7 days. Remote diagnostics continue for the whole UK as normal.
