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!

The GivEnergy portal event log lists fault codes with timestamps. Find your code below — each row gives the cause and what to check first. Critical (red) codes may indicate live-DC or BMS protection events — do not open the unit. Warning (amber) codes are protective; Info (green) codes are typically commissioning or transient events. Cloud reference: from May 2026 givenergy.cloud is under GivEnergy Software Ltd on a paid subscription.
GivEnergy portal event-log codes — KB cross-referenced
No AC supply detected at the inverter. Check the AC isolator below the inverter is switched on. Check for tripped breakers at the consumer unit on the solar circuit. Check AC terminal connections are tight.
Same as INV_NO_UTILITY but on an AC-coupled All-in-One or storage variant. AC supply not detected. Check the AC isolator, consumer unit breakers, and the AC terminals at the inverter.
String voltage from solar panels exceeds the inverter limit — 580V on Gen 1, Gen 2 and Gen 3 3.6/5.0 hybrids; 600V on the Gen 3 8.0. Do not touch DC cabling. Requires an engineer to check the panel string configuration — usually too many panels in series for cold-day Voc.
Same as INV_PV_OVER_VOLTAGE on the AIO range. String voltage exceeds the inverter’s Max. PV Voltage. Do not touch DC cabling — engineer required.
Inverter heatsink temperature exceeded its safe operating threshold. Check ventilation clearances per the installation manual. No direct sunlight, not enclosed in a sealed cabinet. Clear dust from heatsink vents. If ambient is in range and vents are clear, an internal fan may have failed.
Inverter has lost communication with the battery BMS. On LV GivBat batteries (51.2V) comms are RS485 over the proprietary plug/lug cable — not RJ45/CAN. Check the battery is switched on, the DC MCB is up, dip-switch addressing is correct (Master = 0,0,0,0; Slave 1 = 1,0,0,0 etc.), and the comms cable is fully seated. On HV stackable batteries the inverter-to-battery interface is CAN — check the orange HV-kit connector. Full comms fault guide →
Persistent battery comms failure — the warning escalated. The battery has stopped responding to inverter requests. Check the comms cable (RS485 on LV GivBats; CAN on the HV stackable kit), full power cycle, and look for a firmware mismatch between battery and inverter. Full comms fault guide →
Battery voltage is critically low. Ensure the battery is switched on (press the side button until the LEDs illuminate) and the first SoC LED is green. Check the DC MCB between inverter and battery is in the ON (up) position.
Battery voltage has dropped below the safe minimum threshold — BMS has entered protection. Commonly caused by deep discharge during EPS operation or a prolonged outage. A slow controlled recovery charge is needed; STS can run this remotely over modbus where the BMS allows. Battery fault guide →
SoC is critically low. Ensure the battery is on. Check the discharge cut-off SoC in Battery Options — if set high the battery may be holding back. Note: per the GivEnergy cold-weather KB, charging is inhibited below 0°C and discharge is allowed to about −1°C, so on a frosty morning the system may sit at low SoC until cells warm.
Battery voltage is low. Ensure the battery is on and the DC MCB is ON. If the battery is on and voltage stays low after a charge attempt, the BMS may be in a protection mode requiring an engineer-led recovery.
Battery cell or BMS temperature has exceeded its safe limit. The BMS will suspend charge and discharge to protect the cells. Per the GivBat datasheets the operating window is 0–50°C charge / ‒10–50°C discharge (Gen 3) or 0–55°C / ‒10–55°C (Gen 1/2). Ensure the battery is not in direct sunlight, no loft installs in summer, ventilation around the unit is adequate. Do not attempt to charge while the fault is active.
Load on the EPS backup circuit exceeded the inverter’s backup-terminal rating. Per datasheets: Gen 2 5.0 backup = 3.6kW; Gen 3 3.6 backup = 3.6kW; Gen 3 5.0 backup = 3.6kW; Gen 3 8.0 backup = 8kW with a 50A pass-through; AIO original = 6kW continuous / 7.2kW peak; AIO 3.6 = 3.6kW on-grid / 6kW continuous / 7.2kW peak off-grid; AIO 2 + MPPT = 12kVA continuous / 14.4kVA peak off-grid. Reduce the load on the backup circuit — strip out electric showers, kettles and ovens. EPS-circuit rewiring is an engineer job. EPS guide →
Grid AC voltage exceeded the upper threshold. Gen 1/2/3 5.0 datasheets list grid range 180–270V; Gen 3 3.6 lists 180–272V. The actual statutory thresholds are set by EREC G98/G99 (commonly 253V and 273V) not by GivEnergy. Check AC isolator and terminal connections; if sound, contact your DNO. Common on sunny days in areas with high solar density. Grid overvoltage guide →
Grid AC voltage dropped below the lower threshold. Check AC isolator and connections. If sound, the supply at your property is outside acceptable limits — contact your DNO.
No PV generation detected during the commissioning check. On hybrid inverters confirm the DC switch is on and the panel strings are present. On AC-coupled AIO systems, generation is monitored via the EM115 (single-phase external meter) or GEM120 (CT-based monitoring) — not a PV-string CT clamp. Confirm the meter is connected and powered.
Per the GivEnergy KB ("Understanding and Removing a Smart Tariff Inverter Lockout"), an active energy-tariff agreement (e.g. Octopus Intelligent) has locked inverter controls. Symptom: settings refuse to save, schedules will not update. Only the energy provider can lift the lockout — do NOT delete the API key first, that orphans the lockout. Contact the tariff provider to be removed from the integration cleanly.
Communication with the external meter has failed. The meter is likely an EM115 (single-phase, mounted close to the inverter) or GEM120CT (CT-based monitoring bundle). Check the meter comms cable is in the correct socket on the underside of the inverter and that polarity (power and comms) is correct.
The portal has not received data from the dongle recently. Check the dongle LED — solid means WiFi up. KB-documented WiFi requirements: 2.4 GHz only, WPA2 (not WPA3), RSSI ≥ 60–70% in the dongle STA interface, port 7654 open outbound. Port 7654 being blocked by a router/firewall change is the single most common cause. Portal offline guide →
Meters have not been enabled in the commissioning portal. Go to My Inverter → Remote Control → Enable Meters and enable the number of meters installed. Installer commissioning step rather than an end-user action.
The grid CT clamp (ID1) is the wrong way round. Per the GivEnergy installer manual and portal commissioning docs, the directional arrow on the CT body must point away from the consumer unit, in the direction of grid-import current flow. A reversed CT inverts import/export readings. CT clamp guide →
Battery is not charging from excess solar. Restart inverter and battery in the correct sequence. Check system mode, CT direction, and SoC limits. Battery not charging guide →
Battery is not discharging to meet house demand. Restart inverter and battery. Check system mode, discharge cut-off SoC, and that the CT clamp is reading the correct circuit (grid, not generation).
