How to compare these options
Great Britain plug-in eligibility: register checked 8 September 2026
Northern Ireland has a separate connection route
Product and link review: 10 September 2026. Register status remains the dated 8 September record. The UKSOL £599 price is from the retailer check on 4 September; Argos blocked our latest automated check, so current price, stock and delivery remain unconfirmed.

| System | Price | Panel / input / output | Battery? | Smart App? | Best For |
|---|---|---|---|---|---|

| EcoFlow STREAM Microinverter | Check selected bundle | 800W AC output | None in the microinverter | Yes — EcoFlow App | Comparing battery-free EcoFlow hardware |

UKSOL Plug-In Solar Pro Compact 515W
panels
1 × 515W (hybrid mount)
inverter
800W-class microinverter (register capacity 0.8 kW)
connectivity
Not stated on the listing
warranty
Not stated on the listing
weight
Not stated on the listing
Features to compare
- +Assessed Compliant on the ENA register (UKSOL/21008/V1/A4), so it can legally use the plug-in route
- +Argos listing recorded on 4 September; check current stock and delivery terms
- +The lowest listed price among the six UKSOL Argos bundles in our 4 September snapshot
Limitations to check
- −Single panel, so less generation than a two-panel kit at similar money
- −We have not conducted long-term testing; current retailer stock could not be reverified in this review
Verdict
A useful starting point for a Great Britain plug-in kit: the exact register reference was Compliant at the maintained 8 September check. Confirm the listing still matches that model, then compare mounting, panel area and the full installed cost against other verified kits in our tracker.
EcoFlow STREAM Microinverter
output
800W AC on the linked Amazon listing
battery
None; battery STREAM models are different products
connectivity
Wi-Fi and app control
Features to compare
- +Monitoring through the EcoFlow app
- +The linked Amazon listing is for the microinverter, not a battery bundle
Limitations to check
- −EF-PS-800 was Non-compliant at our 8 September register check
- −Check the model, cable, included panels and installation route before ordering
Verdict
Do not confuse STREAM with the older PowerStream or assume a retailer listing establishes plug-in eligibility. Battery models need a conventional installation; this microinverter also lacks verified plug-in status in our maintained register snapshot.
Anker SOLIX Solarbank 2 E1600 Pro
input
4 MPPT, 2,400W total PV input
output
800W on-grid AC
storage
1.6 kWh, expandable to 9.6 kWh
warranty
10 years on the manufacturer page; confirm UK seller coverage
weight
21.8 kg
Features to compare
- +Four MPPT inputs for separate panel groups
- +Storage can be expanded; it is not fixed at 2 kWh
Limitations to check
- −Battery storage excludes it from the Great Britain plug-in route
- −EU specifications do not establish UK cable compatibility or installation approval
Verdict
A storage option to assess with an installer. Compare the exact Pro model, included panels, installed cost and warranty territory. PV input capacity is not AC output or a prediction of annual generation.
Plug-in Solar 600W Kit
panels
2 × 300W monocrystalline
inverter
Hoymiles HM-600 micro-inverter
connectivity
None (inverter only)
warranty
2 years (varies by seller)
weight
~16 kg
Features to compare
- +A battery-free configuration for comparison with conventional installations
- +Hoymiles micro-inverters are well-regarded in the solar industry for reliability and longevity
- +Simple, proven technology — nothing to go wrong with an app or cloud service
Limitations to check
- −No monitoring app — you won't know how much electricity you're generating without a separate meter
- −No battery option, no smart home integration, and support can be limited through third-party sellers
Verdict
The name does not establish plug-in eligibility. This configuration is not verified in our register snapshot, and we removed an Amazon link that resolved to a different kit. Get an exact model and installed quote before comparing costs; the certification tracker provides dated alternatives.
Jackery Navi 2000
panels
Up to 800W PV input
inverter
Integrated 800W
connectivity
Bluetooth + Wi-Fi
warranty
3 years
weight
~12 kg
Features to compare
- +Compact footprint makes it the only viable option for Juliet balconies and narrow terraces
- +Jackery has a strong reliability reputation built on their portable power station range
- +2 kWh LiFePO4 battery expandable to 8 kWh for serious storage capacity
Limitations to check
- −Not yet available in the UK — currently sold in EU markets only
- −Newer product with less long-term reliability data than more established systems
Verdict
The Jackery Navi 2000 is a promising balcony solar system with up to 800W PV input and expandable LiFePO4 battery storage, but it is not yet available in the UK. We'll update this listing when UK availability is confirmed.

Evidence and comparison limits
This is a desk comparison. We use the maintained ENA record for plug-in eligibility and manufacturer or retailer documentation for the named configuration. We do not assign test scores or claim that every product has been independently reviewed. Battery systems are included to explain alternatives, not to present them as certified socket-connected kits.
For each shortlist, check mounting permission and load capacity, panel dimensions and shading, the included inverter and cables, warranty coverage, delivery territory and electrician costs. Compare annual usable generation with your daytime consumption rather than choosing solely by maximum wattage. Our savings calculator models assumptions, not a guaranteed return.
Sources checked 10 September: EcoFlow UK model range, Anker Solarbank 2 E1600 Pro manufacturer specifications (EU specifications; verify UK supply), DESNZ final specification and NIE Networks’ distribution code. Retailer links identify products, not proof of compliance or an order.
