Hoymiles HiFlow Pro HMS-800-2WB with UK plug

The UK version of an 800 W Hoymiles microinverter: two MPPTs, Wi-Fi and Bluetooth, and a 5 m AC cable with a UK plug. The catch is the ENA plug-in register: we couldn’t confirm it’s listed, and a secondary source says the HMS series wasn’t in late 2026.

Cons

According to balconysolarguide.co.uk, Hoymiles had no ENA plug-in register entry for the HMS series in late 2026.
It’s the inverter only, while UK rules call for a complete product under IPS v2.
Panels and mounting are extra.

What it is

An 800 W microinverter with two MPPTs, Wi-Fi, Bluetooth and IP67 protection (part number HF-800-PRO). Unlike the continental version, it comes with a 5 m AC cable fitted with a UK plug.

UK rules

Plug-in solar has been legal in the UK since 27 August 2026 (SI 2026/848). The limits: no more than 800 W AC output and 2,000 W DC, a complete product under IPS v2, a BS 1363 plug with a fuse of 5 A or less, one unit per household (G98) and registration with the ENA (myplugin.solar).

According to balconysolarguide.co.uk (a secondary source), Hoymiles had no ENA register entry as plug-in for the HMS series in late 2026. Check this before using it via the plug route, and ask the seller whether it’s sold or certified as part of a complete system.

Other markets

With a UK plug it doesn’t suit Spain, Germany, France or Poland. There, look at the HMS-800W-2T or another continental inverter.

Check that the inverter is listed for G98 and tell your network operator (DNO). We have not yet confirmed that this kit meets version 2 of the government’s plug-in specification. Rules in the UK
