Certified Plug-In Solar Kits UK: Live Tracker

Which plug-in solar kits are certified against the UK Plug-in Solar Device Interim Product Specification v2 and legal to connect via a standard socket, now that SI 2026/848 is in force. We check the ENA register, manufacturer, retailer and GOV.UK sources and update this page weekly.

Last updated:

Current status: the law is in force, but no kit has completed UK Interim Product Specification v2 certification yet. Three microinverters (Anker, GoodWe, InstaGroup) are registered on the ENA Type Test Register under the plug-in solar category — all three are currently assessed non-compliant. Several other products are on sale in the UK but aren’t on the register at all. Being on sale, and even being registered, is not the same as being certified for standard-socket connection.

Kit certification tracker

KitOutputPriceStatus
Anker SOLIX AE1032Z1-20
First plug-in solar entry from a major balcony brand, registered 3 Aug 2026 as ANKER/20920/V1. ENA's engineers have assessed it non-compliant, so network operators are unlikely to accept it as-is.
0.8kWTBCRegistered — assessed non-compliant
GoodWe GW2K/GW3K-EMA-UK-G10
First manufacturer onto the plug-in solar register (29 Jul 2026), amended 11 Aug 2026. Still assessed non-compliant. Model name says 3kW but the default plug-in output is 0.8kW — raising it needs an authorised installer.
0.8kWTBCRegistered — assessed non-compliant
InstaGroup HF-800-WB microinverter
Registered 7 Aug 2026 — the only entry so far from a UK-based manufacturer. Assessed non-compliant; no UK consumer availability or pricing announced.
0.8kWTBCRegistered — assessed non-compliant
EcoFlow STREAM 800W
First UK government partner product; on Amazon UK. Not on the plug-in solar register — and its battery-equipped configurations fall outside the interim spec entirely.
800W~£499On sale, not yet certified
Hoymiles Balcony 800
Microinverter kits sold via UK resellers. Not on the plug-in solar register.
800W~£350–£450On sale, not yet certified
City Plumbing Plug-in 465W kit
Cheapest confirmed UK setup. Below 800W cap; not on the plug-in solar register.
465W£260On sale, not yet certified
Lidl / Amazon / Asda / B&Q / Currys / Screwfix / Wickes Own-brand kit
DESNZ's seven named retail partners. None has confirmed a product, price, or launch date.
~800W~£400–£600 (est.)Status unknown

Prices and status change frequently. Verify against the manufacturer and retailer before purchase; this tracker is informational and not legal advice.

What a kit must meet to qualify

Under SI 2026/848, a “plug-in microgenerator” must satisfy all of the following:

  • Generates electricity only from sunlight (solar)
  • Maximum AC output of 800VA (3.5A) and 2,000W of panels
  • Connects via a factory-fitted, non-rewireable BS 1363 plug with a fuse of 5A or less
  • Assessed and identified as compliant on the ENA Type Test Register — registration alone is not enough
  • Carries the compliance declaration and QR code on the product label
  • Batteryless (no importing electricity to store for later use)
  • Complies with the Plug-in Solar Device Interim Product Specification v2 (16 July 2026)

Work out your numbers before launch day

No kit is certified yet, so there’s nothing to time against a launch day. In the meantime, our free calculator estimates what an 800W kit would generate at your postcode, and the Sun Hours app gives you Sol’s 7-day forecast the moment your panels are up — setup takes two questions.

FAQ

Which plug-in solar kits are certified in the UK?

None, as of 29 August 2026. Three microinverters — from Anker, GoodWe, and InstaGroup — have been registered on the ENA Type Test Register under the plug-in solar device category, but all three are currently assessed non-compliant. SI 2026/848 is now in force, so the legal route is open; it's waiting on a product. This page is updated weekly.

Is a kit that's on sale automatically legal to plug in?

No. Being on sale in the UK is not the same as being certified for standard-socket connection, and being registered on the ENA database isn't automatically the same as being assessed compliant either — as the Anker and GoodWe entries show. Only a kit assessed compliant against the Interim Product Specification v2 is covered by SI 2026/848.

What happened on 27 August 2026?

The PSSR amendment (SI 2026/848) came into force as planned. From that date a certified kit can legally connect through a standard socket, one per household (not per circuit — that relaxation needs a separate G98 amendment with no date set), with the owner notifying their electricity distributor. No kit has cleared certification yet.
