Bought a house with a GivEnergy system
- 150,000+ GivEnergy installs across the UK
- Account transfer, monitoring, settings — all covered
- Independent engineer support, no manufacturer affiliation
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!

What you have actually inherited
A GivEnergy system is normally three pieces talking to each other. Knowing which generation you have determines what is and is not possible.
DC-coupled inverter that takes the solar strings, the battery and the AC supply into one box. Authentic SKUs per the GivEnergy datasheets are GIV-HY-3.6, GIV-HY-5.0 and GIV-HY-8.0 for the Gen 3 range, with earlier Gen 1 and Gen 2 equivalents at the same nominal power. Gen 3 hybrids are 588 × 214 × 480mm and 32–36kg; max PV voltage is 580V on the 3.6 and 5.0, 600V on the 8.0. All Gen 3 hybrids include in-built WiFi and LAN — no separate dongle needed on these. Gen 1/2 hybrids use the external WiFi Dongle for cloud connectivity.
A single tall enclosure with inverter + 13.5kWh LiFePO₄ battery integrated. Original AC-coupled: SKU GIV-AIO-AC-13.5, 173.7kg, 6kW continuous / 7.2kW peak. AC-coupled 3.6: SKU GIV-AIO-AC-13.5-3.6 (same chassis, 3.6kW on-grid / 6kW continuous off-grid). AIO 2 + MPPT (the flagship): SKU GIV-BAT-13.5-AIO2 with up to 12kW configurable output, six independent PV trackers, 15-year warranty per datasheet. None of these are "Gen 1/2/3" hybrid inverters — the architecture is different.
LV battery modules (51.2V nominal) that hang off a hybrid inverter. Per the datasheets the lineup is: GivBat 2.6 Gen 1 (2.6kWh, 80% DoD), GivBat 5.2 Gen 1 (5.2kWh, 80% DoD), GivBat 8.2 Gen 1 (8.2kWh, 100% DoD, unlimited cycles), GivBat 9.5 Gen 2 / Gen 3 (9.5kWh, 100% DoD, unlimited cycles), GivBat 5.12 Gen 3 (5.12kWh, 100% DoD). There is no "Giv-Bat 10.2" — that model does not exist in any GivEnergy datasheet. Manufacturer warranty was 12 years across the GivBat range, but see warranty section below for the post-administration position.
Access at givenergy.cloud or via the GivEnergy app. Shows live generation, battery SoC, consumption, and grid import/export. The app also has a Home option that talks to the inverter over your local WiFi network — useful for confirming the hardware is alive when the cloud is unreachable. From May 2026 the cloud is run by GivEnergy Software Ltd on a paid subscription model — this is a separate entity from the GivEnergy Ltd that entered administration, and it continues to operate.
Why GivEnergy was popular — and why the hardware is fine
GivEnergy Ltd was the most-installed UK battery brand with over 150,000 systems before it entered administration on 9 April 2026. The hybrid inverter range is well-engineered, the LiFePO₄ battery chemistry is conservative and safe, and the systems integrate cleanly with smart tariffs. The hardware in your house keeps running on locally-stored firmware regardless of GivEnergy Ltd's commercial status — solar charging, battery discharge, EPS backup and CT-clamp logic are all local. What you have lost is the manufacturer warranty route and (from May 2026) free cloud monitoring.
First five steps as the new owner
Work through these in order during your first week. Each takes 15–30 minutes.
Identify your inverter model and serial number
Find the inverter and read the label. Authentic GivEnergy hybrid SKUs are GIV-HY-3.6 / 5.0 / 8.0; AIO SKUs include GIV-AIO-AC-13.5, GIV-AIO-AC-13.5-3.6 and (AIO 2 + MPPT) GIV-BAT-13.5-AIO2. Note the serial — you will need it for the portal transfer.
Can't find it? See How to identify your inverter.
Request the portal transfer (now goes via GivEnergy Software Ltd)
Per the GivEnergy "How to Transfer Ownership" KB the items needed are: proof of property ownership (completion statement, solicitor letter, or council tax confirmation), the inverter serial number, and clear photos of the inverter and any installed batteries. With GivEnergy Ltd in administration, the transfer request is now handled by GivEnergy Software Ltd via the portal contact form (not the old support@givenergy.co.uk address, which is no longer the right route). Plan for delays.
Confirm the system is generating — use the app Home option if portal transfer is pending
While portal access is pending, the GivEnergy app's Home option talks to the inverter over your local WiFi without needing an account — KB-documented in "Connecting Using The Home Option In The App". You can confirm generation, battery SoC and any active faults locally. On a sunny day expect positive PV between 9am and 4pm.
If the inverter shows red LEDs or no generation see System not generating.
Audit Connected Services and revoke any unknown tokens
In the portal, open Account Security → Connected Services. The previous owner may have linked Octopus Intelligent Go, Home Assistant via GivTCP, or other third parties. Each of those holds an API token that can still rewrite your charge schedule — this is the documented cause behind GivEnergy's "Why Are My Charge Settings Changing Themselves?" KB. Revoke anything you don't recognise.
Understand the warranty position post-administration
GivEnergy Ltd entered administration on 9 April 2026 (Gazette notice 5109664). The administrator has been explicit that no further hardware warranties will be honoured by GivEnergy Ltd — so "register the warranty in your name" is no longer a viable step. The recoverable routes are: installer workmanship cover, insurance-backed guarantee (IBG), Section 75 of the Consumer Credit Act, MCS Consumer Code redress, and Consumer Rights Act 2015 claims against the original retailer/installer. See the warranty page for the full walk-through.
Week 1 checklist
WiFi and connectivity — KB requirements
The single most common "offline after moving in" cause is that the dongle is still trying to connect to the previous owner's WiFi — or the new router does not meet the KB-documented requirements. The official requirements per the GivEnergy WiFi configuration guides:
A small USB dongle on the inverter. Reconnect to the new WiFi by joining the dongle's local AP (named something like GE-XXXX), then entering your home WiFi SSID and password. KB guide: "How To Configure Your Internet Router For GivEnergy Systems".
Per the Gen 3 datasheet, the inverter has in-built WiFi and LAN — no external dongle. Reconfigure via the GivEnergy app or use the wired LAN port if your install has one. The "GivHub" referenced in some older guides does not exist as a product.
Offline after moving in?
Nine times out of ten this is connectivity — not a hardware fault. The system continues generating, charging and discharging exactly as before. Start with the KB-documented WiFi checks above; if you are still stuck contact STS and an engineer will configure it for you. Most home WiFi reconnects are 30 minutes' work.
Common issues we see on inherited GivEnergy systems
Usually the previous owner's charge schedule is still active and only fills during their tariff's cheap window — or a Smart Tariff Inverter Lockout is still in place from an Octopus Intelligent integration. Per the KB, only the tariff provider can lift a lockout — do NOT delete the API key first. See Battery not charging overnight.
Check the inverter screen first — if it shows live values, the hardware is fine and this is cloud or WiFi only. Port 7654 blocked by a new router is the most common cause when the WiFi network has not changed. Portal offline guide.
Per the GivEnergy basic-diagnostic KB: green = on and operating, red or off = not operating normally. Note the exact LED pattern and any fault code on the screen. See Status light flashing red.
On LV GivBat batteries (51.2V), inverter-to-battery comms are RS485 over the proprietary plug/lug cable with master/slave addressing set via dip switches — not RJ45/CAN. The most common cause on an inherited system is the addressing was set up for the original stack and a battery has been moved. Battery comms guide.
EPS only powers the designated essential-load circuit and only within the inverter's backup-terminal rating — 3.6kW on Gen 2 5.0 / Gen 3 3.6 / Gen 3 5.0; 8kW with 50A pass-through on the Gen 3 8.0; 6kW continuous on the original AIO; 12kVA off-grid on the AIO 2 + MPPT. Inherited systems often have EPS untested for years. EPS guide.
Export looks like import or vice versa. Per the GivEnergy installer manual, the arrow on the grid CT (ID1) must point away from the consumer unit, in the direction of grid-import current flow. CT clamp guide.
Check the portal Control Logs — API or SERVER entries mean a third-party integration left by the previous owner is rewriting your schedule. Revoke unknown tokens in Account Security → Connected Services. KB: "Why Are My Charge Settings Changing Themselves?".
Warranty position — and what is actually claimable
GivEnergy Ltd entered administration on 9 April 2026. The manufacturer warranty was always attached to the equipment rather than the original owner, so legally it transferred with the house. In practice, with the company in administration and the administrator confirming no further warranties will be honoured, a direct claim against GivEnergy Ltd is not going to succeed. The alternative routes that may still produce a result:
If the original installer is still trading and they offered a workmanship guarantee, that covers installation defects (bad terminations, CT clamp orientation, schedule misconfiguration). Check the installation paperwork that came with the house.
If the installer was MCS-certified, they typically had to provide an IBG. The IBG steps in if the installer ceases trading — which now includes the manufacturer scenario for many homeowners. The IBG certificate should be in the install paperwork.
If any part of the original purchase (deposit or balance) went onto a credit card or a regulated credit agreement, the card provider is jointly and severally liable with the supplier. Section 75 has a low minimum (£100 part of the goods price). Particularly useful when the original installer is also gone.
If the installation was MCS-certified — check mcscertified.com — the MCS Consumer Code gives a redress route via the relevant code body. This is a complaint mechanism rather than a guaranteed payout, but it is the path that keeps escalating where the installer is uncooperative.
Statutory protection against goods that are not of satisfactory quality, fit for purpose, or as described. Claim is against the retailer/installer who sold the system, not the manufacturer. The Act's protections can run for up to six years from purchase (England and Wales).
Check your warranty status — by MCS, not by GivEnergy
Look up the install at mcscertified.com by postcode. The MCS record gives you the install date, the installer's MCS number, and confirms the certification — which is the entry point for IBG, MCS Consumer Code and the strongest Consumer Rights Act position. STS can help you assemble the documentation. See also the full GivEnergy warranty page.
Keeping monitoring (and the system) running independently
If you would rather not depend on the GivEnergy cloud — either because of the paid-tier move or simply for resilience — there are two well-supported alternatives, both of which talk to the inverter locally over modbus:
Free local-first monitoring app from the team behind STS. Installs on your network and reads the inverter over modbus — live values, history, schedules, fault flags. No GivEnergy account required. Same path STS uses for remote diagnostics. See the GivEnergy cloud replacement page.
Dedicated in-home display product that ties into the inverter locally and runs agile-tariff price-following (Octopus Agile, Flux). For owners who want full agile-tariff intelligence without setting up Home Assistant. Predbat sits alongside Sentinel rather than replacing it.
A note on safety and professional advice
This guide is general information, not professional electrical or legal advice. For safety-critical issues (red LEDs, comms faults that will not clear, EPS not working), consult an MCS-accredited engineer. For warranty disputes, the routes above can be assisted by Citizens Advice or a consumer-rights solicitor. Do not open the inverter or battery — there are dangerous DC voltages inside, and the BMS safety functions should not be bypassed.
