At a glance

  • We read the ENA Type Test Register on 30 September 2026. Two EcoFlow entries had changed from Non-compliant to Compliant: ECOFL/21606/V1/A1 and ECOFL/21128/V1/A3.
  • The register listed 84 plug-in solar kits as compliant, from 21 suppliers — up from 68 when we last checked on 22 September.
  • Solarfy and Worldwide Solar appear as compliant suppliers for the first time, and a Perlight kit also changed to Compliant.
  • “Non-compliant” on this register does not mean a kit failed a test. It means the ENA is waiting for information it needs to complete the assessment.
  • A listing covers one exact combination of inverter, panels and mounting. Match the model code on the seller’s page to the register entry before you buy.

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 30 September 2026, under its “Plug-in Solar” device type. It held 101 entries: 84 marked Compliant, from 21 suppliers, and 17 marked Non-compliant. Eight days earlier, on 22 September, it held 84 entries with 68 marked Compliant.

What changed for EcoFlow

Two entries from EcoFlow Inc. changed status from Non-compliant to Compliant:

  • ECOFL/21606/V1/A1 — listed as “EF-PS-800 + SPDG505-N108R12 Plug-In Solar Kit”, 0.8 kW.
  • ECOFL/21128/V1/A3 — listed as “EFStreamPlug-inSolarkit-UK-FlatRoof / EFStreamPlug-inSolarKit-UK-Facade / EFStreamPlug-inSolarKit-UK-PitchedRoof”, 0.8 kW.

Both are recorded as meeting G98. These are the register’s own model strings, quoted exactly: a register entry names a specific combination of inverter, panels and mounting, not a brand. We have not tested any of these kits, and this is a record of the register rather than a recommendation.

What else moved in eight days

  • Two new suppliers with compliant kits. Solarfy appears with the Solo 455 and Duo 910 (SOLAW/21640/V1 and SOLAW/21608/V1). Worldwide Solar appears with ten compliant combinations built around Hoymiles HMS-800-2WB or VaySunic VM800WE-P2 microinverters and JA Solar or AIKO panels.
  • Perlight. PERLI/21554/V1, the PowerPlug+ MAX 465, changed from Non-compliant to Compliant. Five further Perlight entries were added as Non-compliant.
  • A new VALE kit. VALEG/21271/V1/A1, the VALE Plug-In Solar 900Wp MX800lite 3-in-1 Mounting Kit.
  • Entries can disappear. Seven Non-compliant entries were removed altogether, six of them from Worldwide Solar, and one entry was amended to a new reference.

What “Non-compliant” actually means

It is easy to read the word as a failed test. On this register it means the ENA does not yet have everything it needs to complete the assessment, and a manufacturer can move an entry to Compliant by supplying it — which is exactly what happened here. That is also why we count Non-compliant entries on our register page but never name them: a status can change within days, and naming a product for a paperwork gap would be unfair and quickly out of date.

What it means for UK buyers

  • Check the exact model, not the brand. A listing covers one combination. The same microinverter sold with different panels, or with a different mounting system, is a separate entry and may not be listed.
  • Match the code on the seller’s page to the register. Retailers rarely print the register reference. Look for the model code in the specification and search the register for it.
  • Re-check close to the day you buy. The register gained 24 entries and lost seven in eight days. Our list is dated for that reason.
  • The other rules still apply whichever kit you choose: 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 those kits are actually sold, see where to buy plug-in solar kits.

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.
