New ENA-Approved Plug-In Solar Kits: What's Just Landed on the Register

Every plug-in microgenerator kit sold legally in the UK has to use a micro-inverter that appears on the Energy Networks Association's G98 compliant device register — the master list DNOs and retailers check against to confirm a product actually meets the BSI product standard. We track that register and keep a live, auto-updated copy of it on this site, and the last few weeks have seen a genuine wave of new listings worth flagging if you're about to buy.

What's new on the register

Since late September, two manufacturers have added a cluster of new entries. Solarfy Ltd listed its Solo 455 plug-in kit (ref. SOLAW/21640/V1), a smaller 455W single-panel system aimed at tighter balconies and spaces where an 800W twin-panel rig simply won't fit — we cover how it stacks up against the market leader in our Solarfy Solo 455 vs EcoFlow STREAM comparison.

The bigger story is Worldwide Solar Ltd, which has pushed through a run of new "Plug & Play" kit combinations built around two micro-inverters already on the register — the VaySunic VM800WE-P2 and the Hoymiles HMS-800-2WB — paired with panels from JA Solar and AIKO. Within the space of about 48 hours, Worldwide Solar added variants combining each inverter with monofacial and bifacial JA Solar JAM54D40/D41 panels, and separately with AIKO Neostar monofacial panels, some bundled with a mounting system and some sold as inverter-plus-panels only, for buyers who already have brackets or a frame. We reviewed the flagship version of this kit in detail in our Worldwide Solar Plug & Play review.

What's notable here isn't a new piece of hardware — the VaySunic and Hoymiles inverters were already G98-compliant before these listings — it's that Worldwide Solar is now offering buyers far more choice in panel type (mono vs bifacial) and bundle (with or without mounting) around the same core inverter, which is exactly the kind of market maturation you'd expect a few months into a newly-legal product category.

Why this matters if you're buying

Every one of these listings carries g98GB: true on the register, meaning the inverter has passed the anti-islanding and grid-protection testing required under SI 2026 No. 848. That's the single most important thing to check before you buy any plug-in solar kit — not the brand name on the box, but whether the actual micro-inverter inside it has a corresponding entry on the ENA register. Our guide on how to spot a non-compliant kit walks through exactly how to cross-reference a product listing against the register before you buy, and it's worth five minutes of your time even for a kit sold by a major retailer.

More competition is good news for buyers

Having Solarfy and Worldwide Solar actively adding new SKUs alongside established names like EcoFlow, Anker and the Hoymiles/APsystems micro-inverter ecosystem is a healthy sign for the category. More choice on panel type, bundle configuration and price point means buyers can match a kit more precisely to their space and budget rather than accepting a one-size-fits-all package — our best plug-in solar kit roundup gets refreshed regularly as new options like these prove themselves, and our retailer availability tracker follows where each one actually ends up in stock.

It's also a reminder that the register itself is a living document, not a fixed list you check once. Inverters get superseded, firmware versions get added as separate entries, and new manufacturers enter the market every few weeks. If you're doing your own research before a purchase, always pull the current register rather than relying on a screenshot or a forum post from a few months ago — our live compliant device table is refreshed automatically whenever the ENA publishes an update, so it reflects exactly what's on the official list right now.

What to check before buying any new-to-market kit

New listings are a good sign, but a brand-new entrant also means less of a track record. Before buying from a manufacturer you haven't heard of:

• Confirm the inverter model number on the product page matches an entry on the live register, not just the brand name
• Check whether the kit includes a mounting system or not — several of the new Worldwide Solar listings are inverter-and-panels only, with brackets sold separately
• Look for UK-based after-sales support and a clear returns process — our consumer rights guide covers what you're entitled to if a kit arrives faulty
• Compare the price against an established alternative like EcoFlow's STREAM range before assuming "newer" means "cheaper" — it doesn't always

How do I know if a plug-in solar kit is actually G98-compliant?

Check the exact micro-inverter model named on the product listing against our live ENA compliant device table, which mirrors the official Energy Networks Association register. If the inverter model isn't listed with g98GB: true, the kit isn't legally compliant for use in Great Britain, regardless of what the marketing claims.

Are new manufacturers like Solarfy and Worldwide Solar as reliable as EcoFlow?

They use the same category of G98-certified micro-inverter hardware, so the core compliance and safety picture is equivalent. The main differences are track record, UK after-sales support and warranty handling — established names like EcoFlow currently have a longer history of UK customer service, while newer entrants are still building that reputation.

Does a kit need its own standalone ENA listing, or can it reuse an existing inverter's approval?

A full kit (inverter plus panels) is typically listed under its own reference number, but it inherits compliance from its micro-inverter's existing G98 approval — you'll often see the inverter's own ENA reference quoted inside the kit's listing comments, as with the VaySunic and Hoymiles units used in several of the new Worldwide Solar kits.
