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
A really big thank you to Ron and his team, he has vast amounts of knowledge and got my system back up and running, also good to get on with. I was absolutely lost as to know what to do, no help from installer and somehow came across Ron and am I glad I did. I would definitely definitely recommend him to anyone who has faults with there solar system, any make I would say. Thanks again Ron a pleasure meeting you.
Absolutely wonderful support. I have a GivEnergy system that was installed in 2022, and a firmware update was flagged in the app, so I proceeded to update the software .... and immediately regretted it, as my inverter came up with an error, and was not working at all! With no GivEnergy support available, and my installer saying there was nothing he could do, I googled help, and found Ron. What a stroke of good luck! Submitted an on line enquiry late morning, and received phone call just after 5 pm, and later that evening Ron was able to supply me with old firmware no longer available on the GivEnergy web site. I was then able to update the firmware using a GivEnergy youtube video as reference, and hey presto the system was back up and running. One further slight adjustment by Ron and we are back normal. What a relief. I have no hesitation in recommending Solar Tech Support if you have a problem. Great service! And if you are a GivEnergy system owner, whatever you do, DO NOT UPDATE FIRMWARE!
Solar Tech Support is an absolute lifesaver. My solar and battery system stopped working completely, but after one quick phone call, they fixed the problem straight away. The original provider, GivEnergy, has gone into administration, leaving me entirely without support from the original installers. It was a terrible situation on GivEnergy’s part, but thankfully, Solar Tech Support came to the rescue!
My 90-year-old father-in-law had a solar system installed nearly three years ago that never worked properly and kept tripping out. Neither the original installer nor GivEnergy could resolve the issues, and we were even pushed towards replacing the system entirely when GivEnergy went bust. I contacted Ron at Solar Tech Support via WhatsApp, and within a few hours he had diagnosed multiple faults — including incorrect wiring that posed a potential fire risk. He carried out a home visit in Nottingham for £295 (including parts), fixed everything, completed firmware updates, and ensured the system was fully operational. Since then, it has worked perfectly. Ron was knowledgeable, responsive, and took the time to explain everything clearly. Highly recommended — excellent value and complete peace of mind.
My GivEnergy hybrid inverter + battery system had worked faultlessly for 3 years when it suddenly stopped charging and discharging the battery. On contacting my supplier, who had used a sub-contractor for the installation work, I was provided with an email address at GivEnergy but, as it turned out, this is only for GivEnergy Software who are not able to assist. A Google search led to the Solar Tech Support web site, which contains a wealth of helpful information. I requested a remote solar diagnostic, and after providing Ron access to my inverter, he was able to identify and fix the problem within minutes. I am very impressed by Ron’s expertise and knowledge, which included useful information on the current state of GivEnergy Ltd. I would thoroughly recommend Solar Tech Support.
GivEnergy sells commercial storage in two forms. The Commercial All in One (CAIO) is a single indoor cabinet aimed at SMEs: inverter, battery and protection in one enclosure. The PCS (power conversion system) is a standalone three-phase inverter cabinet for larger projects, paired with separate high-voltage battery racks. Both are controlled through a GivEnergy energy management system (the EMS-C on CAIO systems, an EMS within the battery racking on PCS systems) and the GivEnergy portal.
The range is young. The CAIO opened for pre-order at Solar & Storage Live in October 2024, its installation manual is dated November 2024, and the 50 kW V2 followed in late 2025. That matters when you look for track record: there is very little of it yet, for good or ill.
The largest problem with GivEnergy commercial hardware in 2026 is the company behind it. GivEnergy Ltd entered administration on 9 April 2026, ceased trading, and made its staff redundant. The administrator has confirmed that GivEnergy Ltd will not honour further hardware warranties or user support.
The commercial position is more nuanced, and the nuance matters. GivEnergy Commercial Ltd and GivEnergy Software Ltd were not placed in administration and continue trading. On paper, commercial support continues. In practice, the residential entity's workforce is gone, no published route exists for commissioning or expanding commercial systems on the pre-administration terms, and it is unclear how much shared engineering and field resource remains behind the commercial operation. The full corporate record, including what residential owners should do, lives on our GivEnergy administration page.
Do not assume, verify. Any statement about current warranty or support for the commercial line should be checked against which GivEnergy entity issued it, in writing. We help commercial clients do exactly this as part of an independent audit.
GivEnergy designed its commercial support model around itself. The PCS manual states that all GivEnergy commercial storage solutions include an on-site commissioning service: a GivEnergy engineer verifies 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 clock.
The same pattern runs through the whole range. The CAIO manual requires commissioning by a trained installer, EMS-C installation was restricted to installers who completed GivEnergy's own training, and distributors listed a paid enhanced commissioning service under which GivEnergy staff physically connected batteries, racks, metering and EMS. That model works while the manufacturer has engineers to send. With the residential entity's workforce gone, how much engineering resource remains behind the commercial operation is unclear, and there is currently no published route for commissioning, expanding or re-commissioning commercial systems on the pre-administration terms.
The hardware itself is conventional power electronics and LiFePO4 storage. The operating model concentrates risk in one manufacturer's staffing. An independent O&M arrangement, with your own documentation of settings, G99 relay configuration and metering, removes the single point of failure. That is precisely what our commercial O&M service exists to do.
Everything in this section comes from GivEnergy's own datasheets and installation manuals. None of it is a fault. All of it has been the root of a commercial disappointment somewhere, usually because a spec sheet headline was read without the footnote.
Neither the CAIO 2 datasheet nor the CAIO installation manual describes an EPS or backup output, although some resellers market the system with backup claims. The PCS manual does describe off-grid operation for PCS and rack systems. If backup load support matters to your site, require written confirmation for your exact configuration, and an on-site test, before treating it as real.
The CAIO delivers full power only between 10 °C and 45 °C internal temperature, with reduced power outside that band, and the manual points to a temperature and state-of-charge derating guide, so output also derates by SOC. The battery derates below 0 °C and above 45 °C. A cold plant room in January and a hot one in July both cost you capability at exactly the moments demand peaks.
The CAIO is IP20: an indoor product needing a proper plant space, not a yard wall. Separately, on GivEnergy's shared three-phase platform, output balances equally across phases by default. One documented residential case showed an 11 kW unit delivering roughly a third of nameplate to a single-phase load until support enabled the unbalance setting. On a commercial site with lopsided single-phase loads, have phase unbalance behaviour confirmed and configured deliberately.
The CAIO manual contains an internal inconsistency: one diagram labels the power module 50 kW while the parameter tables describe the 30 kW unit. Metering is specific too: one three-phase grid meter plus up to two generation meters, wired by RS485 to the master cabinet only, with shielded cable recommended. Quoting, O&M documentation or fault-finding built on a misread manual wastes site visits.
Commercial control runs through the EMS-C, which per the manual must be connected to GivEnergy's online portal, with an end-user account for the customer and engineer access for the installer. That portal is run by GivEnergy Software Ltd, which moved remote access to a paid tier from May 2026: remote app and web access, historic data, automation and API integrations sit behind a £4.99 per month subscription for standard systems, with the free tier limited to local-network access. GivEnergy states commercial and large-scale systems may need a different pricing model, so confirm the commercial rate in writing.
Cloud dependency also means cloud outages. In one incident owners linked to the AWS outage of 20 to 21 October 2025, the portal and both apps failed for many users, with reports of control commands not executing and some owners describing unexpected system behaviour during the outage. For a house battery that is an annoyance. For a commercial asset doing peak shaving on a half-hourly tariff, hours of lost control have a price, so do not assume graceful degradation: at minimum you lose visibility and the ability to change behaviour while the cloud is down.
Honesty first: we can find essentially no public fault threads specific to the Commercial All in One or PCS. The installed base is small and the range is young, so absence of reports is absence of evidence, not proof of reliability. What follows are the recurring reports from GivEnergy's shared platform and residential fleet that are most relevant to commercial owners, labelled for what they are.
Owners of residential GivEnergy batteries have reported sudden false SOC drops, including falls of 30 to 48 per cent in around half an hour under light load, with support describing recalibration as not always sufficient. On a commercial system, SOC integrity is what peak-shaving decisions are made on, so periodic verification against metered throughput belongs in the O&M schedule.
Owners have reported misbehaviour after updates, from capacity misreporting later traced to failing cells, to a battery discharging when it should have idled. Our general guidance on GivEnergy firmware issues applies doubly on commercial kit: schedule updates, never let them land silently mid-billing-period, and record versions before and after.
In one community thread from late 2025, several users described whole-home backup systems going dead during power cuts despite full batteries. That is the residential analogue, and the commercial cabinet does not even document backup. If any part of your business case assumes islanding, test it under controlled conditions and repeat the test after firmware changes.
One documented installer case describes a battery isolated by a repeatedly tripping DC breaker (traced to poor cable termination) that then sat dead long enough to fall below operational voltage, needing hours on an external DC supply plus firmware work to recover. The commercial lesson: a tripped breaker is never "leave it until the next visit". LiFePO4 packs self-discharge into a hole that gets expensive to climb out of.
One owner reported units repeatedly becoming unreachable on the local network while staying cloud-connected, attributed by GivEnergy staff to outdated dongle firmware. Worth knowing because the fix (a comms module restart via its built-in 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 shared-platform diagnostics, and the form below reaches an engineer directly.
We are independent of every GivEnergy group company. For commercial owners that independence is now the point: your system needs a support arrangement that does not depend on one manufacturer's staffing. We are straight about limits, too. Work that genuinely requires manufacturer-proprietary commissioning or parts gets identified in writing before anything is charged, not discovered after.
Scheduled inspections, monitoring review, SOC verification, firmware policy, and documented settings including G99 relay configuration. Contracts from £10/kWp/annum, minimum from £995/year.
Commercial O&M →System down or misbehaving. Same-day remote triage, no-fix-no-fee on the remote diagnostic, call-outs from £295 in business hours.
Emergency repair →Installer gone, or manufacturer support gap since the administration. We document what exists, verify safety and settings, and take on ongoing responsibility.
System takeover →Warranty-entity check, commissioning paperwork review, performance verification against the purchase case, and a written report you can put in front of a board or insurer.
Independent audit →Tell us what you have on site (cabinet count, PCS size, what the EMS shows) and what prompted the enquiry: a fault, a support gap since the administration, or a contract renewal. We respond 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 £75 if we fix it, free if we don’t.
