After recently changing my fuse board the ct clamp broke, this meant my inverter was not communicating properly with my GivEnergy system. After several people letting me down, finally got put in touch with Ron. He came out within 24hours & resolved the fault within an hour, no fuse just got on with it. Work was tidy & arrived when he said he would. Ron followed up a few days later to confirm all was still good, great service from all involved.
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)
I’ve used Ron a couple of times regarding issues with my Givenergy inverter and batteries after Givenergy went bust. My system stopped working properly so it was a stressful time but Ron resolved the issues and got my system working properly again. He’s really helpful and knowledgeable and I wouldn’t hesitate to recommend him and to use him again if the need arose.
After 7 months of not being able to access/control my system following a change of wi-fi provider, followed by the news that GivEnergy had ceased trading i was left high and dry. I was unable to get any help whatsoever from my installer, tried various electrical tradespeople etc but no-one knew how to help me. Changed the Dongle but then couldnt get this change recognised in the inverter. Found Solar Tech Support while researching yet again online. Ronald has been amazing. Responding very quickly to my emails and very knowledgeable on the system. Managed to give us the information we needed to get the Dongle up and running and created me another account which now works as it should. His help has been invaluable. Thank you so much. Reviews I saw from other people said Solar Tech Support are very good, but i would say they are Outstanding!! Thanks again for all your help- Mick & Sandra
Ron is one of those rare finds - an engineer's engineer. He insightfully and accurately diagnosed the problems with our GivEnergy system, very quickly, which helped get us back on track. We will be using him again!
Ron was extremely helpful and tried his best to repair/reset our GivEnergy inverter remotely. In the event he was unsuccessful but he couldn’t have been more helpful. If you have problems with a GivEnergy system please contact him. Highly recommended
GivEnergy sold commercial storage in two forms. The Commercial All in One (CAIO) is a single indoor cabinet with the inverter, battery and control gear in one enclosure. The PCS (power conversion system) is a separate three-phase inverter cabinet for larger projects, paired with high-voltage battery cabinets or racks. Both are run by a GivEnergy energy management system (EMS) and the GivEnergy portal. Unless a manual is named, the facts below come from GivEnergy’s own datasheets (October and November 2025).
The range is young. The Commercial All in One opened for pre-order at Solar & Storage Live in October 2024, its installation manual is dated November 2024, and the All in One 2 datasheet is dated October 2025. So there is very little track record, for good or ill.
GivEnergy Commercial Ltd resolved to go into creditors’ voluntary liquidation on 13 August 2026, and a liquidator was appointed the same day. A company in liquidation stops trading. The liquidator’s job is to sell what the company owns and pay its creditors, not to repair equipment or supply parts. The filings are public on the Companies House record for GivEnergy Commercial Ltd.
GivEnergy Ltd, the residential company, has been in administration since 9 April 2026, and its administrator has said no further hardware warranties will be honoured. The app and portal are run by a separate company, GivEnergy Software Ltd, which is still trading. It says its Premium plan covers software only, not warranties or support. So plan as if there is no manufacturer behind the hardware: no warranty repairs, no factory parts route and no manufacturer engineers. The full record for GivEnergy Ltd is on our GivEnergy administration page.
Do not assume, check. A warranty letter, a reseller’s web page or an old support email is not cover if the company behind it is insolvent. We help commercial clients check exactly this as part of an independent audit.
GivEnergy built its commercial support around itself. The PCS manual says every GivEnergy commercial storage system includes an on-site commissioning service: a GivEnergy engineer checks communications with the meter, battery packs, EMS and PCS, runs a low-power test (five minutes charging and five discharging at 10 kW), then a full-power run where the supply allows, and issues the commissioning paperwork that starts the warranty.
The Commercial All in One manual requires commissioning by a trained installer, and EMS installation was limited to installers who had done GivEnergy’s own training. That model needed a manufacturer with engineers to send. With GivEnergy Commercial Ltd in liquidation and GivEnergy Ltd in administration, there is no published route for manufacturer commissioning, expansion or re-commissioning.
The hardware itself is conventional power electronics and LiFePO4 storage. What made it fragile was the support model. An independent O&M arrangement, with your own records of settings, G99 relay configuration and metering, removes that single point of failure. That is what our commercial O&M service is for.
Everything in this section comes from GivEnergy’s own datasheets and installation manuals. None of it is a fault. All of it matters when you judge what the system should be doing.
Neither Commercial All in One datasheet lists a backup or off-grid output, and nor does the 2024 installation manual, although some resellers advertised backup. The PCS datasheet does list an off-grid output and black start, with manual on/off-grid transfer as standard. If your site relies on running through a power cut, have it tested under controlled conditions by a competent engineer, and test again after any firmware change.
The battery works from -10 °C to +55 °C but derates below 0 °C and above 45 °C. The installation manual gives full power only between 10 °C and 45 °C inside the cabinet, and points to a temperature and state-of-charge derating guide. A cold plant room in January and a hot one in July both cost capability when demand peaks.
The Commercial All in One is IP20 and the PCS is IP21: indoor products that need a proper plant space, not a yard wall. The datasheets give 90% depth of discharge, so roughly 62 kWh of each 69 kWh cabinet is usable. Check any payback model was built on the usable figure.
One diagram in the Commercial All in One manual labels the power module 50 kW while the parameter tables describe the 30 kW unit, and the All in One 2 datasheet repeats the original model’s SKU. Metering is specific: one three-phase grid meter plus up to two generation meters, wired by RS485 to the master cabinet only, with shielded cable recommended. Fault-finding built on a misread manual wastes site visits.
Commercial control runs through the EMS, which the manual says must be connected to GivEnergy’s online portal, with an end-user account for the customer and engineer access for the installer. The app and portal are run by GivEnergy Software Ltd, which is still trading. Its free Standard tier works on the local network only: current power flow, battery charge and meter totals. Its Premium plan, a monthly subscription, adds the web portal, remote access, automation, third-party API access and historic graphs. GivEnergy says commercial and large-scale systems may need a different pricing model, so check which plan your site is on. The plans are explained on our portal offline page.
GivEnergy says the hardware keeps working without a subscription. It has not published how the EMS behaves if the portal is unavailable, and in the PCS Remote mode the settings come from the portal. For a commercial asset doing peak shaving on a half-hourly tariff, that matters, so ask an engineer how your site would be checked and changed on site if the portal went down.
We can find almost no public fault reports specific to the Commercial All in One or PCS. The installed base is small and the range is young, so a lack of reports is not proof of reliability. What follows are the recurring reports from GivEnergy’s residential systems that matter most to commercial owners, labelled for what they are.
Owners of residential GivEnergy batteries have reported sudden false state-of-charge drops, including falls of 30 to 48 per cent in around half an hour under light load, with support describing recalibration as not always enough. On a commercial system, peak-shaving decisions are made on that figure, so checking it against metered throughput belongs in the O&M schedule.
Owners have reported problems after updates, from capacity misreporting later traced to failing cells, to a battery discharging when it should have idled. We do not advise self-service firmware updates from the portal or app. On commercial kit, record the firmware versions before anyone changes anything, and talk to us before any update. More in our GivEnergy firmware guide.
One documented installer case describes a battery isolated by a repeatedly tripping DC breaker (traced to poor cable termination) that then sat long enough to fall below its working voltage. Recovery took hours on an external DC supply plus firmware work. The lesson for commercial sites: a tripped breaker is never "leave it until the next visit". A LiFePO4 pack left isolated keeps losing charge, and one that falls too low is expensive to recover.
One owner reported units repeatedly dropping off the local network while staying connected to the cloud, which GivEnergy staff put down to old dongle firmware. Worth knowing because the fix, a restart of the comms module from its own web page, is quick once you know it exists.
If your commercial system is showing a fault right now, the GivEnergy fault-code index and the problems hub cover the diagnostics GivEnergy’s systems share, and the form below reaches an engineer directly.
We are not linked to any GivEnergy company. We do not recommend GivEnergy for new systems, but we support existing ones. With the manufacturer gone, a commercial system needs support that does not depend on it. We start remotely: what the EMS, portal or app shows, your settings and fault history and, where the site allows it, a direct connection with our own remote engineering software. A remote fix is a flat £125, charged only if we fix it.
If an engineer needs to attend, we quote in writing first. Work that needs a part or a commissioning step only the manufacturer could supply is identified in writing before anything is charged, not discovered after.
System down or misbehaving. Same-day remote triage, a flat £125 remote fix charged only if we fix it, and call-outs from £395 in business hours.
Emergency repair →Scheduled inspections, monitoring review, state-of-charge checks, a firmware policy, and documented settings including the G99 relay. Contracts from £10/kWp/annum, minimum from £995/year.
Commercial O&M →Installer gone, or no manufacturer support since the liquidation. We document what is there and check safety and settings. We do not handle GivEnergy account transfers, because the owner can do them in the app. Baseline audit and handover from £995.
System takeover →Paperwork and warranty position, commissioning records, performance against the purchase case, and a written report you can put in front of a board or insurer. Systems up to 50 kW from £745.
Independent audit →Tell us what you have on site (cabinet count, PCS size, what the EMS shows) and why you are getting in touch: a fault, a support gap since the liquidation, or a contract renewal. We reply with a clear next step and written costs before any paid work.
I’ve worked on hundreds of GivEnergy systems and know the kit inside out. If yours is playing up, my promise is simple — no fix, no fee: just £125 if we fix it, free if we don’t.
