GivEnergy is a Newton Abbot, Devon-based manufacturer offering a complete single-brand home energy stack: an EV charger, the All in One battery (13.5 kWh with integrated inverter), the Gen 3 Hybrid Inverter for modular installs, and a Gateway for whole-home energy management and backup power. Everything is monitored through the GivEnergy Cloud portal and app.
For the full UK home energy context, see our home energy ecosystem pillar guide.
What is the GivEnergy ecosystem?
GivEnergy was founded in 2017 and manufactures from Newton Abbot in Devon, giving it a UK-made credentials story alongside myenergi. Its ecosystem philosophy is single-brand depth: the charger, battery, inverter, and cloud portal are all designed to work together rather than as standalone products.
The GivEnergy Cloud is the central nervous system of the ecosystem. It provides a unified dashboard for monitoring solar generation, battery state of charge, grid import and export, and EV charging history. Critically, the Cloud API is publicly documented, which means technically-minded users and third-party developers can integrate GivEnergy data with platforms like Home Assistant, Zapier, or custom automations without waiting for official integrations.
GivEnergy’s product family includes:
- EV charger (7.4 kW smart charger)
- All in One (AIO) — combined battery and inverter unit
- Gen 3 Hybrid Inverter — standalone hybrid inverter for modular installs
- Gateway — energy management and backup power device
GivEnergy EV Charger
The GivEnergy EV charger is a 7.4 kW smart charger designed to integrate directly with the GivEnergy portal. It includes solar integration modes (Solar Boost and Eco) that use data from the GivEnergy system to modulate charging based on available solar surplus.
Key specifications:
- Output: 7.4 kW (single-phase 32A)
- Connector: Type 2 (tethered or universal socket)
- Solar Boost mode: charges preferentially from solar surplus detected via CT clamp
- Eco mode: modulates between minimum charge and available surplus
- O-PEN (Open Protective Earth Neutral) protection built in
- OZEV chargepoint grant approved
The charger integrates with the GivEnergy portal for scheduling and monitoring, meaning your EV charging history sits alongside your battery state of charge and solar generation in a single dashboard. For solar EV charging comparisons across brands, see our best solar EV chargers UK guide.
All in One (AIO) battery
The GivEnergy All in One is the product most people associate with the brand. It combines a 13.5 kWh lithium iron phosphate (LFP) battery with a 6 kW hybrid inverter in a single IP65-rated outdoor unit — meaning it can be mounted externally on a wall or in an exposed outbuilding without requiring indoor housing.
AIO specifications:
- Usable capacity: 13.5 kWh (LFP chemistry)
- Inverter output: 6 kW continuous
- Form factor: single combined unit, outdoor-rated IP65
- Warranty: 12 years (manufacturer warranty; verify current terms)
- Round-trip efficiency: typically 95%+
The IP65 rating is a practical advantage in UK climates. Many competing batteries are designed for dry indoor installation (garage or utility room); the AIO can go outside on a south-facing wall, saving internal space.
The 12-year warranty is one of the longer standard warranties in the residential UK battery market. Most competing products offer five to ten years. Confirm the current warranty terms before purchase as these are periodically updated.
Gen 3 Hybrid Inverter
The Gen 3 Hybrid Inverter is GivEnergy’s modular inverter, for households who prefer to specify their battery and inverter separately rather than using the integrated AIO. It is DC-coupled, handling both solar panel input and battery charging and discharging on the DC side before conversion to AC for home use.
Gen 3 variants:
- 3.6 kW, 5.0 kW, 6.0 kW output versions
- Supports DC-coupled solar PV and DC-coupled battery
- G98/G99 compliant for DNO connection
- Pairs with GivEnergy’s separate battery modules (as opposed to the AIO)
DC coupling is more efficient than AC coupling for brand-new solar-plus-battery installations, because energy does not need to be converted from DC to AC and back again before storage. However, it is harder to retrofit alongside an existing solar installation with a different inverter — in that case, the AC-coupled AIO or a separate AC battery product is the more practical option.
Gateway and GivEnergy Cloud
The GivEnergy Gateway is the whole-home energy management device that ties the ecosystem together. It provides:
- EPS (Emergency Power Supply): Backup power to selected circuits if the grid fails. The Gateway can island the home from the grid during an outage and use the AIO battery to maintain supply to critical loads.
- Energy flow management: Coordinates grid import, solar generation, battery state, and EV charging through the GivEnergy Cloud.
- Open API access: The GivEnergy Cloud API is publicly documented, making it compatible with Home Assistant and other home automation platforms. A well-maintained community integration (britkat1980/ha-givenergy on GitHub) provides Home Assistant users with real-time monitoring and control.
The open API is a meaningful point of difference. Most competing ecosystems (myenergi, Ohme, Hypervolt) have more limited third-party integration options, or provide API access only on request. GivEnergy’s public API allows advanced users to build automated battery scheduling, export optimisation, and demand-response automation outside the GivEnergy portal.
How it all works together
GivEnergy’s DC-coupled architecture creates an efficient energy flow for new solar-plus-battery installations:
- Solar panels generate DC electricity
- The Gen 3 inverter (or AIO) determines whether to use DC power immediately, store it in the battery, or convert and export to the grid
- The EV charger draws from the system, prioritising solar surplus or overnight battery discharge
- The GivEnergy Cloud portal schedules overnight grid charging of the battery during cheap tariff windows
- The Gateway manages export, EPS, and backup load prioritisation
Because DC power from the panels goes directly to the battery without conversion losses, the round-trip efficiency from generation to battery to home use is slightly higher than AC-coupled systems. For new builds where solar, battery, and inverter are all installed simultaneously, this efficiency advantage is real and measurable.
Tariff integration
GivEnergy does not currently hold native API partnerships with Octopus Energy in the way that Ohme and Hypervolt do. Instead, tariff integration is handled through manual scheduling in the GivEnergy Cloud portal.
Tariff compatibility:
| Tariff | Integration method |
|---|---|
| Octopus Flux | Manual schedule in GivEnergy Cloud; export arbitrage works well |
| Octopus Intelligent Go | Manual schedule; set charge window to 23:30–05:30 |
| Octopus Agile | Manual or third-party automation (Home Assistant via API) |
| OVO Charge Anytime | Manual schedule |
For Agile users with technical capability, the open API enables automated scheduling based on half-hourly rate data. The community Home Assistant integration supports this. For standard users, Octopus Flux with manual scheduling is the strongest match for a GivEnergy system with solar and battery.

Frequently Asked Questions
What is in the GivEnergy ecosystem? The GivEnergy ecosystem comprises an EV charger, the All in One battery-plus-inverter unit (13.5 kWh, 6 kW), the Gen 3 Hybrid Inverter for modular installations, and the Gateway for whole-home energy management and emergency backup power. Everything is monitored through the GivEnergy Cloud portal, which includes a publicly documented API for third-party integrations.
How big is the GivEnergy All in One battery? The All in One provides 13.5 kWh of usable capacity paired with a 6 kW continuous inverter output in a single IP65 outdoor-rated unit. This is sufficient for most UK households to cover evening and overnight consumption while retaining reserve capacity for morning EV charging.
Is GivEnergy better than Tesla Powerwall? The comparison depends on priorities. GivEnergy’s AIO is UK-made and typically less expensive per kWh than the Powerwall 3, with a similar 12-year warranty. The Powerwall 3 offers a slightly higher inverter output (11.5 kW peak), a more established brand name, and the broader Tesla ecosystem. GivEnergy’s open API is generally a stronger proposition for home automation users.
Does GivEnergy work with Octopus? GivEnergy is compatible with Octopus tariffs, including Flux and Intelligent Go, through manual scheduling in the GivEnergy Cloud portal. There is no native Octopus API partnership for automatic scheduling as of 2026. However, users with technical capability can use the open GivEnergy API and a Home Assistant integration to automate scheduling based on Agile or Flux rate data.
Can I add a GivEnergy battery to existing solar? Yes, via two routes. The Gen 3 Hybrid Inverter can be installed alongside new or existing solar in a DC-coupled configuration — this typically requires changing or supplementing the existing inverter. Alternatively, GivEnergy offers AC battery options that couple to the AC side of your system and work with any existing inverter. An approved GivEnergy installer can advise on the right approach for your setup.
