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!

GivBat LV range — key specifications (from datasheets)
Two architectures — LV GivBat modules and HV stackable kits
The GivEnergy battery range has two completely different architectures, and getting them right matters for any expansion or diagnostic. The LV side (Gen 1 through Gen 3 GivBat modules) is 51.2V nominal and uses RS485 over the proprietary plug/lug DC+comms cable with master/slave addressing set by dip switches on each battery. The HV side (Gen 3 stackable kits and the AIO 2 expansion battery) is 200–600V and uses CAN bus. There is no "GivHub" — that is not a real GivEnergy product. The Gen 3 hybrid inverters have in-built WiFi/LAN per datasheet; older Gen 1/2 hybrids use the separate WiFi Dongle.
GivBat LV module-by-module specifications
Every spec below is sourced from the official datasheet for that module. Gen 1 small units (2.6, 5.2) are 80% DoD; everything else is 100% DoD. Note: there is no "GivBat 10.2" — that model does not exist in the GivEnergy datasheets. Gen 1 8.2, Gen 2 9.5 and Gen 3 9.5 datasheets explicitly state "Unlimited Cycles / 12 Years"; the Gen 3 5.12 datasheet states "12 Years" with no unlimited-cycles wording.
USB port on Gen 3 batteries is firmware-update only — per the Gen 3 9.5 manual, "The USB of the battery can only be used for firmware upgrades. Please do not plug your phone or other electronic products into the USB of the battery for charging." The Gen 3 manuals also state explicitly that "All Generation 3 battery cables need to be purchased separately" — plug-to-plug, lug-to-plug, and the blanking plug for unused master ports are not bundled with the battery.
HV stackable battery kits — for the Gen 3 8.0 hybrid
The Gen 3 8.0kW hybrid inverter is HV-only — datasheet Battery Voltage Range 120–510V, Communication Interface CAN. It does not accept LV GivBats. Per UKDatasheetStackableBatteriesv2.pdf the HV side ships as pre-built kits with the GIV-BAT-HV-KIT and a count of 3.4kWh battery packs (GIV-BAT-3.4-HV). Comms is CAN bus on the orange HV-kit connector — this is the architecture where the 120-ohm terminator and RJ45 chain language actually applies (unlike the LV side).
Per the stackable batteries manual the minimum stack is 3 packs (10.2-HV) and the maximum is 6 packs (20.4-HV). Commercial systems can parallel multiple stacks. The expansion path here is different from LV — there are no dip switches to set; the kit ships pre-configured.
Temperature, location and BMS behaviour
GivBats are weatherproofed to IP65 (datasheet) but the BMS protects the cells against temperature extremes regardless. Charging is inhibited below 0°C — physically the cells cannot be charged safely at sub-zero, lithium plating is the failure mode. Discharge is permitted down to about -10°C. Per the GivEnergy "Cold Weather Guide for GivEnergy Batteries", expect roughly 10% capacity reduction at 5°C. There is no internal heater.
Inheriting a system in an unheated outbuilding? The "battery will not charge on a frosty morning" complaint is one of STS's most common winter inbounds, and it is not a fault. The BMS is doing the right thing. See our cold-weather page for the full picture.
What the 12-year warranty actually means now
GivEnergy Ltd entered administration on 9 April 2026. The administrator has confirmed no further hardware warranties will be honoured by GivEnergy Ltd. The 12-year warranty figure remains on every datasheet, but the original-manufacturer route to claim it is closed. Alternative recovery routes that may still produce a result:
support@givenergy.co.uk for hardware warrantySee the dedicated GivEnergy warranty page for the full walk-through of each alternative route. STS can prepare an engineer report identifying the fault and confirming it is not caused by installation error — required evidence for any of the routes above.
