GivEnergy All-in-One 3.6kW – 13.5kWh: The Flexible Home Battery System for Smarter, Resilient Energy Use

The GivEnergy All-in-One 3.6kW is a fully integrated battery storage solution that combines a 3.6kW AC inverter with 13.5kWh of useable energy storage. Built with modular design and robust performance in mind, it’s engineered to simplify installation, improve flexibility and maximise savings in modern British homes.

Whether you’re storing excess solar, charging off-peak via a flexible tariff, or preparing for outages, this system is ready to futureproof your energy setup. For full whole-house backup, pair it with the GivEnergy Gateway and continue powering your property even during grid failures.

All-in-One Simplicity, High Performance

This unit eliminates the need for separate inverters and battery modules by combining everything in one weatherproof, compact enclosure. With 3.6kW of continuous power and 13.5kWh capacity, it’s capable of supporting high-load appliances and extended usage windows.

• 3.6kW on-grid output with up to 6kW off-grid
• Integrated battery management and inverter
• IP65-rated for indoor or sheltered outdoor installation

Modular Battery Design for Easier Handling

The 13.5kWh battery is built with four removable modules, making installation more manageable and enabling easier service or upgrades in future. Each unit operates at 100% depth of discharge and uses high-efficiency LiFePO₄ chemistry for longevity and safety.

Its modularity also opens up multi-unit parallel installations (coming soon), offering potential for scaling systems up as your energy needs grow.

Smart Control and Connectivity

Connectivity is seamless, with WiFi, LAN and optional 4G onboard. The GivEnergy monitoring app and web portal provide real-time visibility, remote scheduling, and system diagnostics. It also includes RS485, CAN and LoRa interfaces for grid metering, EV charging or integration with smart home controls.

Designed for Smart Tariffs and Grid Services

The AIO 3.6kW is fully compatible with flexible and agile energy tariffs. Users can charge the battery at night when rates are lower and discharge during the day to avoid peak costs. It also supports participation in grid services schemes, where users may receive incentives for reducing consumption during peak demand windows.

This makes the unit not only a great fit for solar storage, but also for energy arbitrage and savings even without PV installed.

Whole-Home Backup (Optional with Gateway)

When paired with the GivEnergy Gateway, the system can provide seamless off-grid functionality in the event of a power cut. Switchover occurs in milliseconds, supplying power to the entire property or a designated backup circuit. With a peak off-grid output of 7.2kW, the unit can comfortably support demanding appliances like fridges, pumps, and broadband routers.
