AEG Solarcube 14.4 kWh
AEG Solarcube 14.4 kWh - the plug-and-play home battery, backed by 10 years.
14.4 kWh plug-in plug and play home energy storage battery - no electrician, no rewiring, no MCS / DNO paperwork.
Save up to £800 a year.
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 £800 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.
Modular up to 14.4 kWh
Comes fully expanded at 14.4 kWh for maximum storage capacity. No need to replace the base unit - just stack and plug in.
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)
1. Plug in
Plug into any standard grounded UK socket, indoors or out.
2. Octopus ready
Can read live Octopus tariff without a dongle or clamp. For other energy providers, pair your smart or non-smart meter via a dongle, clamp, or HomeWizard bridge.
3. Save automatically
The Solarcube learns your tariff and your household pattern, charging cheap and discharging at peak without you lifting a finger.
