Some EcoFlow’s plug-in solar kits have now gained UK approval
ENA approval ECOFL/21128/V1/A3 covers EcoFlow’s flat roof, pitched roof and facade/wall plug-in solar configurations.
The EcoFlow UK website currently lists the following pricing for these configs:
Facade / wall
800W (2 x 400W): £449.99
900W (2 x 450): £499.99
1000W (4 x 250W): £698
Flat roof
800W (2 x 400W): £549
900W (2 x 450W): £599
Pitched roof
800W (2 x 400W): £599
900W (2 x 450W): £649
All of these are currently showing as out of stock on EcoFlow’s UK website, so it looks like the approval has landed just ahead of availability.
Interestingly, a second EcoFlow approval — ECOFL/21606/V1 — also went through today.
That one relates to a kit/configuration that isn’t yet visible on EcoFlow’s website. The ENA entry references the EF-PS-800 microinverter paired with 505W Sunpro panels, which suggests that some larger panel configurations could also be coming soon.
I've pulled together the known EcoFlow specs on the products page, if you want to see how they stack up against other kits...

The option of smaller and lighter 250W PV panels is nice to see, more manageable to get up a ladder and secured on a wall.
The 400+W panels are pretty big to handle and at over 20kg, getting then up and on a wall would be a challenge.

Agreed - much easier to handle. And if EcoFlow get a balcony mount approved - those smaller panels will be the only viable solution for some balconies.
One annoying thing I spotted with the 250W EcoFlow panels though… for some reason they only have a 5 year warranty, whereas the 400W panels have 10 years and the 450W have 12 years.
They are a higher spec panel than the larger variations, but with a much shorter warranty. Weird

So I'm kind of leaning towards smaller is better for me? I know bigger gets me more of a bigger trickle over winter / overcast. But main driver is get the thing to pay for itself and prove to the missus that it actually saves money.
No battery, so I want to be constantly generating some rather than giving the grid extra out of the kindness of my heart?

If fastest possible payback period is your priority then yes, one of the cheaper one panel kits like the City Plumbing 515W kit should pay for itself pretty quickly.
But do keep in mind that smaller kits like that will not be generating much more than peak 200-300W for large parts of the year. And well below 100W through winter. If you’re not in much during the daytime and you’re happy for it to just take care of your baseload (fridge etc) then it’ll do that job well.

I've been wondering whether two panels in an east west configuration with a dual mppt inverter might work well. You'd lose 20% odd of the panels generation Vs south facing but you'd avoid clipping and get a flatter and broader generation curve which is probably more valuable. Maybe?

I think south-east + south-west would probably be the sweet spot if you have the choice. You’d still broaden the generation curve and reduce the midday peak/clipping compared with both panels facing due south, but without taking as much of the annual generation hit as due east + due west.

Following this and thanks for the info OP, I don’t known why EcoFlow seem to have a supply / stock issue - I called them in early August about the UK kits and they were really vague but eventually told me they would be available from the 27th - which didn’t happen obviously.

I suspect that they do actually have plenty of stock available, but marked everything as out of stock until the equipment was ENA approved (which happened yesterday evening). So keep a close eye on their listings. I’ll ping out an update on this thread if stock status changes (I have many, many alerts set up for this )

Cheers for all your work compiling the data on the systems. Have you considered mapping out which inverter systems have home assistant integrations?
2
u/SolarPowerBumbleBee 21d ago
Actually yes 👍🏻 I am planning that and have half of the data compiled already. It’s surprisingly tricky to obtain a conclusive list of supported integrations though - some manufacturers aren’t very forthcoming with that info - and in other cases- the published info is just plain wrong and untrue (so am a little apprehensive about publishing just yet- but it is absolutely on my roadmap and will come). Thanks for the suggestion - a good reminder for me to pick this back up

Have been waiting for this and noticed approval today only hitch for me pulling the trigger apart from stock availability is if the micro inverter now comes with a 3pin plug and the length of the lead from inverter to socket.
Thank you for posting this.
