GivEnergy All in One: check the warranty and your UK quote

This guide covers UK Gen 1 GIV-AIO-AC-13.5, not All in One 2 or the 3.6 kW variant. Read the support warning below before relying on historic warranty claims, then confirm compatibility, total cost and who supplies and supports the system.

Which All in One is on your quote?

Check the model on both the nameplate and written offer; do not substitute another generation's figures or terms.

Documented UK Gen 1 All in One; verify the nameplate and offered components.
ModelGivEnergy All in One Gen 1; UK datasheet SKU GIV-AIO-AC-13.5. This is not All in One 2 or All in One 3.6.
Battery energy13.5 kWh usable battery-pack capacity in the UK sheet; nominal cell or design capacity is not separately stated. This is not annual delivered AC energy.
AC output6.0 kW continuous or nominal AC output. The manual limits the 7.2 kW peak figure to off-grid operation; it gives no peak duration here. The battery sheet's 25 A is DC current, not AC charging power.
ConnectionAC-coupled unit with a bidirectional inverter. The UK sheet states nominal 230 V AC; manual diagrams indicate a single-phase arrangement. Have the installer confirm your site's phase, existing PV inverter and metering.
BackupAdditional Giv-Gateway for the documented whole-home backup arrangement; do not assume it is included in a base on-grid quote.
Installation envelopeDatasheet: IP65, 1100 × 600 × 280 mm excluding feet, 173.7 kg. Have a qualified installer confirm the proposed location and applicable environmental limits against the exact model’s documentation.
Warranty labelThe datasheet advertised 12 years. The separate 13 February 2024 UK warranty overview describes a conditional 12-year term and 70% usable-capacity promise. It says the customer's formal legal warranty documentation is in their individual online account after commissioning. Neither source proves your applicable contract or current claim performance by GivEnergy Ltd.

What does the warranty document mean now?

Hardware and capacity terms

GivEnergy Ltd's 13 February 2024 document is a residential product warranty overview, not an individual customer's legal warranty. It describes conditional 12-year hardware and 70% usable-capacity terms. Formal documentation is held in the customer's online account and becomes valid only after completed commissioning; we have not inspected it. Neither document establishes that a claim will now be honoured. Read the support-status warning and request the named obligor and formal terms for your serial number and installation date.

Installer, seller and separate protection

Ask who warrants the installation work, which seller is responsible under your contract, and whether any insurance or separate scheme actually covers this product. Request the policy and exclusions rather than assuming a group company or asset purchaser assumed GivEnergy Ltd's old liabilities. The administrator recommends contacting the installer first. Individual rights depend on the contract and facts.

App, cloud and firmware

The licence names the separate GivEnergy Software Ltd. The April 2026 Energy Storage Association expectation that the app and portal would continue is not a future-service guarantee. See the dated warning above for the register status and 15 September notice; a strike-off proposal does not prove that service has stopped.

A software announcement proposed free local access and paid cloud functions for remote access, historical data, automation and API use. We did not verify current fees, full feature entitlements, firmware commitments, a replacement operator or long-term continuity. Request current written terms and confirm usable local functions; these are separate from hardware cover.

Will it fit your existing solar system?

An existing PV inverter may remain in the documented AC-coupled arrangement. The installer must assess the exact model, phase, metering, export and grid/DNO requirements, and commissioning. Gateway equipment is additional for the documented whole-home backup arrangement, not assumed in on-grid storage. Ask what stays and which backup scope is included; compatibility is not universal.

What is the full installed cost?

Compare the complete additional installed price with keeping your current solar. Itemise the unit, required inverter/control and metering pieces, chosen Gateway/backup work, electrical changes, installation, commissioning and mandatory charges. Separate recurring software, support, maintenance and protection costs. Verify the legal supplier, whether the unit is new and in stock, and who stands behind each term.

What can the calculator check?

The calculator compares your battery-addition assumptions with keeping the same solar without a battery. Capacity (13.5 kWh) and power (6 kW) are not first-year AC kWh delivered to home loads instead of grid purchases. Enter three user-chosen annual energy scenarios, not a forecast derived from capacity. The existing-solar guide explains this annual-use boundary.

Use the full additional installed cost, your horizon and life, and supported annual cost estimates. Whole-system AC efficiency relates home-delivered AC energy to otherwise-exported AC solar, including conversion and auxiliary losses; the manufacturer's efficiency is not automatically comparable. Avoided variable purchases are offset by export income forgone. Include expected subscriptions or maintenance without assuming an unknown fee is zero.

Administration risk, warranty recovery, app/cloud continuity, backup value, grid charging, dynamic tariffs, replacement, finance and physical timing are not modelled. Warranty duration does not set life or horizon; annual totals do not establish when charging and discharge can happen.

Questions to ask before accepting a quote

  • Which exact Gen 1 model, serial number or batch, condition and legal supplier are on the offer? Is the unit new and in stock?
  • What remains of your existing solar system? Which phase, metering, export, grid or DNO and commissioning arrangements are proposed, and which Gateway or backup parts are included?
  • What is the itemised additional upfront amount, and which software, support, maintenance or protection charges recur?
  • Who will honour hardware defects, usable-capacity terms and installation work? Which named party and documents apply to your serial number and installation date? What separate insurance, if any, covers this system?
  • Who currently operates the app and cloud, what local functions remain usable, what are the written price and firmware terms, and what happens if the proposed software-company strike-off proceeds?
  • What supports first-year AC home-delivered energy and a whole-system AC efficiency on the calculator's boundary? Which avoidable import rate and forgone export rate apply to your household?

Keep your quote and warranty documents together. Use the existing-solar quote checklist, then enter your own supported assumptions in the calculator. Ask the installer or seller to resolve any missing provider, component or service term before comparing offers.

Considering another system? Our UK comparison of Powerwall 3, SigenStor and SMILE-G3 covers configuration and quote checks; it is not a product ranking or a suitability assessment for your home. Keeping your existing solar system without a battery is also an option.
