Great so far
Haven’t used any of the gear yet apart from topping up the charge on the delta 2 which seemed nice and quick. The app is very good and adds another level of control, all in all so far very happy. Arrived quite quickly by courier and post
Great battery I was hoping for 3 full days for my fridge in van. But got 2 days. Quiet and easy to use.
Absolutely satisfied with our Delta 2 Max and 400W solar panel. The panel charges fast even in deep winter, and the Delta 2 Max has become the heart of our off-grid system. We’re running it alongside our older solar setup, and it integrates beautifully. Reliable, powerful, and easy to use — this combo exceeded our expectations!
Got 7 in total, 2x delta 2 pros with extra batteries, 1x delta 2 max, 1x delta 2 and 1x river 2 max. Also got a ev x-stream adaptor for the pros. Been running my home now on these for 3mths, and they haven't missed a beat. Charging units from grid because i get a 3hr window of free kwh. Thanks Ecoflow, great products, also customer service is top notch.
