Hoymiles HMS-800W-2T (microinverter)

Available abroad

An 800W two-panel microinverter common in EU balcony kits.

AC output: 800W
Type: Microinverter system
Battery: Not included
UK availability: Not in UK

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

Sold in other markets (for example the EU), but not confirmed for UK plug-in use. 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. At least 44 compliant kits from other suppliers name a Hoymiles microinverter in their register entry. See the kits the register lists as compliant and the UK legal status.

Overview

The Hoymiles HMS-800W-2T is an 800VA microinverter with two independent MPPT inputs for two panels, common in EU plug-in / balcony solar kits. It accepts up to 65V DC input per channel and converts panel output to mains-compatible AC, with a built-in Wi-Fi module and rapid-shutdown compliance.

Hoymiles microinverters have a large global installed base. Plug-in use in the UK is not confirmed as compliant. The system is monitored via Hoymiles S-Miles (Direct Connection or S-Miles Cloud).

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.
