ENA register passes 100 compliant plug-in kits

We read the ENA Type Test Register on 5 October 2026: 115 plug-in solar kits marked Compliant, from 25 suppliers, up from 84 and 21 five days earlier. More choice, and more reason to check the exact model.

At a glance

  • We read the register on 5 October 2026. It held 135 plug-in solar entries: 115 marked Compliant from 25 suppliers, and 20 marked Non-compliant.
  • On 30 September it held 101 entries, 84 Compliant from 21 suppliers. Nothing was removed; the growth is new entries plus five status changes.
  • Clean My Carbon, VDS and Voltacon have a compliant entry for the first time, and Fusion Renewables gained its first.
  • Five Perlight PowerPlug+ kits moved from Non-compliant to Compliant. Worldwide Solar now holds 31 compliant combinations on its own.
  • Twenty entries are still Non-compliant, including four new Thunder Energy “Thunder Bolt” records, so matching the exact model matters more, not less.

Only kits listed as compliant on the ENA Type Test Register may be used for plug-in solar in Great Britain. We read the register ourselves on 5 October 2026, under its “Plug-in Solar” device type. It held 135 entries: 115 marked Compliant, from 25 suppliers, and 20 marked Non-compliant.

Five days earlier, on 30 September, the same device type held 101 entries with 84 Compliant from 21 suppliers. Nothing was removed in between. The register has grown by about a third in under a week.

Who is new

Three suppliers hold a compliant plug-in entry for the first time, and one that previously held only Non-compliant records gained a compliant one. The references and the register’s own model strings, quoted exactly:

  • Clean My Carbon — CLEAN/21510/V1/A4, “Clean 800w”, 0.8 kW.
  • VDS (Jiangsu VDS Renewable Technology) — JIANM/21620/V1/A1, “VDS power 800W balcony/wall/ground plug in solar kit”, 0.8 kW.
  • Voltacon — VOLTD/21572/V1/A2, “HF-800-WB”, 0.8 kW.
  • Fusion Renewables, its first compliant entry — FUSIO/21737/V1, “FPNP/HMS-800-2WB/EUR475X2”, 0.8 kW.

Segen also added SEGEN/21723/V1/A1, “PIS-FE-SO-66H-940”.

What moved

  • Perlight. Five PowerPlug+ kits changed from Non-compliant to Compliant: PERLI/21643/V1/A2, PERLI/21644/V1/A2, PERLI/21645/V1/A2, PERLI/21646/V1/A3 and PERLI/21647/V1/A2. Perlight now holds 18 compliant entries.
  • Worldwide Solar. Twenty-one new compliant combinations, taking it to 31 — by far the most of any supplier. They pair a Hoymiles HMS-800-2WB or a VaySunic VM800WE-P2 microinverter with AIKO or JA Solar panels, each listed with and without a mounting system.

The catch: a listing is one exact combination

A bigger register is good news, but it makes the model check more important rather than less. Three things to hold on to:

  • The entry is the kit, not the brand. Worldwide Solar’s 31 entries are 31 separate combinations, and the register distinguishes “+ Mounting System” from “Mounting system not included”. The same inverter with different panels is a different entry.
  • A supplier can hold both statuses at once. Fusion Renewables has one compliant entry and two Non-compliant ones. Voltacon has one compliant and two Non-compliant. Thunder Energy has two compliant kits and four new Non-compliant “Thunder Bolt” records. The brand name tells you nothing on its own.
  • Non-compliant is not a failed test. On this register it means the ENA does not yet have everything it needs to finish the assessment — which is exactly what those five Perlight kits show, having moved to Compliant within days.

What it means for UK buyers

  • Match the model code, then the mounting. Find the code in the seller’s specification and search the register for it. If the kit includes a frame, check the entry covers the mounted version.
  • Re-check close to the day you order. Thirty-four entries appeared in five days. Our list is dated for that reason.
  • The other rules are unchanged: one plug-in device per household, up to 800 VA, no battery storage, and you must notify your network operator. Northern Ireland is not covered.

Every kit the register marks Compliant, by brand with its reference and the date we checked, is on our ENA register list. For where kits are actually on sale, see where to buy plug-in solar kits.

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.
