Customer Reviews for EcoFlow - 400W Foldable Solar Panel - Black

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.

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.

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)

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!

Stand-alone portable DPU with portable solar panel

I bought one portable EF 400-W solar panel and tested I for “real output”. I liked it so I bought a second panel and connected it to my DELTA Pro Ultra. Yesterday’s two panels in series produced 3.16kWh of solar energy on a sunny day. My only concern is how long will the folding panels last, when compared to the fixed panels. The big plus is that the entire system is portable, so it can be moved if/when I change locations or go camping. The DPU is a bit heavy, but a small dolly can be used to assist in moving it. Proprietary connections on the inverter and battery may limit connections to future advances or improvements, but they also make it very simple to setup and get the system running to support a small home office.

I have a Delta MAX and the River Plus and you cannot charge the River Plus with the 400W solar panels. This information needs to be explained on the website. Either you have to charge it with the Delta MAX or buy a lower wattage solar panel to charge it. That's ridiculous!

I purchased this item a few weeks ago, but have not had the opportunity to use it yet. I am a novice camper. I can consider myself a first generation camper or explorer in my family. But even though I only have a few camping nights under my belt, I was impressed with the information that I was exposed to online from the reviews of other customers and fellow campers. I really enjoyed the idea of winter camping and I am sure that the solar panels in conjunction with the EcoFlow Delta 2 which I have also recently purchased will be a great combination. I am planning on creating my first YouTube video which will consist in the unboxing of the 400 W solar panel from EcoFlow as well as the EcoFlow Delta 2. As part of a winter camping video series based on New Jersey’s state park campgrounds. I am very eager to see the results of both products. Hopefully, I will inspire other family members to enjoy the beautiful outdoors as well as the different EcoFlow products.

Works great. Need to be very careful with this. Holding rings on panel itself elongate if you allow them to hang some weight.
