Stand improvement need

I hear that EcoFlow is working on a better stand solution for this. Hopefully it will either be free for those who have already purchased the 400W panel or very inexpensive since I have already paid $1199 for this.

Scarlet Snow

We have had 3 of the 400W solar panels outside for 125 days straight, rain, snow, hail, high winds, and no issues. They actually can stand up to sustained use in weather! I've had them flat on the ground and now on the side of a small rise. Running them in serial. I've gotten up to 960w, yesterday I got 940w late morning. For 2 months they powered our seedling far in the water shed (pictured to the right in the photo) . Lately they power up all our battery recharging operations - our water filtration and our freeze drier.

I am very impressed with the Echoflow foldable solar panels. Well made, meets or exceed all specs. I like that the panels are built for the Echflo pro product and I don't have to gerry-rig 3rd party solutions..Be aware that they are soldi built which makes them heavier than other similar panels.....just goes with the territory if you want quality..........In-addition.....I am always impressed with the customer support EchoFlow provides....I know I can always get an answer to my questions either through customer support line or the EcoFlow Delta Series Group, face book page ..I highly recommend all of the Echflow product and anxiously waiting for new products that can augment my home power needs.....

EcoFlow is the future

Worth every penny. This solar panel has changed the way I use my EcoFlow max. amazing working art. It even gives me 370 watt in day cloudy day. My generator is always 95-100 topped up. During the day. Just need a little bit of light and they power up. Highly recommend. I dont get paid for this survey and not sponsored. My personal experience. They deserve 5 star. I ordered my 2nd 400 watt panel.

Excellent solar panel

Excellent Solar Panel, very good power output... when I tested, I was getting about 350 watts out of each panel, all without even trying hard to get the angle right. Would definitely recommend.
