If the words “home battery” make you picture a big, boxy piece of industrial hardware best left hidden, you’re in for a surprise. The Nex E6000 shatters that idea with an ultra-sleek, wall-mounted design — just 119.5 mm (about 4.7 inches) thick — and enough modern flair to earn a 2026 Red Dot Design Award. Far from an eyesore, it’s meant to blend right into your living space.
Measuring 842.5 x 500 x 119.5 mm (roughly 33.2 x 19.7 x 4.7 inches) and weighing 59 kg (around 130 lbs), it’s still no featherweight. You’ll want a load-bearing brick or concrete wall for mounting, and definitely a partner to help with the heavy lifting. While you could theoretically pull off a DIY installation, the manual recommends giving extra thought to wall strength, ventilation, and fire safety — in older homes especially, professional advice is strongly encouraged.
SAMDUO wants to democratize home energy storage with the Nex E6000’s promise of plug-and-play simplicity. While many batteries hook directly to solar panels, this one connects to your home’s AC circuit — just plug it into a standard wall outlet. That means it plays nicely with existing solar setups and you don’t need to rip out or modify your current installation. European homes — where space is often at a premium — can finally consider solar storage without battling for every square foot.
Of course, “without an electrician” isn’t quite the whole story. Physically hooking up the battery may be straightforward, but mounting a 59 kg object safely is another matter. So yes, it’s simple — unless you underestimate gravity. Once installed, though, things really start to shine.
With a storage capacity of 6,028 Wh (expandable up to 90 kWh with fifteen units) and stable, long-lasting LiFePO4 cells, the Nex E6000 is a robust choice for personal solar energy management. The battery can soak up your surplus solar power during the day and release it after sunset, covering your evening essentials — think lighting, your internet box, the fridge, laptop, and TV — for several hours.
Through the SAMDUO ecosystem, you can monitor your home’s energy flows in real time and easily configure when to charge and discharge:
This is where the smart software comes into its own, helping you automate for savings and flexibility. Its open API ensures smooth integration with energy meters, smart home platforms (like Home Assistant and Homey), and other automation tools — enthusiasts, consider yourselves invited.
With its approved simplified setup, the Nex E6000 delivers a network-linked output of up to 2,600 W. Important caveat: in grid-connected mode, you shouldn’t expect to run power-hungry appliances (oven, dryer, or your sauna ambitions) all at once. But for the essentials? You’re covered.
The Nex E6000 won’t transform your house into an off-grid fortress, but it can keep daily life running smoothly for several hours — no blackout-induced candle hunts required.
The price point (from 1,999 euros, or around £1,700 / $2,200 at the time of writing in France) strikes a balance between storage capacity, sleek looks, wall-friendly size, and the kind of plug-and-play intelligence that finally makes home storage accessible. Its main strength is making residential storage genuinely easy to implement, especially for existing solar homes.
In its current form, the Nex E6000 looks like a very promising solution for solar-equipped households, especially those looking to boost their self-consumption without overhauling their entire installation.
