GivEnergy Review: Batteries, Inverters & Cloud App

GivEnergy built a strong UK reputation on competitive pricing, the GivEnergy Cloud app, modular All-in-One design and a 12-year battery warranty. The hardware is well-regarded and existing systems continue to operate. However, GivEnergy Ltd has entered administration, so for new purchases we no longer recommend specifying GivEnergy. The strongest currently-trading alternatives are Tesla Powerwall 3, Sigenergy SigenStor and FoxESS.

GivEnergy batteries are warranted for 12 years or 6,000 cycles, with a guarantee of at least 70% retained capacity. In practice, LiFePO4 batteries can last 15 to 20 years. A typical UK home cycles the battery once per day, so 6,000 cycles works out at roughly 16 years of use.

Yes. GivEnergy Cloud has native integration with Octopus Energy tariffs including Agile, Intelligent Go, and Flux. The system can automatically charge from the grid during cheap overnight periods (as low as 7p/kWh) and discharge during expensive peak periods (30p to 40p/kWh), maximising savings even on cloudy days.

GivEnergy can be retrofitted to most existing solar PV systems. If you have a standard string inverter, you can either replace it with a GivEnergy hybrid inverter or use an AC-coupled GivEnergy battery. If you already have a GivEnergy inverter, adding battery modules is plug-and-play.

GivEnergy is typically £2,000 to £3,000 cheaper than Tesla Powerwall for comparable usable capacity. GivEnergy offers a longer warranty (12 vs 10 years) and a better monitoring app. Tesla Powerwall offers higher single-unit capacity (13.5 kWh) and simpler backup power. Both are excellent choices for UK homes.

GivEnergy and Huawei Luna are similarly priced. Huawei Luna is the natural choice if your installer already uses Huawei inverters (the most common in the UK). GivEnergy has a better monitoring app and longer warranty (12 vs 10 years). Both use modular designs allowing future expansion.

Some GivEnergy systems support Emergency Power Supply (EPS) mode, which can provide limited backup power during grid outages. This requires an EPS switch to be installed at the time of installation. Not all models support full whole-home backup, so check with your installer.

GivEnergy Cloud is the free monitoring and control platform for all GivEnergy products. It provides real-time energy flow visualisation, historical data, remote battery control, smart tariff scheduling, and an open API for smart home integration. It is available as a web portal and mobile app (iOS and Android).

Yes. GivEnergy batteries qualify for 0% VAT when supplied and installed alongside solar PV panels under the same contract. If you add a GivEnergy battery to an existing solar system under a separate contract, standard 20% VAT applies.

GivEnergy is a UK company headquartered in Newcastle upon Tyne, but the batteries and inverters are manufactured in China. Design, software development, testing, and customer support are all based in the UK. This is standard practice across the solar battery industry.

Yes. GivEnergy batteries are modular. You can add 2.6 kWh or 5.2 kWh expansion modules to your existing system, up to approximately 15.5 kWh per inverter. Expansion modules cost £1,200 to £1,600 installed and use the same LiFePO4 chemistry with a 12-year warranty.

A typical UK household with a 5 kWh GivEnergy battery and solar panels can save £350 to £500 per year on electricity bills. With smart tariff integration (e.g. Octopus Agile), savings can reach £500 to £700 per year. Payback period is typically 8 to 12 years depending on usage patterns and tariff.

GivEnergy Ltd has entered administration. Existing batteries, inverters and All-in-One units continue to operate, and the GivEnergy Cloud platform at givenergy.cloud is still online at the time of writing. Manufacturer warranties become an unsecured claim against the administrator unless a buyer takes over the brand and honours them. Your installer and your consumer-code scheme (RECC or HIES) are your first lines of recourse.

The GivEnergy login and customer portal live at givenergy.cloud. The same credentials work in the GivEnergy iOS and Android apps. If you cannot log in, try a password reset first; if that fails, the issue is likely platform-side and your data will resync once the service is restored.

The GivEnergy app continues to communicate with the GivEnergy Cloud servers and your inverter via the GivEnergy Wi-Fi dongle. Most 'app not working' or 'inverter offline' reports are local connectivity issues, so check the dongle's status LED and your home router first. Owners who want monitoring independent of the cloud can use Home Assistant or Node-RED via GivEnergy's open API.

For new installations the strongest currently-trading alternatives are Tesla Powerwall 3 (best for whole-home backup and large single-unit capacity), Sigenergy SigenStor (closest spiritual successor, with a modular hybrid inverter, battery, gateway and EV charging in one ecosystem) and FoxESS (best like-for-like price point for a hybrid inverter plus stackable battery). Avoid specifying GivEnergy for new builds while the company is in administration.

The original GivEnergy All-in-One combined a 3.6 kW (5.2 / 8.2 kWh) or 6 kW (9.5 kWh) hybrid inverter and a LiFePO4 battery in a single wall-mounted unit. The All-in-One 2 / AIO Gen 2 added higher continuous output, refined thermal management and updated firmware. Both are LiFePO4 with a 12-year warranty; both depend on GivEnergy Cloud for smart-tariff scheduling, which is the main risk during administration.

A GivEnergy 9.5 kWh battery, typically supplied as the All-in-One 9.5 kWh with a built-in 6 kW hybrid inverter, was £5,800 to £7,000 fully installed in the UK at 0% VAT alongside solar PV. The Gen 3 9.5 kWh module sits at the top of GivEnergy's modular stackable range. Equivalent capacity in Tesla Powerwall 3 (13.5 kWh) is £7,500 to £9,500 installed.

A GivEnergy 5.2 kWh battery installed as part of an All-in-One 5 kWh package was £4,500 to £5,500 fully installed at 0% VAT alongside solar PV. As a stackable expansion module added to an existing GivEnergy hybrid inverter the same battery typically cost £1,800 to £2,400 installed.

GivEnergy did not sell a single 13.5 kWh unit; equivalent capacity was reached by stacking modular batteries (e.g. 9.5 kWh + 5.2 kWh, or 2× 5.2 kWh + 2.6 kWh) on a hybrid inverter, up to roughly 15.5 kWh per inverter. If you want a true single 13.5 kWh unit, Tesla Powerwall 3 is the closest off-the-shelf alternative.

The GivEnergy Wi-Fi dongle is the small adapter that plugs into the inverter or All-in-One and connects it to your home Wi-Fi and the GivEnergy Cloud. The GivEnergy gateway is a separate device used to coordinate multi-battery, multi-inverter and EV-charger setups (and EPS / backup switching). Both are required for full Cloud functionality and smart tariff automation.

GivEnergy's stackable batteries are modular LiFePO4 units (typically 2.6 kWh or 5.2 kWh) that physically stack and connect to a GivEnergy hybrid inverter. You can start small and add modules later, up to around 15.5 kWh per inverter, without replacing the inverter.

MCS-certified solar installers across the UK still service GivEnergy systems: diagnostics, expansion modules, dongle replacement, EPS commissioning and firmware. New 'GivEnergy approved' status is less meaningful while the company is in administration; prioritise an MCS-certified installer registered with RECC or HIES, regardless of brand affiliation.

During administration, the original GivEnergy customer-service number may route to the appointed administrator. The fastest route to a resolution for warranty or service issues is your original installer first, then your consumer-code scheme (RECC or HIES), then a Section 75 claim with your credit-card provider if you paid that way.

We do not recommend specifying a new GivEnergy battery, hybrid inverter or All-in-One in 2026. The hardware is good and existing systems will keep working, but new buyers face uncertainty around manufacturer warranty, firmware updates and the long-term future of GivEnergy Cloud. For new installations, lead with Tesla Powerwall 3, Sigenergy SigenStor or FoxESS instead.
