Good product for portable solar power uses.

Performs well and as expected. It has a good conversion rate/performance. I have good sun exposure most days of the year and can recharge in 4-5 hours when 2/3's expended. The panel array is heavy and awkward for single person manipulation. The panel array gets warm as would be expected in the sunlight and so if laid out over vegetation that you care about, (lawn, etc) it will burn the vegetation - I have had the same issue with a generic tarp on the lawn. So I purchased an adjustable stand ...

EcoFlow is one of the very best values in industry

Purchased an EcoFlow ultra extra battery with inverter And several different EcoFlow solar panels, including the 400 W with a gimpy stand. One piece of advice if you’re getting into Solar is unless you’re selling XS back to the electric provider. It’s not going to be cost-effective. One way to help it be more cost-effective is to never pay full price for solar equipment. Wait till Black Friday wait till Christmas wait till summer wait till Easter Memorial Day Labor Day check on all the major hol...

Need better stand

I bought a Delta Pro and four 400 watt portable panels. The bags they come with are nice for transporting the panels but I have a very hard time using the bag as a stand. Really wish you offered a separate light weight adjustable stand sized properly to work with this panel. November 2024

Great product. Works well

Solar panel is solid and well made. It provides a welcome and practical alternative to a gas powered generator.

New solar generator hookup.

I hooked up the solar panels to the charger today. The panels and charger are on my in full sun. Started at 29% battery and now is at 42%. Charges at a slower pace. It’s been charging for about 2 hours. I have four panels for 400 watts.

Great-right out of the box

We have a class b camper van. On a recent trip during the summer heat wave we put out our 400W solar panel connected to our EcoFlow delta 2 and then plugged in our RV. Charged our delta 2 as well as our house batteries. We had all the juice we needed. The panels were heavier than i like but were manageable and well made.

400 Watts pannel

We've had this 400 watt panel for a few weeks now and love it. We previously had two of the 220 wats bifacial panels and loved them but this one has been a game changer for our charging ability.

EF 400W

Purchased this unit (DP) to act as partial backup to home using the EF 400W portable panels. The initial base line testing has been completed and the unit performed well. Will have final verdict after a few more weekend tests. The solar panels seem well built. The dual purpose kickstand is a little tough to use and does not show good value unless conditions are ideal (which is almost never the case)

Love it

I set mine up on the roof of my house and use a 20ft extension. It hasn't moved even during storms. I have one of the early Delta models, and it works great. I just need a bigger battery. As the sun first rises, I only get 20-30 watts and peaks over 300 watts around noon. Considering the panel isn't pointing directly at the sun, I'm impressed!
