Brilliant support to get my solar battery working again. I didn’t expect help on a Saturday but Ron answered the phone, listened and sent me the information I needed to get it going, answered questions etc. A brilliant service I’d happily recommend.
The grid was over-voltage and the proof was already in his inverter
- Real customer fault
- Proven from the inverter’s own data
- Evidence pack for the DNO
If your system keeps dropping out with an over-voltage fault, the supply is probably out of tolerance — and your inverter has likely been logging the proof. We can pull it and build the case for the network operator.
Ask about an over-voltage checkFoxESS support hubRon 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 back within a day and gave good advice.
Ron was extremely helpful and tried his best to repair/reset our GivEnergy inverter remotely. In the event he was unsuccessful but he couldn’t have been more helpful. If you have problems with a GivEnergy system please contact him. Highly recommended
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.
A superb service from Ron who went beyond the normal service received from other Tech support companies. I live abroad and was badly let down when my givenergy system failed (and the company went bankrupt) and the local supplier ran away from the problem. Ron sorted the problem and even accessed specialist coding for the inverter that would not be available for suppliers. Ron also ran a full diagnostic to insure that all was in good working order afterwards. Without Rons support and patient assistance I doubt I would ever have got the system back up and running. Well done and thankyou and you have a customer for the future.
Thank you for your diligence. On this occasion the battery was able to be saved but they have given a route to hopefully arrange a repair from the manufacturer.
Ronald was great to help me sort out my giv energy inverter issue since company has gone bankrupt in april 26.
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.
Very very helpfuland so quick. Made sure that a non expert like myself understood what the problem was and how to resolve it.
Contacted Solar Tech about my Givenergy battery storage system that wasn't working. Battery status was "idle". Given the company Givenergy had gone bust, I need independent quality technical help. Very patient and clearly very knowledgeable about battery systems Ron diagnosed possible issues and suggested several possible remedies. Worked our way through them and fortunately it began to work. The fault was very specific and only an experienced engineer would have thought to check. Suffice to say I'll be back if I need independent support again. Lastly you only pay if there is a solution. Outstanding.
My Givenergy battery stopped working nearly a month ago. After unsuccessfully reaching out to my installer, who looks like he's also busted, I found Solar Tech Support on a Google search. They fixed my issue in a couple of hours. Any frustrated Givenergy customers, I highly recommend these guys.
Excellent response to diagnose a problem on our SolarEdge installation. Kept us informed at every step. Diagnosis quickly completed and solution implemented.
Prompt and useful support regarding my Sunsynk system lack of performance. Ronald simplified the technical issues to make them understandable. Many thanks, looking forward to follow up.
Amazing support, went out of his way to help try and get us back up and running
What a fantastic service. Had my fault diagnosed within minutes and actually managed to resolve the issue remotely within a few minutes more. This guy is like a “Solar Batman” helping consumers fix their problems using his extensive industry knowledge and expertise. Outstanding service. Thank you so much.
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.
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.
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
I have a GivEnergy system consisting of two batteries, two inverters and a controlling EMS (Energy Management System) which has not worked since Nov 2025. After six months I discovered Solar Tech Support, reached out to them and Ron phoned me back – how often do you get that service? Could not be more helpful – worked directly with me over the phone, outside what I would call normal working hours. Lucid explanations and we were able to discuss the issues and history using camera and email history. As this was a very rare setup, Ron was able to access an EMS expert in the field to confirm the solution. One sunny day in, I am now only paying for standing charge and a few pence for spikes in grid consumption while battery catches up with house demand.
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 want out of is way to help, nothing was to much. He was very thorough in what he did Very knowledgeable I would highly recommend Ron and his company He did a fantastic job for me. if you have any problems, he'll do his best to help you out and resolve your problem. I wouldn't hesitate to recommend them
Ron took me through a diagnostic to confirm my GivEnergy Inverter had a fault. A common one as it turns out with the AC Inverter. As GivEnergy is defunct there is no immediate fix, aside from sourcing 2nd hand replacement. It may be that a fix becomes available over the summer which would make a lot of GivEnergy customers happy (Again)
Contacted Ron with a problem and he sorted it out quickly with no problems at all. Very knowledgeable on anything solar/ batteries. I would recommend him to anyone
I'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
Contacted Solar Tech Support in desperation. After explaining the issues I had with my system a diagnosis was made and a solution proposed. Fantastic service, even contacted a manufacturer to arrange replacement parts for me. Great communications, explained all they were doing and what I had to do, clearly and precisly. Followed up to confirm all was ok. Excellent service.
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.
Contacted Solar Tech Support when trying to understand what my Givenergy inverter problem might be and what might be my options. Received good/honest advise which backed up my thoughts.
Ron is a super star. Two months ago my GivEnergy battery failed a firmware upgrade leaving it a brick. My installer couldn't/wouldn't fix it. GivEnergy couldn't/wouldn't fix it. Then they went into administration and all hope was lost. A flurry of emails later and Ron had diagnosed the fault (failed USB flash drive, something I'd suspected) and talked me through resolving it. Two months of nothing resolved in about 3 hours. It's great to work with someone who pays attention to the details, knows that they're doing (not just following a script) and gets stuff sorted without a fuss or up-charging.
I can add to the list of customers who had already 'given up' on GivEnergy due to their appalling customer service, and that was before they went into administration. So you can imagine my desperation when, having changed my ISP and my Inverter, predictably, proving to be the only device that didn't connect automatically to my new network, I found zero prospect of any customer support with GivEnergy having called in the administrators just five days earlier! The salvation came from Solar Tech Support. My IT advisor stumbled across their web site and some very helpful tips for beleaguered GivEnergy customers, as well as an offer to provide direct assistance. Nothing ventured, I decided to drop them an E-Mail, with very low expectations based on my experience of GivEnergy customer support. Within an hour Ron had responded with some pin point advice, and after a few exchanges of E-Mails he had nailed the problem, enabling the combined efforts of my IT advisor and solar installer to resolve it and reconnect my Inverter. Thank you Solar Tech Support, and Ron in particular, for coming to the aid of a deserted and despondent GivEnergy customer. Expert, razor sharp advice and first class customer service, even though I wasn't officially a customer.
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.
I sent a message on their website regarding a problem I have on my Givenergy system. Although not supplied by Ronald, I thought it was worth an email. Within the hour on a Saturday, he phoned and we discussed the problem. He logged in remotely and gave excellent advice. I'm too far away for his on-site help but he did diagnose the problem and was happy also to chat through my thoughts about an upcoming solar/battery install I'm planning. Great bloke.... if only he was nearer!

Kerry got in touch because his solar inverter kept shutting itself down — several times a day, every day. He was already fairly sure the cause was high mains voltage. What worried him was the next bit: how do you actually prove that to a network operator, and get them to do something about it? As it turned out, the proof had been sitting inside his own inverter the whole time.
The problem — a system that kept dropping out
Kerry's FoxESS hybrid kept throwing the same fault — "Code 28 — 10 Minute Average Grid Voltage Fault" — and disconnecting from the grid. To him it looked like the system kept breaking. In fact it was protecting itself. He suspected the grid voltage was simply too high — a common problem as more solar goes onto a network, and especially for homes near the end of a long supply cable — but he had no voltage logger, no obvious way to evidence it, and a very reasonable fear that a phone call saying "I think my voltage is high" would go precisely nowhere.
Why “the grid is too high” is hard to prove on your own
A network operator is not going to re-tap a transformer or reinforce a street on a hunch. They want evidence: the voltage, measured, over time, breaching the limit. Most homeowners don't own a power-quality logger — and by the time anyone comes out to check, the voltage may happen to look fine. That catch-22 is exactly why people give up.
But there is a piece most people miss. A modern grid-connected inverter is continuously measuring the grid voltage at its own terminals, and logging it. The evidence isn't something you need to go and capture — it has already been recorded, for months, by the very device that keeps tripping.
What the inverter’s own data showed
We exported the inverter's grid-voltage history and its fault log from the FoxESS cloud and analysed them. Across a 19-day window the supply voltage:
- peaked at 255.9 V — nearly 3 V over the 253 V statutory limit;
- exceeded 253 V on every single day of the period;
- sat at or above 250 V for roughly half the time — chronically pressed against the ceiling.

And here is the part that settles the argument. A large share of the breaches happened overnight — between roughly 2 am and 5 am — when Kerry's solar was generating nothing at all. That single fact dismantles the usual deflection that "it's your own solar pushing the voltage up." At three in the morning there is no solar export, so a reading above 253 V can only be the network's own voltage. During the day, his solar then stacks on top of an already-high base and pushes it further over the limit.
Eighty-nine shutdowns in a fortnight
The inverter's fault log recorded 89 over-voltage disconnections in 15 days — about six a day, and as many as fourteen on the worst day.

Every one of those is the inverter doing exactly what the grid-connection rules (Engineering Recommendations G98 / G99) require: disconnecting when the 10-minute average voltage exceeds 253 V. The inverter wasn't faulty — it was the canary, faithfully logging a supply that was out of tolerance.
What the supply is legally allowed to be
The voltage a domestic supply must be kept within is set by the Electricity Safety, Quality and Continuity Regulations 2002. A 230 V supply is permitted to vary by +10% / −6% — a band of 216.2 V to 253 V — and the network operator carries a legal duty to keep it there. A supply repeatedly reaching 255.9 V is outside that band, full stop. Once a customer reports it, the DNO must respond within five working days, or offer to investigate within seven, under the Guaranteed Standards of Performance — with a penalty payment due to the customer if it does not.
Turning the data into something the DNO can’t wave away
We pulled all of it together into a formal report on letterhead: the voltage logs, the fault log, a day-by-day breakdown, the relevant regulations, and a plain explanation of why the inverter is behaving correctly while the supply is not. Crucially, every figure is sourced from the inverter's own records — not opinion. That is the difference between "I think my voltage is high" and a documented breach the network operator has a statutory duty to act on.
The point, for Kerry, is that he didn't need to buy equipment or win a technical argument. The evidence already existed. It simply needed extracting, analysing against the right limit, and presenting in a form the DNO cannot reasonably dismiss.
If your inverter keeps tripping on over-voltage
You're probably not imagining it, and you're almost certainly not at fault. A grid-tied inverter that repeatedly drops out on over-voltage is usually telling you the truth about your supply — and the proof is likely already sitting in your monitoring. We can pull it, analyse it against the statutory limit, and build the evidence pack that gets the network operator to take action.
