EF ECOFLOW 400W Portable Solar Panel, Foldable & Durable, Complete with an Adjustable Kickstand Case, Waterproof IP68 for Outdoor Adventures

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 holidays and there will be major discounts. The 400 W panel advertised here is 42% off. If you built a 90 kW EcoFlow system and paid full price well they have a 45K system in their refurbished products, which I recommend highly for 20 grand and that doesn’t include your panels. It just includes five batteries for each column and inverter. Any any and all additional upgrades such as the smart two home panel and iPhone iPad display controller or extra. Like I said wait till they’re on sale. I’ve caught some items on sale for 60 to 70% off. And it’s OK to mix equipment if you can hook them together and link them you can’t tell the difference in quality. A friend of mine built a 150 kW system in my development and I’m not sure he has two of the same of anything.

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

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

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 solar panels Love the quality and the performance

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!

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.

I haven’t used this solar panel yet but I’m sure it will be a phenomenal product.

Solar panels are great and provide faster charging than I thought they would. They are extremely heavy however and I was unable to move them around well. Also, they are floppy and it is difficult to easily reposition them for sunlight. If you are not very strong and small in stature, you should consider a smaller panel set.

Fast Charging! I like my 400W Solar Panel. It charges my Delta Pro much faster that my 2 X 100W panels. It is a little big and heavy for one person to set up but I have gotten used to it.

The panel itself is a bit bulky (42lbs) if you make a brace it works very well I have gotten up to 385 watts of power. And the panel is robust. The down side to this panel is that it takes 6 to 8 min to set up. And the team that designed the stand never tried to use that piece of crap I have 3 of them modified all of them so I don't have to unfold or use the terrible stands .

This pane has been my go to panel when charging my devices. i average around 375 t9 384 watts which is very good. i now own three of these panels and i would highly recommend them to anyone looking for a large foldable panel with this much solar output. Do not just take my word for it try one and see why I love this panel so much.

These panels are quality built. They are efficient and provide good power for my Delta Pro.

I'm a huge Ecoflow fan and I own a lot of your stuff! It's all great and exceeds my expectations. But folks, the kickstand for the 400 watt solar panels needs some help. It's not sturdy and it causes the panels to sag. Your world-class products deserve a world-class kickstand. Back to the drawing board. Figure out a better solution.
