AEG SolarCube 14.4 kWh Home Energy Storage System
AEG SolarCube 14.4 kWh - the plug-and-play home battery, backed by 10 years.
1xHost and 3x4.8 kWh plug-in plug and play home energy storage battery - no electrician, no rewiring no MCS / DNO paperwork.
Cut your electricity bill without touching your meter box. The AEG SolarCube is a true plug-in home battery - lift it into place, plug it into a standard 13A socket, pair it with your smart meter, and start storing cheap off-peak power for the hours when prices spike.
It works seamlessly with solar panels, or stands entirely on its own on a dynamic tariff like Octopus Agile, Flux or Cosy.
German-engineered, LFP-safe and protected by a 10-year warranty.
Key benefits
- True plug-and-play setup - Out of the box to operational in under 30 minutes via a standard grounded UK socket. No electrician, no rewiring, no waiting list.
- The perfect retrofit for existing solar - Already have a string inverter or non-hybrid microinverter setup? You don't need to rip it out or swap to a hybrid. The SolarCube is AC-coupled, so it sits alongside your existing inverter and simply plugs into a socket. The fastest, lowest-friction way to add storage to a system that was never designed for a battery.
- Save up to £1000 a year - Charge when wholesale prices dip (often below 10p/kWh on smart tariffs), discharge during the 4–7pm peak when grid power can exceed 24p/kWh. Compatible with every major UK dynamic tariff.
- 6,000+ cycle life, 10-year warranty - Built on LiFePO4 chemistry: thermally stable, cobalt-free, and rated for well over a decade of daily cycling. Peace of mind, written down.
- IP65 rated - indoor or outdoor install - Fully dust-tight and weather-sealed, with an operating range of -20°C to +55°C. Mount it in the utility room, the garage, or outside under a canopy or eaves. We recommend siting it sheltered from direct rain and full sun to keep the housing looking factory-fresh, but the electronics are protected either way.
- 14.4 kWh - maximum power.
- Backup power when the grid goes down - A dedicated off-grid output of up to 2,400 W keeps lights, broadband and the fridge running through outages.
- A name you already trust - AEG: German electrical engineering since 1883
How it works (3 steps)
- Plug in - into any standard grounded UK socket, indoors or out.
- Octopus ready. Can read live octopus tariff without a dongle or clamp. For other energy providers pairs your smart/ non-smart meter via a dongle/clamp or HomeWizard bridge
- Save automatically - the SolarCube learns your tariff and your household pattern, charging cheap and discharging at peak without you lifting a finger.
