Solen Energy joins the register, Sigenergy out

Two more compliant kits, two suppliers gone, and a Hoymiles microinverter turning up inside yet another brand’s kit. The weekly churn at the edges of the register continues.

At a glance

  • We read the register on 16 October 2026: 134 entries, 122 Compliant from 27 suppliers, 12 Non-compliant. On 10 October it was 133 entries, 120 Compliant from 26.
  • Solen Energy UK has its first Compliant entry — a kit pairing a Hoymiles HMS-800-2WB microinverter with two Longi panels.
  • Jiangsu VDS added a second Compliant kit, this one with two 630W panels.
  • Sigenergy’s two Non-compliant entries and The Solar Home’s have been removed entirely.
  • Two new Non-compliant entries arrived, from Huiyuanfang and VaySunic.

We read the ENA Type Test Register on 16 October 2026. It held 134 entries: 122 marked Compliant from 27 suppliers, and 12 Non-compliant. On 10 October it was 133 entries, 120 Compliant from 26 suppliers.

Two new compliant kits

  • Solen Energy UK, its first entry: SOLEO/21743/V1/A2, “Solen Energy UK Plug in Solar Kit - HMS-800-2WB 800W microinverter + 2 x Compatible Longi LR7-54HVB”, 0.8 kW. It appeared as Non-compliant on 5 October, vanished from the register by 10 October, and is now back as Compliant with an /A2 reference.
  • Jiangsu VDS, a second entry: JIANM/21819/V1, “VDS power 800W balcony/wall/ground plug in solar kit - 2pcs 630W”.

The Solen entry is worth a second look. Its register note carries a G98 reference beginning HOYMZ, and the kit is built around a Hoymiles HMS-800-2WB microinverter paired with another maker’s panels. That pattern — one widely used microinverter inside many suppliers’ kits — is now the norm rather than the exception: by our count 44 compliant kits from other suppliers name a Hoymiles microinverter in their register entry. See what the register says about Hoymiles.

Three entries removed

  • SIGEN/21402/V1 — Sigenergy, “Sigen Plug-in PV 400”
  • SIGEN/21404/V1 — Sigenergy, “Sigen Plug-in PV 800”
  • THESP/21507/V1/A1 — The Solar Home, “LS-800Mi”

All three were Non-compliant when we last saw them, and Sigenergy now has no entry on the register at all. Two new Non-compliant entries arrived in the same period, from Huiyuanfang (“XDS-PIS-920-800”) and VaySunic (“VaySunic 800W UK Plug-in Solar Kit_PV 910W”).

What it means for UK buyers

  • Entries move in both directions, and they come back. The Solen kit was Non-compliant, then gone, then Compliant, in eleven days. A status you saw last week tells you nothing about today.
  • The brand on the box is not the inverter inside. If a kit names an HMS or HiFlow model, that is a Hoymiles microinverter in someone else’s kit — which is fine, and is how most compliant kits are built.
  • A withdrawn entry is not a verdict. We do not know why Sigenergy’s entries went, and we are not going to guess.
  • Check the exact reference on the day you buy. Our dated list is at kits on the ENA register.

Where the UK rules stand

Plug-in solar has been legal to use in Great Britain since 27 August 2026, when SI 2026/848 came into force alongside Ofgem-approved changes to the G98 connection code — provided the kit is listed as compliant on the ENA Type Test Register. Northern Ireland is not covered. See the current legal status and our editorial policy.
