- Inverter: 3000 W built-in, pure sine, grid or off-grid
- Solar: 5000 W input, 4 MPPTs
- Durability: IP65, 10,000 cycles, 10-year warranty
- Built-in inverter, works alone with no existing setup
Detailed overview: EcoFlow Stream 5000
The EcoFlow Stream 5000 is the fully self-contained version of the new STREAM range: unlike the Stream AC 5000, which simply stores energy produced by an existing solar inverter, this model carries its own 3000 W bidirectional inverter. As a result, it stands entirely on its own, with no existing solar setup required, handling generation, storage and output all at once.
Base capacity reaches 5024 Wh in LFP (LiFePO4) cells, rated for 10,000 cycles and backed by a 10-year warranty, two figures clearly aimed at daily long-term use rather than occasional backup. On the solar side, the unit accepts up to 5000 W of input across 4 independent MPPTs, enough to connect several strings of panels facing different directions without losing efficiency. On the output side, it switches between grid export and off-grid operation depending on the household's needs.
The most useful everyday feature is its UPS backup mode: during an outage, the switchover is claimed to be near-instant, avoiding any restart of sensitive devices such as the home router. On the expansion side, each tower accepts up to two additional batteries to reach 15 kWh, and up to six towers can be networked together for a total of 90 kWh, scalability designed to grow with a household's needs over several years rather than forcing a full system replacement.
The whole unit is IP65-rated, allowing outdoor installation near the meter or in a garage, at a claimed weight of 45.4 kg. Control runs through the EcoFlow app over WiFi and Bluetooth, with a local mode to keep operating without an internet connection. Launched in late August 2026, the Stream 5000 is currently genuinely available to order only in the UK; its rollout in France, Germany, Italy and Spain is announced for September 2026, with pricing already published by EcoFlow but no firm order possible yet. This listing will be updated as soon as sales actually open in those markets.

⚡ How long will this power station run a device?
With 5,024 Wh, the EcoFlow Stream 5000 external battery runs a fridge (50 W) for ~85h or an LED TV (90 W) for ~47h.
| Home | Runtime |
|---|---|
| Freezer (60 W) | ~71h |
| American fridge (150 W) | ~28h |
| Espresso machine (1300 W) | ~3h15 |
| Space heater (1500 W) | ~2h50 |
| Outdoor & workshop | Runtime |
|---|---|
| Wi-Fi router (15 W) | ~285h |
| CPAP machine (40 W) | ~107h |
| Water pump (60 W) | ~71h |
| Games console (200 W) | ~21h |
Rough estimate: real consumption varies, and very power-hungry appliances (heating elements) must stay below the output power.
What is this power station best for?
-
Home & Power cuts Ideal
The Stream 5000 is built to act as a genuine home battery: with its built-in inverter and a near-instant UPS switchover (a claimed 0 ms), it takes over the instant the mains cuts out, without restarting sensitive devices like the home router. Its base 5024 Wh already covers a good share of a household's essential needs during an outage, and its networked design lets you stack up to two expansion batteries per tower (15 kWh), then link up to six towers to reach 90 kWh in total, enough to aim for several days of autonomy as needs grow. Its IP65 rating allows outdoor installation, near the meter or in a garage, freeing up indoor space.
-
Off-grid & Solar Ideal
With 5000 W of solar input spread across 4 MPPTs, the Stream 5000 easily absorbs several strings of panels, and its built-in 3000 W inverter lets it run entirely on its own, with no existing solar inverter required (unlike the Stream AC 5000). It switches between grid export and off-grid output as needed, and its capacity, expandable up to 90 kWh, aims at serious residential solar storage rather than a top-up battery. Its claimed 10,000 cycles and 10-year warranty give real visibility on the payback of a system built to live with the house, not just the seasons.
-
Remote work Suitable
Installed once and for all near the consumer unit, the Stream 5000 protects a home workstation from micro-outages via its UPS mode, without any day-to-day thought required. Its 5024 Wh (expandable) comfortably cover a computer, monitors, router and desk lighting over a long stretch, well beyond a typical UPS. It is not a portable solution to carry room to room (45.4 kg, fixed format), but for a desk that always stays in the same place, it is the kind of safety net you forget about, until the day it matters.
-
Health & CPAP Suitable
For a CPAP machine used every night at home, the Stream 5000 offers background security rather than a travel solution: its UPS mode takes over during a night-time outage without interrupting treatment, and its base 5024 Wh represents ample reserve for many nights, even without the expansion pack. Its ability to grow up to 90 kWh networked means other medical equipment can comfortably join the same circuit later. Its weight and fixed format do, however, keep it to home use rather than a travel bag.

Comparison
At close to £1600, the EcoFlow Stream 5000 naturally compares to its own sibling, the Stream AC 5000, as well as two other plug-and-play home batteries in the same range, searched for via queries like "Stream 5000 vs Stream AC 5000" or "Stream 5000 vs Solarbank 4": the Anker Solix Solarbank 4 E5000 Pro, which shares the exact same base capacity, and the larger, pricier Zendure SolarFlow 4000 Mix AC+.
| Criterion | EcoFlow Stream 5000 | EcoFlow Stream AC 5000 | Anker Solix Solarbank 4 E5000 Pro | Zendure SolarFlow 4000 Mix AC+ |
|---|---|---|---|---|
| Capacity | 5024 Wh (LFP) | 5024 Wh (LFP) | 5024 Wh (LFP) | 8000 Wh (LFP) |
| Built-in inverter | Yes, 3000 W | No, adds onto an existing inverter | Yes, PluginPower 2.0 | Yes, 4000 W bidirectional |
| Solar input | 5000 W, 4 MPPTs | Not specified (depends on the existing inverter) | 5000 W, 4 MPPTs | 5000 W in PV bypass |
| Off-grid output | 3000 W | None (requires an existing inverter) | 2500 W | 3680 W |
| Expandable up to | 90 kWh | 90 kWh | 30 kWh | 50 kWh |
| Observed price | £1599 | £1499 | ≈ £1624 | ≈ £2051 |
In short, the EcoFlow Stream 5000 stands apart from its own AC 5000 sibling mainly through its built-in inverter, which lets it run with no existing solar setup at all, a real advantage for anyone starting from scratch. Against the Anker Solix Solarbank 4 E5000 Pro, capacity and price are nearly identical, but the Stream 5000 keeps a higher off-grid output and a much higher expansion ceiling (90 kWh versus 30 kWh). The Zendure SolarFlow 4000 Mix AC+ offers more raw capacity and output power, but at a noticeably higher price.
