Ecoflow UK Support & Info Thread
We’re opening up an official support forum for EcoFlow products on Renewable Heating Hub.
Given how quickly the portable power and home storage space is evolving, it felt like the right time to create a dedicated space where owners (and those considering a purchase) can share real-world experiences, troubleshooting tips and ask questions without wading through generic advice.
We’ve also got a review of the EcoFlow DELTA 3 Max coming up shortly, which I’m particularly interested in given how these systems are starting to blur the lines between portable and whole-home backup. The Delta 3 isn't a whole-home backup, but it's a really interesting product for our particular lifestyle.
So, if you’ve got questions, things you want tested, edge cases you’re curious about or even concerns you want properly put through its paces, drop them in here. I’ll try to incorporate as much as possible into the review rather than just doing a surface-level overview.

I’ve been googling some reviews of these (and looking at the Amazon pricing). The main feature of several of these balcony solar products is they are all out of stock(!)
2kW + Growatt & 4kW +Sunnyboy PV on south-facing roof Solar thermal. 9.5kWh Givenergy battery with AC3. MVHR. Vaillant 7kW ASHP (very pleased with SCOP >4) open system operating on WC
They need to stock up for those rainy days I suppose!

I'm toying with the idea of Ecoflow Streams but I've not had the courage to get my wallet out just yet. I've got an inverter with 2 panels and its working great - but battery wise I'm still not sure what's best and surely very soon there will be a lot of competing systems.
Also the ecoflow website is very difficult to understand which battery is witch, they all look the same and are named the same, it's very confusing.
@sonosppp I've just recorded my review of the Delta 3 Max and I have to say it's a very polished product for what it does. Far from a being a home backup system, but I found it very handy. The review will go live next Wednesday once it's fully edited.
