From ESS News
China-based storage system manufacturer Ecoflow has been teasing an update to its Stream series of products and has now launched the products in the UK, with the Stream 5000 and Stream AC 5000 now available for pre-order.
While the company is launching in Europe and confirmed this to ESS News at Intersolar 2026, the launch in the UK highlights its expanding portfolio ahead of country-specific launches in Europe.
Previous Stream models such as the Stream Ultra remain on sale, but the expanded portfolio in the UK now includes 5 kWh batteries with both the Stream 5000 and Stream AC 5000, along with a 5 kWh expansion battery option as well. When paired with solar generation or expansion batteries, the Stream 5000 can deliver up to 3 kW of output power according to EcoFlow.
The EcoFlow Stream 5000 has a maximum charging power of 4 kW, maximum discharging power of 3 kW. The main unit battery for this modular system has charging and discharging power of 2.5 kW. EcoFlow Stream 5000 is rated for a 3 kW AC charging input. EcoFlow Stream 5000 are equipped with four maximum power point trackers (MPPT) and take a PV input power of 5 kW (across four 1.25 kW inputs) at a maximum PV input voltage of 60 V.
For AC output, this varies between off-grid and grid tied, with off grid rated at 3 kW and grid-tied AC output listed as 800 W/3 kW on the product specification sheet. The Stream 5000 has a net weight of 45.4 kg, dimensions 295 mm x 489 mm x 298 mm, and carries a 10-year warranty.
EcoFlow Stream 5000
EcoFlow Stream AC 5000 has nearly identical specifications but the main difference is that it doesn’t offer an inverter for charging from solar PV. It has a maximum charging power of 3 kW rather than 4 kW, and a slightly lower weight at 44.6 kg.
The EcoFlow Stream 5000 and EcoFlow Stream AC 5000 each offer a lifespan of 10,000 cycles.
All products in the EcoFlow 5000 range are equipped with low-temperature charging activation at below 10 C, have an IP65 ingress protection rating and a maximum 30 dB noise specification, according to the manufacturer.
EcoFlow highlighted that the new Stream 5000 series offers is able to work with its last generation of Stream products to host an expanded capacity of up to 90 kWh.
It also offers a “local” mode, for operation without cloud control. The company also noted two pressure relief valves in the latest models; the safety mechanisms designed to manage off-gassing that occurs during thermal runaway.
Pricing and availability of the EcoFlow Stream 5000 and Stream 5000 AC UK
Introductory or early-bird pricing for the EcoFlow Stream 5000 is £1599, while the Stream AC 5000 is £1499. Early bird pricing is available until October 7.
On the EcoFlow UK website, an offer describes paying £9.90 to lock in a launch offer to save £100.
EU to come
EcoFlow has confirmed on multiple occasions a wider EU rollout of the new Stream series and the 5000 models. Currently, they are listed on EU sites including EcoFlow’s German website, where the products are listed with an associated registration for possible purchase. The Stream 5000 starts at €1,299 in Germany (which is VAT-free).
