Not listed as compliant for plug-in use on the ENA register

Obtainable in the UK, but not confirmed as legal or suitable for plug-in connection here. Plug-in solar is legal to use in Great Britain, but only kits listed as compliant on the ENA Type Test Register may be used — and this model was not listed as compliant for plug-in use when we last checked the register. We last checked on 16 October 2026, under the register’s “Plug-in Solar” device type. The register does list 2 plug-in solar kits from EcoFlow as compliant, under other model names. See the kits the register lists as compliant and the UK legal status.

Overview

EcoFlow PowerStream is a microinverter-based plug-in (“balcony”) solar system. It has two solar inputs (up to 400W each, 800W total) and converts panel output to mains-compatible electricity. EcoFlow ships it as a 600W unit that can be upgraded to 800W AC output for free where regulations allow.

It is sold in the EU and is also obtainable in the UK as a power product. It carries an IP67 weatherproof rating and can be paired with EcoFlow portable batteries, though no battery is required for solar generation. Plug-in use in the UK is not confirmed as compliant.

  • Configurable 600W or 800W AC output
  • Two solar inputs (up to 400W each)
  • IP67 weatherproof rating
  • Works with EcoFlow portable batteries (optional)
  • Monitored via the EcoFlow app (Wi-Fi & Bluetooth)

Reviews & testing

We don't publish user reviews, and we haven't hands-on tested this system. This model was not listed as compliant for plug-in use when we last checked the ENA Type Test Register, so we can't responsibly review it for UK plug-in use. We won't invent ratings.

For the kits the register does list as compliant, see our ENA register list. In the meantime, check the manufacturer's documentation and reputable independent reviewers, and see our editorial policy.
