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 (their Trustpilot reviews don't lie!). 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!

Common Sofar Solar problems we diagnose
Sofar Solar has a large UK install base across two distinct product generations — HYD hybrid inverters and the older ME3000SP AC-coupled units. We support both.
Sofar HYD hybrid inverters use SolarMan for schedule configuration. If the battery isn't charging on cheap rate, the TOU schedule likely has the charge window disabled, grid charge toggled off, or the SoC minimum already met. For ME3000SP units, the schedule is set locally on the device — a common source of confusion after router changes.
See diagnostic guide →The Sofar ME3000SP is an AC-coupled BESS managing battery charge/discharge alongside an existing solar system. Common issues: schedule set incorrectly after a power cycle, EPS mode not triggering during a grid outage, battery not communicating correctly over RS485, or the unit being stuck in a fault state requiring a configuration reset.
See diagnostic guide →Sofar HYD hybrids communicate with their paired battery via CAN bus or RS485. A BMS comm fault stops the inverter from reading battery state, preventing charging and discharging. Common causes: wrong battery type selected on the inverter, loose CAN cable, or Pylontech/Dyness protocol mismatch if a third-party battery is paired.
See diagnostic guide →Battery fully charged but the Sofar inverter isn't drawing from it. Check the discharge schedule and minimum SoC threshold in SolarMan. A BMS protection trip will also prevent discharge — check the inverter event log for battery protection errors.
See diagnostic guide →Sofar inverter powered but not generating. Check SolarMan for DC input voltage — if zero or very low, inspect DC isolators and PV string connections. DC isolation faults (G-ISO) and MPPT errors can suppress production while battery functions continue normally.
See diagnostic guide →Sofar inverters comply with G98/G99 and disconnect if grid voltage or frequency exceeds limits. The inverter reconnects automatically. In high-solar-density areas, repeated trips may require export limit configuration. The ME3000SP can also issue grid fault codes related to its AC coupling point.
See diagnostic guide →Sofar HYD hybrids support EPS mode, but it requires dedicated EPS wiring and must be enabled in settings. The ME3000SP also supports an EPS/off-grid mode but is frequently not commissioned for it. If backup power failed during an outage, EPS was likely never set up — or the load exceeded the EPS output rating.

About Sofar Solar systems — what you need to know
Sofar Solar is a Chinese manufacturer with a large UK installed base across two distinct product generations. The ME3000SP was one of the most widely installed AC-coupled battery energy storage systems in the UK between 2016 and 2021 — it retro-fits to existing solar systems to add battery storage and operates independently of the solar inverter. The newer HYD series (HYD 3600–6000 EP) are all-in-one hybrid inverters combining solar MPPT, battery management, and grid connection. Both use SolarMan for monitoring — the same platform used by Sunsynk and Hanchu systems.
The ME3000SP has a large installed base of older units now approaching the 7–10 year mark, and configuration faults or component wear are increasingly common on these systems. For newer HYD hybrid systems, the configuration issues are similar to other SolarMan-based hybrids. Common queries: Sofar ME3000SP not charging, Sofar HYD battery not charging overnight, Sofar SolarMan offline, ME3000SP EPS mode fault, and Sofar battery BMS comm fault. STS provides independent support — not affiliated with Sofar Solar.
STS supports all major inverter and battery brands. Sofar HYD inverters are often paired with Pylontech or Dyness batteries — visit those brand pages for battery-specific guidance.
