Charge

The battery charges from one of two sources — surplus solar generation during the day (when the panels are producing more than the house is using), or cheap overnight electricity from the grid (Octopus Agile, Cosy, or any time-of-use tariff). The All-in-One's AI-driven scheduler picks the right source based on the tariff, the weather forecast, and the household's expected evening load. No homeowner intervention needed.

Discharge

When the grid is expensive — typically 4 PM to 7 PM on a UK weekday — the battery discharges to power the home. 6 kW nominal AC is enough to run a heat pump, an induction hob, the oven, the lights, the TV, the laptops, and a slow EV charger simultaneously. 7.2 kW peak for 10 seconds handles motor startup loads. The home runs on stored electricity, not grid electricity, for the expensive hours.

Bridge

If the grid fails — storm, transformer fault, planned maintenance — the Giv-Gateway switches the home from grid power to battery power within 20 milliseconds. That's fast enough that lights don't flicker, fridges don't restart, and computers don't reboot. The home keeps running on the 13.5 kWh stored in the battery for approximately 10 hours of typical household load.

AC-couple

The All-in-One contains its own inverter — the box is both battery and inverter in one. That means it AC-couples to the home's existing electrical system rather than requiring a hybrid solar inverter swap. Already have a Solis, Fronius, SolarEdge, or Sungrow PV inverter? The All-in-One sits alongside it on the same consumer unit. No solar system rip-out required for the retrofit.

Export

When the battery is full and the panels are still producing, surplus exports to the grid under the Smart Export Guarantee at up to 15p/kWh. Octopus Outgoing Agile pays a half-hourly variable rate that peaks at 30p+/kWh on summer evenings — at which point the battery can discharge to grid at a profit. Same hardware, two different revenue streams depending on the tariff.

Cycle

A full charge-discharge cycle moves 13.5 kWh of energy through the battery. Lithium iron phosphate (LiFePO4) cells handle 6,000+ full cycles before measurable capacity loss — at one cycle per day, that's a 16-year working life. The battery management system (BMS) balances every cell on every charge, keeps temperature within the operating window, and reports cell health to the cloud for predictive maintenance.

Capacity 13.5 kWh Usable capacity at 100% depth of discharge. Every kWh of the rated capacity is available to the home — no derating for end-of-warranty performance.

AC Nominal 6.0 kW Continuous AC output. Enough to run a heat pump, induction hob, oven, lights, and slow EV charge simultaneously. 7.2 kW peak for 10 seconds handles motor inrush from compressors and pumps.

Peak Power 7.2 kW · 10 s Short-duration peak output: 7.2 kW for 10 seconds, 6.5 kW for 30 seconds. Covers compressor startup on heat pumps and air conditioners, motor inrush on fridges and pumps, and brief multi-load peaks.

DC Voltage 260–346 V Internal battery DC voltage range. 307 V nominal at the cell stack — the inverter handles all DC-AC conversion internally; no external high-voltage DC exposed at install.

DoD 100% Depth of discharge. 100% means the full 13.5 kWh is usable energy — unlike older NMC or lead-acid systems where rated capacity is 110–120% of usable to extend cell life.

Cell Chemistry LiFePO4 Lithium iron phosphate — the safest commercial battery chemistry. Won't thermal runaway. Class A1 fire rating to IEC 62619. Suitable for indoor utility-room installation in domestic property.

Switchover ≤ 20 ms Grid-to-battery transfer time with Giv-Gateway. Fast enough that lights don't flicker, electronics don't reboot, fridges don't restart. True uninterruptible power supply for the whole home.

Dimensions 1100 × 600 × 280 mm Height × width × depth in millimetres. Wall-mounted enclosure designed to clear a standard 600 mm deep utility cupboard. Mounting bracket included.

Weight 173.7 kg Total unit weight. Wall mounting requires structural masonry or a properly fixed timber-frame stud wall — verified by the engineer at fit day. Lifting requires two installers plus a battery lift trolley.

IP Rating IP65 IP65 weatherproof — installs indoor (utility, garage, plant room) or outdoor (side return, weatherproof wall). Dust-tight and protected against low-pressure water jets. Continuous outdoor exposure rated for the 12-year warranty life.

Cooling natural · no fans Natural convection only — no fans, no moving parts to wear or fail. Heat dissipates through the enclosure walls at the inverter's continuous power rating. Maintenance-free for the warranty life.

Noise < 30 dB Below 30 dB at one metre — quieter than a library reading room. Fan-cooled batteries (especially under heavy load) typically run at 45–55 dB. The All-in-One is silent enough to install in a hallway or under a stairwell.

Operating −10 → +50°C Operating temperature range. The system charges and discharges across normal UK indoor and outdoor temperature variation without derating. Cell temperature managed internally by the BMS.

Certification G99 · IEC 62619 · CE G99-certified for installation at 6 kW nominal. The 3.6 kW variant of the same product is G98-certified — installs without prior DNO permission, useful in areas with grid-supply constraints.

GivEnergy app · iOS / Android

Live view of battery state of charge, solar generation, home consumption, grid import and export — all on one screen. Set charge and discharge schedules, view savings, check warranty status. The single account covers multiple sites — useful for landlords, multi-property owners, and CleverBloom service plan visibility.

Octopus Agile integration

Direct API integration with Octopus Energy's half-hourly Agile tariff. The system reads the next 24 hours of pricing, charges from the grid during the cheapest 4–6 hours overnight (typically 11 PM to 5 AM), and discharges through the expensive evening peak. Saves about £400–£700 per year over a flat tariff, depending on consumption pattern.

EPS whole-home backup

Paired with the Giv-Gateway, the system delivers Emergency Power Supply (EPS) for the entire home — not just a few essential circuits. 20 ms switchover keeps lights on, internet routers connected, fridges running. Critical for home offices, families with medical equipment, or remote properties on overhead supply.

Solar-priority charging

When solar is producing, the system prioritises charging the battery before exporting. Set a daily SoC target (e.g. 80% by 4 PM) and the AI schedules grid top-up only if solar won't get there. Maximises self-consumption — typically 75% of solar generation stays on-site instead of exporting at 5–15p/kWh and re-importing at 25–30p/kWh.

EV charger coordination

When a paired EV charger (OCTA Wall, Zappi, Andersen) is drawing power, the system avoids discharging the battery into the car — that's an inefficient double conversion. Instead, it routes solar surplus or cheap grid directly to the car, keeps the battery for the home's evening load. Configurable load priority via the app.

Real-time energy monitor

Live kWh visibility for every circuit the system meters — battery, solar, grid, home consumption. Compare seasons, identify the appliances and schedules that drive consumption, see exactly where the savings are coming from. Particularly useful in the first three months after install to validate that the system is performing as quoted.

Remote diagnostics by GivEnergy

GivEnergy monitors connected units remotely from their service centre in Stoke-on-Trent. Most warranty cases can be diagnosed without a site visit — cell voltages, temperatures, inverter performance all visible to the manufacturer. Faster fixes, lower service cost, longer system life. UK-based support, UK office hours, UK manufacturing for parts.

Cloud connected · OTA updates

Wi-Fi, LAN, and optional 4G connectivity to the GivEnergy cloud. Firmware updates pushed over-the-air — inverter logic, app features, tariff integrations all upgrade automatically. The unit you buy this year keeps getting better through its 12-year warranty life. Recent OTA additions include Octopus Cosy and Intelligent tariffs, plus new EV-charger coordination logic.

Multi-unit parallel

Up to six All-in-One units can run in parallel for systems up to 80 kWh. For homes with very high consumption (heat pump + EV + home office), the Expansion Battery (matching 13.5 kWh module without inverter) extends the main unit to 40.5 kWh on a single inverter — lower cost-per-kWh than parallel inverters. Both architectures supported.

01 Phone chat Free · phone or video Discuss your home, current electricity bill, existing solar system (if any), electricity tariff, and whether you want lower bills, tariff optimisation, EPS backup, or all three. We confirm the right battery size (13.5 kWh for most 3-bedroom homes, 9.5 kWh for smaller properties) and provide a fixed-price quotation within 48 hours, including DNO notification and 0% VAT.

02 Fit day 1 day on site Engineer completes final electrical checks, including mains supply, consumer unit capacity, battery mounting location, Gateway position, Wi-Fi signal, and CT clamp placement. The battery and Gateway are installed, wired between the meter tails and consumer unit, commissioned, paired with the homeowner's app, and the DNO G98 notification is submitted the same day.

03 How to use 1 hour on handover We walk you through the mobile app, explain battery charging and discharging, Agile tariff scheduling, and demonstrate EPS backup operation where installed. Warranty registration is completed, documentation is handed over, and aftercare support is available throughout the first heating season.

1 · All-in-One main unit

The integrated battery and inverter cabinet. 1100 × 600 × 280 mm wall-mounted enclosure, 173.7 kg total. Contains four 3.375 kWh LiFePO4 battery modules, the AC-coupled inverter, the battery management system, and the cloud-connected control board. IP65 weatherproof — installs indoor (utility, garage) or outdoor (side return, weatherproof façade).

2 · Giv-Gateway

The companion unit that enables whole-home backup. Sits between the grid supply and the consumer unit, switches the home from grid to battery within 20 ms when the grid fails. Includes a connection point for solar PV input so the panels keep generating during a grid outage. Required for EPS — without it, the All-in-One is grid-tied only.

3 · Battery management system

The BMS lives inside the main unit. Monitors voltage, current, and temperature on every one of the 240+ LiFePO4 cells. Balances cells on every charge so all 13.5 kWh stays usable through the warranty life. Limits charge/discharge rate at cell-level temperature extremes. Reports cell-by-cell health to the cloud for predictive maintenance.

4 · CT clamp & metering

Current transformer clamp installed on the incoming grid tail at the consumer unit. Measures real-time house consumption and grid import/export. The system uses this data to decide when to discharge the battery, when to charge, and when to export. Pre-configured with WAGO connectors — no terminal screws, tool-free wiring.

5 · DC and AC isolators

Built into the main unit — no separate isolator cabinet required. AC isolator on the grid-side connection, DC isolator on the battery internal bus. Switchgear pre-installed and factory-tested. Reduces install time by a half-day compared with older modular battery systems where switchgear was installed and commissioned separately.

6 · Communication module

Built-in Wi-Fi, LAN, and optional 4G LTE connectivity. RS485 and CAN ports for integration with third-party energy-management systems, smart-home platforms, and EV chargers. LoRa optional for sites with no internet — useful for rural properties where Wi-Fi reliability is marginal.

12 year manufacturer warranty

GivEnergy warrants the All-in-One for 12 years from commissioning — one of the longest warranties in residential battery storage. Covers the battery cells (retained capacity), the inverter, the BMS, the enclosure, and the Gateway. Parts and labour included. UK-based warranty service via the GivEnergy Stoke-on-Trent office — no shipping to overseas service centres.

LiFePO4 cell chemistry

Lithium iron phosphate is the safest commercial battery chemistry. Won't thermal runaway under fault conditions — unlike NMC (the chemistry in most EVs and older home batteries), LiFePO4 doesn't release oxygen during thermal events. Critical for indoor installs where the battery sits in a utility room near sleeping occupants. Class A1 fire rating per IEC 62619.

6,000+ cycle life

Tested for 6,000 full charge-discharge cycles before measurable capacity loss. At one cycle per day, that's a 16-year working life — past the 12-year warranty. Most home use cases run 0.7–0.9 cycles per day (the battery rarely fully drains), pushing real-world lifespan to 20+ years. The cell chemistry is the limiting factor; the inverter and BMS are designed to outlast it.

UK-made · UK warranty

Designed and assembled in Stoke-on-Trent. Warranty service is handled by GivEnergy's UK team — no overseas shipping for repairs, no language barrier, no time-zone delays. Spare parts hold in UK stock for the 12-year warranty life. The single largest UK battery storage manufacturer at the residential scale.

SYSTEM PROTECTOR
Correct CT clamp position

The CT clamp is what tells the system how much the house is using right now. Wrongly positioned — on the load side of the consumer unit instead of the supply side, or facing the wrong direction — and the system misreads consumption and discharges into the grid instead of the house. A 30-second installer detail that determines whether the battery saves money or wastes it. Verified at commissioning.

SYSTEM PROTECTOR
Stable Wi-Fi or 4G uplink

The All-in-One needs cloud connectivity to read the Agile tariff, push OTA updates, and report cell health for predictive maintenance. A weak Wi-Fi signal at the unit location causes silent disconnects — the system stays operational but drops out of agile scheduling and stops earning the cheap-overnight saving. Optional 4G LTE backup module covers properties where Wi-Fi reliability is marginal.
