GivEnergy All-in-One
The All-in-One (AIO) combines the hybrid inverter and battery storage into a single wall-mounted enclosure. Available in 2.6 kWh and 9.5 kWh configurations, it is designed for simpler installations where space is limited or a self-contained unit is preferred. Popular for retrofit installations where running separate cabling for a modular system is impractical.

Who it suits
GivEnergy Gen 3 Hybrid Inverter
The Gen 3 is GivEnergy's flagship single-phase hybrid inverter. Available in 3.6 kW, 5.0 kW, and 8.0 kW output ratings, it connects to external GivEnergy battery modules via a dedicated battery cable. The modular design allows battery capacity to be increased over time by adding additional battery modules — up to 47.5 kWh with five GivBat 9.5 Gen 3 units.

Who it suits
GivEnergy Battery Modules
GivEnergy lithium battery modules are the storage component of modular Gen 3 systems. They connect to the hybrid inverter via a CAN bus communication cable and a DC power cable. Multiple modules can be stacked — wall-mounted in a tower configuration — to build larger storage capacity. Each module contains its own Battery Management System (BMS) which manages cell balance, temperature, and safety.
GivEnergy battery module sizes
| Module | Capacity | Usable | Max modules |
|---|---|---|---|
| GivBat 2.6 Gen 1 | 2.6 kWh | 2.08 kWh (80% DoD) | Up to 5 |
| GivBat 5.2 Gen 1 | 5.2 kWh | 4.16 kWh (80% DoD) | Up to 5 |
| GivBat 8.2 Gen 1 | 8.2 kWh | 8.2 kWh (100% DoD) | Up to 5 |
| GivBat 9.5 Gen 2 | 9.5 kWh | 9.5 kWh (100% DoD) | Up to 5 |
| GivBat 5.12 Gen 3 | 5.12 kWh | 5.12 kWh (100% DoD) | Up to 5 |
| GivBat 9.5 Gen 3 | 9.5 kWh | 9.5 kWh (100% DoD) | Up to 5 |
Maximum stackable modules varies by inverter model and generation. Check your inverter specifications before purchasing additional batteries.
GivEnergy EV Charger
GivEnergy's EV charger integrates with the GivEnergy ecosystem via the portal, allowing solar and battery-powered EV charging. It can be configured to charge from excess solar, cheap overnight electricity, or battery storage — all managed through givenergy.cloud.
All-in-One vs Gen 3 — key differences
| Feature | All-in-One | Gen 3 Hybrid |
|---|---|---|
| Form factor | Single integrated wall unit | Inverter + separate battery modules |
| Battery scalability | Fixed — no external expansion | Scalable — add modules over time |
| Max storage | 9.5 kWh (AIO 9.5) | Up to 47.5 kWh (5 × 9.5 Gen 3) |
| Inverter output | 3.0 kW or 5.0 kW | 3.6 / 5.0 / 6.0 kW |
| Installation complexity | Simpler — single unit | More complex — separate components |
| WiFi dongle | AECC dongle | Gateway2 dongle |
| EPS backup | Yes | Yes |
| Best for | Compact, retrofit, fixed capacity | Expandable, high capacity, EV charging |

GivEnergy product questions
The All-in-One is a self-contained unit with the inverter and battery built into a single enclosure — simpler to install but with fixed capacity. The Gen 3 is a standalone inverter designed to connect to external battery modules — more complex to install but scalable, allowing you to add battery modules over time. If you plan to grow your storage capacity or have high energy usage, the Gen 3 modular approach is generally better long-term value.
Not with external modules in the same way as the Gen 3. The All-in-One is designed as a self-contained unit. If you want to significantly increase your storage capacity beyond 9.5 kWh, you would need to either add a second All-in-One unit or replace the system with a Gen 3 plus battery modules. This is an important consideration when choosing — if expansion is likely, the Gen 3 modular system offers a cleaner path.
Yes. GivEnergy systems work well with Octopus Go, Agile, Intelligent, Flux, and Cosy tariffs. For Go and fixed time-of-use tariffs, you set a Timed Charge window in the GivEnergy portal to charge during cheap-rate hours. For Agile with half-hourly variable pricing, GivTCP with Home Assistant can automate dispatch based on live prices. Some GivEnergy models have partial integration with Octopus Intelligent — check the Octopus app to see whether your inverter is listed as compatible.
GivEnergy inverters typically carry a 5-year warranty, with an optional extension to 10 years available at the time of purchase. GivEnergy battery modules typically carry a 10-year warranty with capacity retention guarantees. Warranty terms may vary by product generation and purchase date — check your installation documentation or GivEnergy's current terms for your specific product. An independent engineer report is recommended when making warranty claims to document the fault and support the submission.
Yes. GivEnergy also produces a compatible EV charger that integrates with the hybrid system, allowing you to charge an EV from solar surplus or from stored cheap-rate electricity. For large battery systems (20+ kWh), charging an EV from stored overnight electricity on a tariff like Octopus Go is a popular and cost-effective strategy. The Gen 3 with multiple battery modules is better suited to EV charging than the All-in-One due to its larger potential storage capacity.
