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

Dennis Brown · May 2026 Trustpilot

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)

Tony Deacon · May 2026 Trustpilot

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.

Mr Machin · May 2026 Trustpilot

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.

Hugh Speirs · Apr 2026 Trustpilot

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.

Christopher · Apr 2026 Trustpilot

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.

Andy Thomas · Apr 2026 Trustpilot

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!

SolaX Faults

Common SolaX problems we diagnose

Every fault below has a proven diagnostic path. Book a diagnostic if you're unsure where to start.

Battery & Charging
🔋
Most common
Battery not charging overnight

SolaX X-Hybrid connected but T-BAT not charging on cheap rate. Most often a ForceTime or TOU schedule configuration error in SolaX Cloud — ForceTime not enabled for the correct period, charge power set too low, or grid charge not active. BST/GMT offsets are very common on SolaX systems.

See diagnostic guide →
⏱️
Tariff
ForceTime / Octopus charging not working

SolaX's ForceTime feature forces the inverter to charge at a set power level during a specified window. It's powerful but frequently misconfigured. Common errors: ForceTime period not overlapping the cheap rate window, SoC target already met, charge power too low to make meaningful progress, or daylight saving time offset causing the window to fire incorrectly.

See diagnostic guide →
📡
BMS
T-BAT / Triple Power BMS communication fault

SolaX T-BAT and Triple Power batteries communicate with the X-Hybrid inverter via CAN bus. A BMS comm fault stops the inverter reading battery state. Causes include a loose CAN cable, incorrect battery type selected in inverter settings, or a firmware mismatch between battery and inverter. Diagnosable remotely via the SolaX Cloud event log.

See diagnostic guide →
🔋
Triple Power
Triple Power battery not recognised

Triple Power HV batteries require the inverter battery type setting to be correctly selected — choosing T-BAT when Triple Power is installed (or vice versa) will cause the inverter to report a BMS fault or show 0% state of charge. Module address assignments and CAN termination must also be correct when stacking multiple Triple Power units.

See diagnostic guide →
⬇️
Common
Battery not discharging as expected

T-BAT battery charged but not powering the house during peak times. Common causes: discharge schedule not configured in SolaX Cloud, minimum SoC threshold too high, or the inverter's self-use mode not active. EPS backup must also be separately configured if backup power during outages is needed.

See diagnostic guide →

About SolaX Power systems — what you need to know

SolaX Power is a Chinese manufacturer producing hybrid and string inverters with a strong UK installed base, particularly from installations between 2015 and 2024. Their core hybrid range is the X-Hybrid series — single-phase X1-Hybrid (3kW–6kW) and three-phase X3-Hybrid (5kW–15kW). These pair with two battery families: the older T-BAT range (T-BAT-SYS-HV, T-BAT-5.8, T-BAT-3.0) and the newer Triple Power high-voltage batteries (5.8kWh per module, stackable to 11.6kWh). Both families use CAN bus communication with the inverter. SolaX's ForceTime feature allows precise charging windows to be configured, but it is frequently set up incorrectly — making it one of the most common causes of overnight charging failure on SolaX systems.

Monitoring is provided by the SolaX Cloud platform. The inverter connects via a Pocket WiFi dongle (2.4GHz only) or Pocket LAN adapter. The most common queries we handle: SolaX battery not charging overnight, SolaX ForceTime not working, SolaX Cloud offline, T-BAT or Triple Power BMS communication fault, and SolaX grid disconnection fault. A common Triple Power-specific issue is the inverter battery type being left on the T-BAT setting after a battery upgrade — this causes the inverter to reject the Triple Power modules. STS provides independent support — not affiliated with SolaX Power.

X1-Hybrid G4 — 3–6kW 1-phase
X3-Hybrid G4 — 5–15kW 3-phase

FAQ

SolaX questions answered

The most common cause on SolaX systems is a misconfigured ForceTime period in SolaX Cloud. The ForceTime window must exactly cover the cheap rate window, charge power must be set high enough to make meaningful progress, and grid charge must be active. BST/GMT offsets frequently cause the window to fire at the wrong time. We reconfigure ForceTime remotely.
Yes — if SolaX Cloud shows offline, the inverter and battery are almost certainly still operating normally. Only the Pocket WiFi dongle has lost its internet connection. The inverter continues to manage solar, battery, and grid independently. We reconnect the Pocket WiFi remotely to restore SolaX Cloud access.
We support all SolaX hybrid generations — X1-Hybrid (G2, G3, G4), X3-Hybrid (G4, G4-Pro), X3-Mega, and the older X-Series range. We cover all SolaX battery systems: T-BAT (T-BAT-SYS-HV, T-BAT-5.8, T-BAT-3.0) and the newer Triple Power range (5.8kWh and 11.6kWh HV modules). A common Triple Power issue is an inverter battery type mismatch — if the inverter is still set to T-BAT after a Triple Power installation, the battery won't be recognised. For string-only SolaX inverters (X1-Boost, X3-Pro), we handle the monitoring and grid fault aspects.
Yes. We configure SolaX Cloud ForceTime periods and TOU schedules to work correctly with Octopus Agile, Go, Intelligent, Flux, or any other tariff. SolaX's ForceTime is powerful but often set up incorrectly — we configure it correctly from scratch in a single remote session.
