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!

Battery charging & discharging problems
The most common GivEnergy call-outs. Most have a definitive cause that can be identified from monitoring data alone.
🔋 Battery not charging overnight
Charge windows correct but battery stays empty. CT clamp misread, Octopus Intelligent conflict, or incorrect schedule format. Includes the midnight rule and tariff-specific fixes.
Common⬇️ Battery not discharging
Battery shows full but house uses grid. Paused battery, reserve level too high, Export First mode active, or discharge power limit set to zero.
Technical🔌 CAN communication fault
Inverter loses communication with battery over the CAN bus. Firmware mismatch, termination errors, cable faults, or BMS lock state after a protection event.
Alarm🔴 Status light flashing red
Flash patterns indicate different fault states — BMS protection, over-temperature, cell imbalance, or communication loss. Do not open the unit.
Seasonal❄️ Cold weather performance
Battery stops charging below 0°C, capacity drops in cold. Temperature thresholds, winter schedule adjustments, and when it's normal vs a fault to investigate.
⚡ System using grid with full battery
Portal shows grid import despite a charged battery. Normal inverter lag vs sustained configuration issues — and how to tell the difference.
☀️ Battery not charging from solar
Solar generating but battery stays empty. Covers system mode, SoC limits, export limit conflicts, CT clamp errors, Timed Discharge clashes, and temperature lockout.
Firmware📊 SOC bug — battery percentage wrong
SOC dropping, jumping, or stuck at a fixed value. BMS firmware versions 3007–3022, calibration cycles, and fixes for the battery percentage bug across all generations.
Portal, connectivity & configuration faults
Portal issues, settings that keep reverting, and tariff-related lockouts — often caused by third-party API control or WiFi connectivity problems.
📡 Portal offline or not updating
App or givenergy.cloud shows no data. Covers WiFi dongle faults, WiFi dongle hardware failure, cloud-side outages, and firmware updates that broke connectivity.
Common🔀 Settings changing themselves
Charge schedule or system mode keeps reverting without you touching it. Usually an external API — energy provider integration, GivBack, or Octopus Intelligent — overriding your settings.
🔒 Smart tariff lockout
Settings greyed out or reverting because your energy provider controls the inverter via API. How to identify which service has control and remove the lockout safely.
⚙️ Firmware issues
System changed behaviour after an update — schedules broken, monitoring stopped, or new fault codes appeared. What to check and how to recover.
Inverter, solar & hardware faults
Faults with the inverter itself, solar generation, EPS backup power, EV chargers, and error codes that indicate a component issue.
🔌 EPS not working in a power cut
House goes dark in a power cut despite having a battery. EPS may be disabled in settings, the EPS circuit wired incorrectly, or the battery SoC below the EPS threshold.
New🚗 EV charger not working
GivEnergy EV charger offline, showing fault codes, not charging, or charging slowly. Covers fault codes E001–E0026, configuration modes, and network connectivity issues.
🚫 Inverter not turning on
GivEnergy AIO or hybrid inverter with no display, no output, or won't restart. Covers isolator checks, battery deep discharge, firmware failure, and hardware faults.
🌤️ Solar not generating
Zero or unexpectedly low solar output. Covers export limit, DC isolator, grid overvoltage, standby mode, curtailment, and hardware faults — step by step.
🔊 Click of death
Inverter rapidly clicking as it repeatedly tries and fails to connect to the grid. Covers relay failure, AC voltage issues, grid frequency faults, and firmware problems.
🔌 Battery DC MCB tripping
The battery isolator (DC MCB) keeps tripping or won't hold when reset. Covers poor cable termination, buck-boost MOSFET failure, and BMS protection events across Gen 1, Gen 2, Gen 3, and AIO systems.
🔢 GivEnergy fault code index
Full index of GivEnergy error codes — grid faults, BMS alarms, communication errors, over-temperature events — with cause and safe next steps for each code.
How we approach GivEnergy fault diagnosis
Diagnostic methodology
Every fault guide above is based on real GivEnergy diagnostic sessions. We work through each problem using the same approach as a remote session — isolating the cause before recommending any action, rather than swapping parts or factory-resetting without understanding why. GivEnergy inverters log a lot of useful data in the portal: battery SOC history, charge/discharge waveforms, fault registers, and CT clamp readings all point directly to the root cause in most cases. That's why the majority of GivEnergy faults — including most CAN faults, schedule issues, and CT clamp errors — are fully diagnosable without a site visit.
Independent second opinion
If your fault isn't covered by the guides above, or you've worked through a guide and the problem persists, a remote diagnostic session will find the cause. We're independent from GivEnergy and from your installer — so you get an objective second opinion on what's wrong and what actually needs to be done.
GivEnergy problems — common questions
Can't find your fault, or the guide didn't fix it?
A remote diagnostic session identifies the exact cause using your monitoring data, error history, and system configuration — then provides a clear repair plan.
