Plug-In Solar Brands in the UK: What Each One Sells

Several brands now sell solar in the UK, and not all of it is plug-in solar. This page lists what each brand sells here, whether it has an entry on the ENA plug-in solar register, the price we read and the catch to know about. We compare published pages and the public register. We have not tested any kit. Everything below was read on 9 November 2026.

The Short Version

• Octopus Energy and Thunder Energy sell battery-free kits that the ENA register lists as compliant, with prices we read on their own stores.
• EcoFlow’s STREAM microinverter is on the register, but EcoFlow’s own UK FAQ says an electrician must connect it to the distribution board.- Zendure has compliant entries for the SolarFlow 800, but its UK store only sells larger battery systems.
• We found no Plug-in Solar entry for Anker, Jackery or Renogy.

What Counts as Plug-In Solar Here

The rules decide what can sit in a comparison like this. A plug-in device is a solar generator of no more than 800 W AC that connects through an ordinary plug and socket, with no battery. SI 2026/848 reg. 2(3) It must also meet the DESNZ interim product specification, version 2. DESNZ interim product specification v2, 2026

So a brand can sell a great product that still does not fit. A system with a battery, or one rated well above 800 W, is a different product from a plug-in kit. The full rules are in our plug in solar UK guide.

How We Read the ENA Register

The Energy Networks Association keeps a public device register for plug-in solar. ENA Connect Direct, type Plug-in Solar, 2026 On 9 November 2026 it held 152 entries, 119 of them marked Compliant. We counted entries per manufacturer. A register entry shows that a device was assessed. It does not show that the brand sells it in the UK today, so we check each store separately.

Octopus Energy

Octopus sells two battery-free bundles on its own store: a single-panel bundle at £450 and a two-panel bundle at £650. Both use JA Solar 460 W panels, a microinverter and a 5 m cable with a three-pin plug. The two-panel price includes VAT and kerbside delivery. The ENA register has one compliant Octopus entry.

The catch is on payment for export. Octopus says export payments are only for Octopus electricity customers with a smart meter who bought the kit from Octopus, and only after DNO approval. Octopus also says that under permitted development you cannot install on fences, gates, walls, balconies or enclosures made of timber. Delivery for orders placed on 9 November was quoted as the end of November. Octopus lists compact kits and plug-in batteries as “Spring 2027”.

Thunder Energy

Thunder sells the Bolt range: the Bolt 460W at £549.99 and the Bolt 920W at £749.99, both with free UK delivery. The 920W has two 460 W panels and an 800 VA dual-input microinverter, with a 5 m cable (10 m costs £39.99 extra). Thunder quotes ENA Connect Direct reference THUNE/21204/V1. On 9 November the register showed six compliant Thunder entries (THUNE/21748 to 21751 among them), which include a flat roof variant.

The catch is that Thunder also sells Bolt Plus and Storm Plus models with a battery. Those are outside the plug-in regime. Buy the Bolt kits for plug-in use and check the product page names a battery-free kit.

EcoFlow

EcoFlow’s UK store sells the STREAM 800W Microinverter Kit. The microinverter alone was £549 when we read it, a sale price against a normal £678. Bundles with panels cost more. The output is listed as 800 VA at 230 V. The ENA register lists two EcoFlow entries as compliant, both dated 22 September 2026.

Here is the conflict. EcoFlow’s own UK FAQ says that, because of local regulations, the BKW DIY cable used with the STREAM microinverter must be connected to the distribution board, and that this needs a professional installer or electrician. A kit that needs an electrician at the board is not the plug-and-play route this guide covers, even though the register shows it as compliant. We have not been able to resolve the difference from public pages. Ask EcoFlow how your kit connects before you buy, and do not assume the plug-in route applies.

EcoFlow PowerStream and the Battery Models

You may be searching for the EcoFlow PowerStream by name. We have not read a UK listing for it, so we say nothing about its UK status. EcoFlow’s battery systems, the STREAM Ultra X and STREAM 5000, are listed on its UK store with batteries, so they are not plug-in kits. A third-party report we saw says the STREAM Ultra UK variant reaches up to 2,300 W AC, which we have not confirmed. Either way, a battery in the unit takes it outside the plug-in definition.

Zendure

Zendure’s UK store, as read on 9 November, sells only systems with a battery: SolarFlow 2400 and 3680 models, from 2.4 kWh up to 8 kWh and from 2,400 W up to 3.68 kW. Zendure describes them as “UK-Compliant ENA G98 Bundles”. With a battery and more than 800 W, they are not plug-in kits under the rules above.

The register tells a different story. It lists six Zendure entries for a SolarFlow 800 with two panels as compliant, dated 21 September 2026. We did not see the SolarFlow 800 for sale on the Zendure UK store. A third-party source reported pre-orders from 2 November, with the battery “to be confirmed”. Treat the SolarFlow 800 as on the register but not on sale until Zendure’s store lists it.

Anker, Jackery and Renogy

We found no entry for Anker, Jackery or Renogy under the Plug-in Solar type on the register. That is a statement about the register, not about their products.

• Anker SOLIX. A third-party source reported a UK launch only when regulation allows and found no ENA entry. We could not confirm a UK plug-in product.
• Jackery. No plug-in entry found on the register.
• Renogy. A third-party report says Renogy claims G98 and ENA compliance for a battery-based Plug-In Solar 2400. We could not verify the claim, and the same report warns that systems with a plug-in battery are not covered by the plug-in kit rules.

If any of these brands publishes a compliant, battery-free kit, we will add it with the date we read it.

Also on the ENA Register

Some of the biggest names on the register are installers and distributors rather than household brands, and we read no prices for them. Compliant entries on 9 November: Worldwide Solar 31, Perlight 18, City Plumbing 13 and PatioSun 6. Thunder and Zendure had six each. The register also holds non-compliant entries, so always check that the exact model you are buying is marked Compliant.

Which Brand Is Right for You?

Use the rules as your filter, not the logo.

1. Want a plug-in kit now, battery-free? Octopus and Thunder both sell kits with a compliant register entry and a three-pin plug.
2. Considering EcoFlow? Ask how the STREAM connects. If it must go to the distribution board, it is an electrician job.
3. Considering Zendure? Read the product page for the battery and the output. Larger battery systems are a different product.
4. Want the lowest price? See the table below, which shows what each brand lists today.

Prices on the table come from each brand’s own store as read on 9 November 2026 and may have changed since.
