Type: Microinverter system
Battery: Not included
UK availability: Available

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. See the kits the register lists as compliant and the UK legal status.

Overview

The Anker SOLIX RS40P is a plug-in / balcony solar system. Its microinverter ships limited to 600W and auto-upgrades to 800W AC (up to 799VA continuous) after network setup. The standard kit pairs it with two solar panels (around 820W in the 2 × 410W configuration; higher-output IBC panel variants are also offered).

It is sold in the EU and is obtainable in the UK; plug-in use is not confirmed as legal in the UK. The system is monitored through the Anker app, and Anker quotes a 25-year guarantee of 84.8% panel output.

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.
