Plug and play
I bought this 4 months ago and things could not be better. All panels work as expected.

Excellent product
I purchased 4/400 W solar panels for my Delta Pro and I couldn’t be happier.

Solar panels
The two 400 watt solar panels are great. They have been recharging the Ecoflow battery easily now that I have them mounted on my catio.

Rigid Solar panels
Love these panels! Only issues I would fix is longer cords. These are really short. 2 feet would be nice or at least a foot.

I’M BACK AGAIN
Check the reviews! This is my 3rd purchase of the 400 watt rigid solar panels. There are cheaper options, but they WON’T produce the power that these panels do. I consistently get more than the rated power from these panels. These 6 panels puts me up to 18 in total now. The 12 I currently have running add up to 4800 watts. I get 5200-5400 all the time. As the saying goes…give 110% EcoFlow actually does!

Best panels I’ve ever seen
These two high performance 400W panels were a gift from my daughter and son-in-law. These panels are impressive, even in cloudy conditions. Now my DIY project is to take our Refrigerator off the grid. Test results with a 48v 2.1kwh battery were great. I’ll upgrade to at least 5kwh and see how it works for some overcast New England weather. Maybe these panels can cut the 2kwh per day refrigerator consumption by 75 percent maybe.
