ENA G98 Type Test Register: Which Plug-In Solar Kits Are Actually Certified

If you want a straight answer to "can I actually plug this in," there is exactly one place to look, and it is not a retailer's product page, not a brand's press release, and not a comparison table on a blog (including, to be blunt, parts of this one). It is the ENA G98 Type Test Register, run by the Energy Networks Association at connect-direct.energynetworks.org. Since Statutory Instrument SI 2026/848 came into force on 27 August 2026, that register — filtered to device type 14, "Plug-in Solar" — is the single legal source of truth for whether a specific plug-in solar microinverter model is lawful to connect to a UK socket today. Everything else, however well-intentioned, is downstream of it.

That distinction matters more than it sounds. A brand can genuinely believe its product is compliant, list it as "MCS-exempt" or "G98-ready" on Amazon, and still be wrong, or simply early, because the paperwork with the ENA hasn't cleared yet. The register is not a marketing claim. It is the actual pass/fail record. This article exists to explain how it works, what its current state is as of 26-28 August 2026, and — most importantly — how to check it yourself, because the one certainty about a register is that it changes and today's snapshot will not stay accurate forever.

For the wider legal picture around the new rule, see our explainer on whether plug-in solar panels are legal in the UK in 2026, and for a plain-English rundown of when you do and don't need an electrician involved, read do plug-in solar panels need an electrician.

What G98 is, and why it applies to plug-in solar microinverters

G98 is an existing Energy Networks Association engineering recommendation, not something invented for this new rule. It covers how small-scale generating equipment — up to 16A per phase, which comfortably covers the single microinverter used in a typical plug-in solar kit — is allowed to connect to the UK's distribution network without the generator owner having to go through prior individual notification to their district network operator (DNO) beyond the standard process. Before SI 2026/848, G98-compliant generating kit still generally needed an MCS-certified installer to fit it. What the new rule does is carve out a specific exception: a panel-plus-microinverter unit that plugs into an ordinary 13A wall socket can now be self-installed, with no electrician and no MCS certification required, provided — and this is the entire hinge of the new law — the exact microinverter model has passed G98 type-testing and is listed as "Compliant" on the register. The "type test" part is the key phrase. Manufacturers don't self-certify by writing "G98 compliant" on a spec sheet. They submit specific inverter models for formal testing against the G98 criteria and the government's Interim Product Specification, and the ENA records the result, model by model, on the public register. A brand can have some models compliant and others still in the queue. That's why the article title says "kits," not "brands" — compliance is granted per specific device, not per company.

What "Compliant" and "Non-compliant" actually mean on this register

This is the part that trips people up, so it's worth being precise. On the ENA G98 Type Test Register, "Compliant" means the specific microinverter model has completed formal type-testing against the Interim Product Specification (version 2) and the G98 criteria, and uses an approved plug arrangement. Once a device carries that status, it is lawful to self-install as a plug-in solar unit under SI 2026/848. "Non-compliant," on the same register, does not mean the product failed a safety test, was recalled, or is banned. As of the most recent check in late August 2026, it generally means the manufacturer's testing and paperwork with the ENA simply hasn't finished yet. It's a status of "not yet cleared," not "rejected." Plenty of Non-compliant entries on the register today may well become Compliant in the coming weeks once their type-test evidence is verified and the ENA updates the entry — there's no fixed public timetable for that, it happens per-manufacturer as their testing completes. But — and this is the operative legal point, not a technicality — the practical effect of the two statuses is currently identical for a would-be buyer: if a device is listed Non-compliant, it is not currently lawful to plug that specific unit into a UK socket under this scheme, however good the hardware is and however close the manufacturer might be to finishing their paperwork. "Nearly compliant" and "compliant" are not the same thing in front of a DNO or an insurer. Don't let good marketing blur that line for you.

The state of the register, 26-28 August 2026

As best documented at the time of writing, entries on the G98 Type Test Register under device type 14 existed for products from UKSOL, EcoFlow, Anker, TSUNESS, FoxESS, Octopus Energy (who filed a FoxESS-based microinverter), Segen, Modular Solar, and Perlight. Of all of those, UKSOL Ltd's 7 kits were the first to reach "Compliant" status — the first plug-in solar entries on the entire register to clear the bar. Shortly after, the Perlight PowerPlug MAX 465 was added as Compliant too, bringing the running total to 8 compliant devices as of the most recent check. Every other named brand's entry — EcoFlow, Anker, TSUNESS, FoxESS, the Octopus-filed FoxESS unit, Segen, and Modular Solar — was listed Non-compliant at last check. If you've independently confirmed a UKSOL device's compliant status on the live register yourself (don't just take our word for the snapshot above — it can and will move), the two most commonly bought UKSOL kits worth a look are the UKSOL Pro Max 1260W on Amazon · on eBay, and the smaller UKSOL Pro Plus 1030W on Amazon · on eBay. We cover the full UKSOL range, including how the individual 7 kits differ, in our dedicated UKSOL plug-in solar kits compared article, and how they stack up against the rest of the market in our best plug-in solar kits UK 2026 roundup. Worth flagging explicitly: EcoFlow's plug-in solar kit on Amazon · on eBay and Anker's plug-in solar kit on Amazon · on eBay are both widely available to buy right now, and neither is doing anything wrong by selling the hardware. But as of this check, neither is listed Compliant on the G98 register, which means self-installing either one as a plug-in-and-go device is not currently lawful under SI 2026/848, whatever the box or listing implies. That could change — remember, Non-compliant is usually a "not yet finished," not a "failed" — but until an entry actually flips to Compliant on the live register, treat it as not cleared.

The register itself is the primary source, but it is a technical database rather than a shopping list. The 800wsolar ledger maintains a dated, plain-English mirror of the same position — certified kits in one table, kits awaiting certification filed separately — and records when each entry was last checked.

How to check the register yourself, step by step

This is the single most useful thing you can do before buying anything described as "plug-in solar," and it takes under two minutes:

1. Go to connect-direct.energynetworks.org, the ENA's Connect Direct portal.
2. Find the G98 Type Test Register (sometimes surfaced as a searchable database or downloadable list, depending on how the portal is laid out on the day you visit).
3. Filter or search by device type — you want device type 14, "Plug-in Solar", specifically, since G98 covers other generating equipment types too and you don't want to accidentally read across from an unrelated category.
4. Search for the exact model name and, ideally, model/reference number printed on the box or listing — not just the brand name, since compliance is per-model.
5. Check the status column reads "Compliant," not "Non-compliant," "pending," or absent altogether (absence usually just means it hasn't been submitted for testing at all).
6. Screenshot or note the date you checked, since — as this whole article keeps stressing — the register is a live document and today's answer might not be tomorrow's.

Do this before you buy, and ideally again right before you install, since there can be a gap of weeks between ordering a kit and getting round to plugging it in. Don't rely on a retailer's product description, a "G98 ready" badge on packaging, or a review site's older snapshot (including this one) as a substitute for the live check. Marketing copy is written to sell a product this month; the register is updated whenever the ENA verifies new evidence, on its own schedule.

If you would rather not work through the register interface for every kit you are considering, the 800wsolar certified-kit table maps each ENA-listed device back to the product name and price you will actually see at a retailer.

What happens after the register check: registration and your DNO duty

Confirming a device is Compliant on the register is necessary but not sufficient — it's step one of two. Separately, and regardless of which compliant kit you've bought, UK law requires every plug-in solar device to be registered at myplugin.solar once it's connected, and the owner must notify their district network operator (DNO) within 28 days of connecting it. This is a different administrative step from the G98 register check — the G98 register tells you whether the hardware is lawful to use at all; the myplugin.solar registration and DNO notification are what make your specific installation compliant with the ongoing network-safety process, the same underlying logic G98 has always existed to serve (letting DNOs know what small-scale generation is on their network without requiring a full grid application for every kettle-sized inverter). Skipping this step isn't a paperwork technicality either — DNOs use aggregate registration data to manage local network loading, and it is a condition of the new interim rules, not an optional extra.

Why the register — not price, brand, or panel wattage — is the actual buying decision

It's tempting to shop for plug-in solar the way you'd shop for any other electronics: compare panel wattage, battery capacity, price per watt, brand reputation, review scores. All of that is worth doing eventually, and we cover it in detail in our best plug-in solar kits UK 2026 roundup and our broader look at plug-in solar panels UK. But none of it matters if the specific model you're eyeing isn't on the Compliant list, because then the comparison is moot — you legally can't self-install it as plug-in solar yet, no matter how good its spec sheet looks next to a UKSOL unit. That's the uncomfortable truth this register exposes: in August 2026, "biggest brand" and "best reviewed" and "actually lawful to plug in today" are three completely different questions, and only one of the three brands with entries on the register so far — UKSOL, plus now Perlight for one model — can currently answer yes to all three. EcoFlow and Anker are both large, well-reviewed, broadly trusted consumer electronics brands, and both have hardware for sale that may well become fully compliant plug-in solar kits in the coming weeks or months. That's simply not the same as being compliant today. If you buy on brand reputation alone and skip the register check, you could end up owning perfectly good solar hardware that you're not currently allowed to self-install under the plug-in exemption — potentially needing to fall back on a full MCS-certified installation route instead, which is a different cost and hassle profile than the whole point of "plug-in solar" was meant to solve. For the full rundown of what the legal exemption does and doesn't cover, see plug-in solar panels legal UK 2026. The register is, in effect, the buying filter that should run before every other comparison criterion. Check it, then compare wattage and price among whatever passes.
