GivEnergy All in One Review UK: 13.5kWh Specs and Warranty After Administration

The GivEnergy All in One is a 13.5kWh AC-coupled home battery with the inverter built into the same cabinet, and it is now an orphaned product. GivEnergy Ltd entered administration on 9 April 2026, so any GivEnergy All in One review written today has to cover two things: what the hardware does on paper, and what the administration means for the warranty. This guide does both, using GivEnergy's own datasheets. For the corporate story in full, see our GivEnergy administration guide.

GivEnergy All in One: the specs

Figures below come from GivEnergy's All in One datasheet (October 2023 issue, the version hosted on its Australian site, which covers the four models in the range). Check the exact revision your installer quotes.

• Battery: 13.5kWh capacity, 100% depth of discharge, LiFePO4 prismatic cells, 260–346V battery voltage range, maximum 25A charge or discharge.
• Four inverter ratings: the same 13.5kWh battery comes with a 3.6kW, 4.6kW, 5.0kW or 6.0kW inverter (model codes GIV-AIO-AC-13.5-3.6, -4.6, -5.0 and GIV-AIO-AC-13.5). Peak power for 10 seconds off-grid runs from 4.3kVA on the smallest to 7.2kVA on the 6kW unit.
• Efficiency: inverter maximum efficiency of 96.5%.
• Build: IP65 rating, operating range of −20°C to +50°C, typical noise below 30dB, natural cooling.
• Size and weight: 1,150 × 600 × 280mm and 195kg. An earlier datasheet for the original 6kW unit lists 173.7kg and a 1,100mm height, so the weight depends on the revision you are buying.
• Connectivity: Wi-Fi and LAN as standard, 4G optional, with monitoring through the GivEnergy app and portal.

The headline point is that the battery is AC-coupled: it connects to your home's AC wiring rather than to your solar panels' DC side. That makes it easy to add to an existing solar system, which is why it sold so widely as a retrofit. Our home battery installation guide explains what that means for the install and cost.

Which inverter size is right?

The battery is identical across the range, so the inverter rating only sets how much power the unit can deliver at once. A 3.6kW or 4.6kW unit is enough for a typical home that mainly wants to shift evening kettle, oven and heating loads. The 5kW and 6kW versions suit homes that run an electric shower, heat pump or EV charger at the same time as the oven. If you are unsure how much capacity you need in the first place, start with our guide to what size home battery you need.

Whole-home backup needs the Gateway

The All in One does not give whole-house backup on its own. GivEnergy sells a separate Giv-Gateway (GIV-AIO-GW1) which switches the home between grid and battery when the grid fails and gives a connection point for your solar to keep generating. Budget for it if backup matters. Our home battery backup guide covers what a battery can and cannot run during a power cut.

Warranty: read this before you buy

GivEnergy's datasheet lists a 10-year warranty, but the company that issued it is in administration. The terms, taken from GivEnergy's All in One warranty document (2024 issue, written for its Australian importer, so UK paperwork may differ in detail), are:

• Period: up to 10 years from installation, provided the unit is commissioned on the GivEnergy app or portal within 30 days of mounting or getting online.
• Throughput cap: unlimited throughput if the battery is charged only from solar; 135MWh of total throughput if other sources, such as the grid, also charge it.
• Capacity guarantee: the unit should keep at least 70% of its 13.5kWh capacity during the warranty period.
• Remedy: repair or replacement with new or refurbished goods, at the supplier's discretion.
• Connectivity: transferring the warranty to a new owner requires the unit to have been online at least 90% of the time since installation.

The practical problem is the one set out in our administration guide: the administrator stated that no further hardware warranties will be honoured by GivEnergy Ltd. A 10-year promise from a company that has stopped trading is not something to rely on. If you already own a unit, contact your installer, and check whether Section 75 of the Consumer Credit Act applies if part of the payment went on a credit card.

What about the app and the next generation?

The app and portal are run by GivEnergy Software Ltd, a separate company that was not placed in administration, so monitoring is not expected to be affected for existing owners. GivEnergy's website still lists the newer All in One 2, a 13.5kWh system that pairs with a Gateway 2 and a 13.5kWh expansion battery (up to 40.5kWh in total), but a product listing is not the same as a supplier standing behind it. We found no report of a buyer for the business, so check stock and warranty cover directly with any installer quoting either model.

Verdict: should you buy a GivEnergy All in One?

For a new install, we would not choose one unless the installer offers their own written warranty and spares backing. The hardware specification is competitive: 13.5kWh, full depth of discharge, a choice of inverter sizes and a sensible IP65 outdoor rating. But the manufacturer warranty, the main reason to pay for a 10-year product, currently has no one behind it. Compare it with in-stock alternatives in our best home batteries roundup, including the Tesla Powerwall 3, and see our GivEnergy AIO vs Powerwall 3 comparison and Fox ESS vs GivEnergy. Whatever you choose, get quotes from MCS-certified installers and ask for the warranty provider and terms in writing.
