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 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.

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)
