Hoymiles plug-in solar

Hoymiles is a microinverter manufacturer; its HMS-800W-2T two-panel microinverter is common in EU balcony kits.

No Hoymiles plug-in solar kit listed as compliant on the ENA register

Hoymiles's plug-in / balcony products are sold in the EU and some are obtainable in the UK, but only the exact models listed as compliant on the ENA Type Test Register may be used for plug-in connection in Great Britain — see the UK legal status.

When we last checked the register, on 16 October 2026, it listed no plug-in solar kit from Hoymiles as compliant. At least 44 compliant kits from other suppliers name a Hoymiles microinverter in their register entry. See the kits the register lists as compliant.
