How long has each compliant kit been on the register?
Last verified: 24 September 2026 at 23:07 — read from the ENA type test register by us.
Why this page exists
A live list can tell you what is there today. Only a kept log can tell you how long it has been there. We have kept an append-only log since 5 August 2026 — 13 timestamped readings, of which 10 record every device individually. The counts below are measured from that log, not estimated.
Every number on this page is measured per manufacturer from its own first appearance, not from the start of the log. A manufacturer first seen on 24 September 2026 cannot have been present for ten readings.

“Same set of models for” counts backwards from 24 September 2026: the number of consecutive readings in which that manufacturer’s exact set of compliant references did not change. UKSOL Ltd shows ten readings but nine unchanged because it went from four compliant models to seven on 26 August.
The list moves more than you would think
- Perlight replaced its entire first batch, then grew. Four Perlight references (PERLI/21112/V1, PERLI/21113/V1, PERLI/21114/V1 and PERLI/21116/V1) were in the list and gone by our reading of 27 August 2026. Twelve of the thirteen Perlight models listed compliant today carried over from our 16 September 2026 reading, and one, PERLI/21554/V1, is new; the manufacturer that grew most this time is Zendure, from no entries to six compliant models.
- Entries come back under a new revision — and leave again. City Plumbing’s kit appeared as CITYP/21096/V1/A3, left, and is on the list today as CITYP/21096/V1/A4. InstaGroup’s INS-PPG-800 has been through A2, A8 and A9 in our log. Anker’s ANKER/20920/V1 became ANKER/20920/V1/A2 on 31 August — and that reference left too, on 9 September. EcoFlow lost ECOFL/21128/V1 on 9 September and was back on 16 September 2026 as ECOFL/21128/V1/A1, still “Non-compliant”; by 24 September 2026 that reference had gone too, and ECOFL/21128/V1/A3 was listed, marked “Compliant”. A reference disappearing is not always a product disappearing.
- One manufacturer that had gone came back, and six are new to the register entirely. TSUNESS had no entry at all in our 16 September 2026 reading and has three again on 24 September 2026. Separately, Longshen, Plugsol, The Solar Home, VALE, Voltacon and Zendure appear in our log for the first time on 24 September 2026.
- Four manufacturers have entries in our log and none on the register today: Anker, FoxESS, GoodWe, Worldwide Solar.
- Being on the register is not the same as being compliant on it. Longshen, Plugsol, Sigenergy, The Solar Home and Voltacon have entries in our 24 September 2026 reading, but every one of them is marked “Non-compliant”, so none appears in the table above. InstaGroup appears on both sides: it has compliant references and a non-compliant one.

What this page does not mean
A device leaving the list is not evidence that it is a poor product. Entries move for reasons we cannot see from the outside: a revision, a withdrawal, an administrative change, a resubmission. We record what changed and when we saw it; we do not guess at reasons.
A long run on the list is not a recommendation either. It tells you the entry has been stable. It says nothing about how the kit performs, what it costs, or whether it suits your wall.
Compliant here is the register’s own assessment, that network operators will accept the equipment. It is not the same thing as certification to the Interim Product Specification v2, and we have not verified that any of these kits carries that certification.
We have not tested any of these products. This page counts entries in a public register; it is not a review.
