GivEnergy · New homeowner guide
Bought a house with a GivEnergy system
Your inverter and battery are fine — the hardware works independent of any cloud or company. GivEnergy Ltd entered administration on 9 April 2026 so the manufacturer warranty route is closed; the cloud is still running but moved to a paid subscription under GivEnergy Software Ltd in May 2026. This guide tells you what you have actually inherited, how to take over monitoring, and what is and is not worth chasing.
Free remote diagnostic · pay only if we fix it — from £75 if remediable remotely
- 150,000+ GivEnergy installs across the UK
- Account transfer, monitoring, settings — all covered
- Independent engineer support, no manufacturer affiliation
After this guide, you will know:
Book a GivEnergy diagnostic 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.
Andy Thomas · Apr 2026
Big thanks to Ron. He was incredibly patient and helpful over the phone, taking the time to walk myself and the installer through every troubleshooting step. Through lots of testing he figured out the issue was definitely a hardware issue, which allows us to consider our next steps. Support fees are clear and they operate a “no fix no fee” policy. It is rare to find that kind of honesty combined with dedicated phone support nowadays. I highly recommend Ron, if you need help with your solar system don’t hesitate to give him a call.

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.
Simon Riddle · Jun 2026 Google
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.

I work for a Solar Company and had a customer with a GivEnergy system that we are not versed in. Ron took the time to explain the issues my customer was having and between us managed to rectify the issues. 10 Stars ... Thanks again STS

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.
→
Hybrid inverter (most common)
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.
→
All-in-One (alternative to a hybrid)
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.
→
GivBat battery modules
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.
→
Monitoring — portal, app, and the local Home option
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.
1
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.
2
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.
3
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.
4
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.
5
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
☐Read the inverter SKU and serial number off the unit
☐Submit portal transfer to GivEnergy Software Ltd via the portal contact form
☐Use the app Home option to confirm generation locally
☐Revoke any unknown third-party integrations in Connected Services
☐Read the warranty page so the post-admin position is clear
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:
→2.4 GHz band only — the WiFi Dongle does not connect over 5 GHz. Your router must have 2.4 GHz enabled.
→WPA2 security — KB explicitly notes WPA3 is not supported. WPA2-PSK or mixed WPA/WPA2 mode is fine.
→RSSI ≥ 60–70% — measured in the dongle's STA interface. KB uses % not dBm; below 60% causes intermittent dropouts.
→Port 7654 open outbound — the dongle's connection to the cloud uses this port. Modern routers and firewalls sometimes block it; that is the single most-missed reason a previously-working system goes offline.
→SSID without special characters or spaces — KB recommends a simple SSID. Renaming the network often fixes "won't connect" issues.
Gen 1 / Gen 2 hybrid — WiFi Dongle
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".
Gen 3 hybrid — built-in WiFi/LAN
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
→
Battery not charging overnight
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.
→
Portal showing offline
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.
→
Red status light on the inverter
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.
→
Battery comms fault
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 backup not working
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.
→
CT clamp the wrong way round
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.
→
Charge settings changing themselves
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:
→
Installer workmanship cover
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.
→
Insurance-backed guarantee (IBG)
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.
→
Section 75 of the Consumer Credit Act 1974
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.
→
MCS Consumer Code
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.
→
Consumer Rights Act 2015
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 running independently
Since May 2026, GivEnergy's remote monitoring runs on a paid subscription tier. If you would rather not depend on it, either for cost or for resilience, the inverter speaks standard local protocols, and third-party tools can read it directly on your own network. These are engineering projects rather than a single download, and entirely optional while the cloud runs.
Home Assistant — local monitoring and automation
The open-source home-automation platform has community integrations that read GivEnergy inverters over the local network, giving live values, history and automation without the cloud. Suited to owners comfortable running a small always-on device such as a Raspberry Pi or NAS.
Predbat — agile-tariff optimisation
A dedicated tool that ties into the inverter locally and runs agile-tariff price-following (Octopus Agile, Flux). For owners who want full agile-tariff intelligence and are happy with a Home Assistant style setup.
Whichever route you take for your own monitoring, STS diagnoses GivEnergy systems over the inverter's local interfaces directly, so a fault can be investigated without any portal access.
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.

Frequently asked questions
The hardware is fine. GivEnergy Ltd was the most-installed UK battery brand before it entered administration on 9 April 2026 — well over 150,000 systems in the field — and the inverter/battery design is solid and widely supported by independent engineers. What has changed is the company behind it: GivEnergy Ltd has ceased trading, and the administrator has been explicit that no further hardware warranties will be honoured by GivEnergy Ltd. Your system continues to generate, charge, discharge and run EPS exactly as before — independent of any GivEnergy company. The cloud and app are run by a separate entity (GivEnergy Software Ltd) which survived administration; from May 2026 the cloud moved to a paid subscription model.
Per the GivEnergy "How to Transfer Ownership" KB document, the items the portal team requested were: (a) proof of property ownership (completion statement, letter from solicitor, or council tax confirmation), (b) the inverter serial number, (c) clear photos of the inverter and any installed batteries. With GivEnergy Ltd in administration, transfer requests now go to GivEnergy Software Ltd via the portal contact form rather than to the GivEnergy Ltd support inbox. Plan for delays. STS can help you assemble the documentation and chase the transfer.
Probably not. Check the inverter display first — if the inverter is showing live generation and battery SoC then the hardware is fine and you are looking at a portal/cloud connectivity issue, not a system fault. The most common cause for a system going offline after a house move is that the dongle is still trying to connect to the previous owner's WiFi. The dongle requires a 2.4GHz SSID with WPA2 security (not WPA3) and outbound port 7654 open to talk to the cloud. The GivEnergy app also has a "Home" option that talks to the inverter over local WiFi without the cloud — useful for confirming the hardware is alive while you sort connectivity.
Legally the manufacturer warranty was always attached to the equipment, not the original purchaser, so on paper it transfers with the property. In practice, with GivEnergy Ltd in administration since 9 April 2026, the warranty is unrecoverable from GivEnergy Ltd itself. Alternative routes that may produce a result depending on how the system was bought: installer workmanship cover, insurance-backed guarantee (IBG), Section 75 of the Consumer Credit Act if any part was paid by credit card, MCS Consumer Code redress for an MCS-certified install, and Consumer Rights Act 2015 against the retailer/installer. See the warranty page for the full walk-through.
No, you can switch supplier freely. GivEnergy systems do pair well with time-of-use tariffs (Octopus Go, Agile, Intelligent, Flux) because the inverter supports timed charge windows directly. If you stay on a smart tariff that uses the GivEnergy API (Intelligent Octopus Go for example), be aware that the cloud is now paid-tier from May 2026 — that may shift the economics. Also audit Account Security → Connected Services in the portal and revoke any third-party token left by the previous owner, otherwise they may still be able to rewrite your charge schedule remotely.
Yes. The inverter, battery, BMS, EPS, CT-clamp loop and any locally-saved charge schedule all run on firmware stored on the hardware itself. You lose remote monitoring and any cloud-side automation, but the system continues to generate, charge, discharge and back up during a power cut. STS diagnoses GivEnergy systems over the inverter’s local interfaces, so a fault can be investigated without portal access. For owners who want their own monitoring back without the paid cloud, third-party tools such as Home Assistant integrations read the inverter locally.
