Following the storm my givenergy system was effectively useless. I contacted STS after seeing other reviews and recommendations and they delivered. My system was a challenging one, but is now back working as it was - this was all done remotely by them using their own software and expertise. Great service, thank you!
STS were incredibly responsive and helpful In diagnosing an issue with my GivEnergy inverter. Although distance meant it was impractical for me to use them to fully solve the issue, I’m grateful for the help and detail they provided. Don is a real professional gent and a hero in my eyes.
I had a red status light on my GivEnergy battery pack and Ron at Solar Tech Support was a great help resolving the problem. He was able to do a remote diagnosis of the invertor BMS firmware and hardware and gave very quick practical and professional support. Thanks Rob

Particularly useful in helping to fix my GivEnergy All in One system with a disabling fault.
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.
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 include 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 3.6 and 5.0kW. The 3.6 and 5.0 run LV GivBat batteries; the Gen 3 8.0 and 10.0kW models run HV stackable batteries. A three-phase home may have one of GivEnergy's three-phase HV hybrids, from 6 to 20kW. 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 from commissioning per its manual. 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. The LV lineup is: GivBat 2.6 Gen 1 (2.6kWh, 80% DoD), GivBat 5.2 Gen 1 (5.2kWh, 80% DoD), GivBat 8.2 (8.2kWh: the version sold from about 2019 to 2021 is 80% DoD, about 6.6kWh usable; the version sold from 2021 is 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). On an LV system, more batteries add storage, not power: the battery side tops out at about 3.6kW whatever the stack size (2.6kW on a Gen 1 hybrid). The Gen 3 8.0 and 10.0kW hybrids use HV stackable batteries instead, such as the three-module 10.2kWh GIV-BAT-10.2-HV kit, and can deliver more power. Warranty depends on the install date: batteries installed from 11 September 2023 carried 12 years; batteries installed before that carried 10 years at 70% capacity. See the warranty section below for the position since the administration. If the stack the previous owner left you is smaller than you would like, adding capacity is straightforward — we supply and install extra GivEnergy batteries at one fixed price per unit.
The GivEnergy app and the web portal at givenergy.cloud show live generation, battery SoC, consumption, and grid import/export. Both are run by GivEnergy Software Ltd, which is still trading. It is a separate company from the GivEnergy Ltd that entered administration. Since May 2026 the app's free Standard tier works on your home network only: live power flow, battery charge and meter totals, and, since app version 4.0.5 (26 May 2026), full local control of the inverter with no login. GivEnergy Premium (£4.99 a month) adds the web portal, remote access, automation, third-party API access and historic graphs. The app's Home option talks to the inverter over your local WiFi network, which is useful for confirming the hardware is alive when the cloud is unreachable.
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 remote monitoring: the free app now works on your home network only.
Work through these in order during your first week. Most take 15–30 minutes.
Find the inverter and read the label. Authentic GivEnergy hybrid SKUs include GIV-HY-3.6 / 5.0 / 8.0 (there is also a Gen 3 10.0kW and a three-phase range); 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 as well. The app transfer does not need it, but GivEnergy Software asks for it, or the account username, with the installation postcode, if you have to email them about the account.
Can't find it? See How to identify your inverter.
GivEnergy transfers are now done between customers in the app. The current owner updates the GivEnergy app, logs in, taps the account button at the top right of the home page, chooses Transfer Hardware and enters the new owner's email address. The new owner accepts from the email they receive. Read the transfer guide.
If you have moved into a home with a GivEnergy system, ask the previous owner or the estate agent to do this for you. GivEnergy Software says it is working on a way for the new owner to request the transfer themselves. If you are still stuck after these steps, email premium@givenergy.co.uk with Log In as the subject. GivEnergy Software aims to reply within 14 days.
Until the account is transferred to you, 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.
Go to givenergy.cloud/account-settings/security, the address GivEnergy Software gives for removing a connected service. 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.
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.
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 own hotspot (named with the dongle's serial number: a W followed by letters and numbers), 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.
Nine times out of ten this is connectivity, not a hardware fault. The system usually keeps running, but offline doesn't prove it, so check the inverter's own screen. Start with the KB-documented WiFi checks above; if you are still stuck, contact STS and we can set it up on site, from £195. If the signal doesn't reach, a WiFi extender is an extra £75, and we carry them with us.
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. A flashing green light is waiting mode, which is normal. Red means a fault that needs investigating: note the colour, then check the event log (app: device > Event History; portal: My Inverter > Event Log) and any fault code on the screen. See the red status light guide.
On LV GivBat batteries (51.2V), inverter-to-battery comms are RS485, not CAN, with master/slave addressing set via dip switches. Gen 1 inverters and batteries take a separate data cable on a green pin connector. Gen 2 and Gen 3 batteries are on a plug: one plug-in cable carries power and comms from the battery. At the inverter end, the comms go into an RJ45 BMS port on Gen 2 and a plug on Gen 3. On Gen 2, the commonest fault we see is the thick BMS comms cable crimped straight into the RJ45 plug. On an inherited system, also check the addressing: it may have been set for the original stack before a battery was moved. BMS Comm Fail guide.
On a hybrid inverter, EPS only powers the circuits wired to its EPS terminals, within that terminal's 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. The Gen 1 All-in-One (6kW and 3.6kW models) has no EPS terminal. With a Giv-Gateway it backs up the whole home (6kW continuous); without one it cannot supply the home in a power cut. The AIO 2 + MPPT is rated 12kVA off-grid. Inherited systems often have backup untested for years. EPS guide · Gateway 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 cloud integration left by the previous owner, such as a tariff provider, is rewriting your schedule. Local tools such as GivTCP may not appear in the log. Remove unknown access at givenergy.cloud/account-settings/security. KB: "Why Are My Charge Settings Changing Themselves?".
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).
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.
Since May 2026, GivEnergy's remote monitoring needs GivEnergy Premium (£4.99 a month). The free Standard tier of the GivEnergy app still works on your home network, with no subscription and, since app version 4.0.5, no login: live power flow, battery charge, meter totals and local control of the inverter. It does not show historic graphs. If you want history or automation without Premium, third-party tools can read the inverter directly over your home network. These are engineering projects rather than a single download, and entirely optional while the cloud runs.
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.
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.
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.
