Detailed overview: Samduo Nex E6000 6 kWh AC-coupled plug and play solar battery
The Samduo Nex E6000 is a plug and play home battery coupled on the AC side. A LiFePO4 battery, a bidirectional inverter and battery management fit in a single case measuring 842.5 x 500 mm and 11.9 cm thick. It plugs into a socket with the supplied 1.5 m cable and Schuko plug and stores the surplus of an existing solar installation to release it later. There is no photovoltaic input: panels cannot be connected to it, it complements a system that is already tied to the grid. Samduo, a Chinese maker based in Shenzhen and a former white-label supplier, presents it as the slimmest residential battery on the market, a claim that is its own.
The 6028 Wh rest on LiFePO4 cells whose origin is not published, rated for at least 10,000 cycles, with a 10-year limited warranty that starts at activation. Charging reaches 2600 W from the AC side, but feed-in to the grid is limited to 800 W, the ceiling for plug and play systems. A dedicated off-grid backup port delivers 2600 VA continuously and 3640 VA for 10 seconds: appliances to keep running during an outage, such as the fridge, the router or the lighting, plug directly into it.
The Samduo app runs the system over 2.4 GHz Wi-Fi, Bluetooth or a network cable, with an RS485 port and an open API cited for Home Assistant and Homey. Optimisation around dynamic tariffs is announced, but the manual says it will arrive through future updates. The Smart Meter, a meter fitted in the consumer unit, measures household consumption and aims at zero feed-in: it is not in the box of the battery alone and is ordered separately (listed at £112 in the brand's UK shop), though some offers include it. Up to 15 units can be combined through PowerMesh, giving 90 kWh.
The unit stands upright, on the floor or on a wall with the supplied bracket, preferably brick or concrete, with 50 mm of clearance in front, above and at the sides. It is IP65, rated from -20 °C to 55 °C, and Samduo quotes under 25 dB. Allow for 59 kg to be handled by two people and a connection to an external earth point required by the manual (cable not supplied).
Samduo publishes an EU declaration of conformity and grid connection certificates issued by Bureau Veritas on 8 June 2026 (EN 50549-1 for France, VDE-AR-N 4105 for Germany). Keep in mind a brand that is only starting out in Europe, an unpublished round-trip efficiency and, to our knowledge, no complete independent measurement to date.

Comparison
Between roughly £1400 and £1725, the Samduo Nex E6000 compares with plug and play solar batteries in the 5 to 6 kWh class, targeted by searches such as "Nex E6000 vs Venus E 3.0" or "6 kWh plug and play solar battery". Here is how it sits against three references from the catalogue: the Marstek Venus E 3.0, the Anker Solix Solarbank 4 E5000 Pro and the EcoFlow Stream AC 5000.
| Criterion | Samduo Nex E6000 | Marstek Venus E 3.0 | Anker Solix Solarbank 4 E5000 Pro | EcoFlow Stream AC 5000 |
|---|---|---|---|---|
| Capacity | 6028 Wh (90 kWh with 15 units) | 5120 Wh (15.36 kWh with 3 units) | 5024 Wh (up to 30 kWh) | 5024 Wh (up to 15 kWh) |
| Direct solar input (MPPT) | No, AC-coupled | No, AC-coupled | Yes, 4 MPPT, 5000 W | No, AC-coupled |
| AC power | 2600 W charge and discharge, 800 W to the grid, 2600 VA backup | 2500 W bidirectional | 2500 W off-grid, 800 W fed in | Up to 3000 W, charge and discharge |
| Dimensions (mm) | 500 x 119.5 x 842.5 | 480 x 153 x 624 | 460 x 305 x 355 | 295 x 287 x 489 |
| Weight | 59 kg | 60 kg | 50 kg | 44.6 kg |
| Warranty | 10 years | 10 years | 10 years | 10 years |
| Observed price | £1723 (UK brand shop, currently sold out) | ≈ £1400 | ≈ £1699 | ≈ £1499 |
In short, the Samduo Nex E6000 stands out with its flat 11.9 cm case and the highest capacity in the table, with 90 kWh possible across a network of 15 units. The Marstek wins clearly on price, the EcoFlow on weight and AC power, the Anker on direct solar input and expandability. In return, the Samduo is the most expensive in the table, remains heavy at 59 kg and comes from a brand that is only starting out in Europe: a relevant choice for anyone who wants a slim, discreet unit against a wall, less so for anyone chasing the lowest price.

Our tester's review: Julien De Jurquet
We have not had the Nex E6000 in hand: this opinion rests on the manufacturer's data sheet, its manual and the tests published so far, in video and in the specialist press, some of them made in partnership with the brand. On paper the idea is appealing: 6 kWh, inverter and battery management in a case 11.9 cm thick, plugged into an ordinary socket without touching the existing solar installation. One published test notes a quick set-up, a pleasant app and discreet operation; Samduo claims under 25 dB, while one published reading puts it at 36.9 dBA against the casing. The reservations are real: a brand that has only just reached Europe and whose after-sales service is still to be proven, 59 kg, no solar input, only 800 W to the grid, a Smart Meter to add depending on the offer, an unpublished round-trip efficiency and a price above a Marstek Venus E 3.0. A serious candidate for anyone who wants a slim, discreet unit, to be confirmed by independent measurements.
Frequently asked questions: Samduo Nex E6000 6 kWh AC-coupled plug and play solar battery
No. It is a fixed home battery coupled on the AC side, with no photovoltaic input: it plugs into a socket, alongside a solar installation that is already tied to the grid. It is not a portable power station.
Samduo offers one to measure household consumption and aim at zero feed-in. It is not in the box of the battery alone (listed separately at £112 in the brand's UK shop), but some offers include it. Fitting it in the consumer unit is a job for an experienced technician.
No: the manual gives 800 W to the grid, the ceiling for plug and play systems, while charging reaches 2600 W. Samduo publishes grid connection certificates (EN 50549-1, VDE-AR-N 4105); the steps required depend on your country and your installation, so check them before installing.
A dedicated off-grid backup port feeds the appliances plugged straight into it, up to 2600 VA continuously and 3640 VA for 10 seconds: enough for a fridge, a router or lighting. Samduo does not state a switchover time in the documents we read.
Yes, with the supplied bracket, preferably on a brick or concrete wall; it can also stand on the floor. It weighs 59 kg and is 11.9 cm thick: plan for two people, 50 mm of clearance around it and an external earth connection, which the manual requires.
Today we find an active offer only in France and Germany. The brand's UK shop lists it at £1,723 but shows it as sold out, and we have found no offer in Italy, Spain or the United States.
