3 x 400W panels outside 24x7 for 125 days straight

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 will use for emergency charging only...

I live in Japan and purchased the Delta Pro / Solar Panel combo. I set up the solar panel by myself and found it quite a cumbersome process. The case is to be used as a "stand" but it was rather tedious to get the panel connected at the 4 attachment points AND attempt to get the panel to sit correctly in the case-stand. After connecting the carabiners to the grommets I feel like there is quite a bit of tension/stress placed on the grommets and I would be concerned about long-term regular use. Seems like a weak point in the design but hey - I'm not a design Engineer. Directions say to zip up the case to adjust the angle of the panel but I'm in a location where I can just leave it completely unzipped. I didn't attempt but I would imagine trying to zip up the already flimsy case while holding the panel would be very frustrating. Two people working together would stand a better chance at not feeling like they deserved an ice-cold beer after wrestling with it alone. Overall build quality seems excellent and I'm glad I have it in case I need it but I hope someone can improve on the design moving forward. Cheers.

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

Solar Panel Package Review
on September 15, 2022
Posted by: Arizona Son

The Solar Panel Package is well packaged and has carrying straps. The panels cannot be separated so are a little heavy to carry. The Panels are well built, very efficient, and charge the battery as advertised. When laying them out flat, in midday on a lawn, put spacers underneath so the hot panels will not kill the grass underneath them. They are well designed, efficient, and portable.
I would recommend this to a friend!

Works OK, a little heavy and I wish it away to stand it up at an angle, I havey another power station and the solar panels have some brackes that let you stand the pannel up.

Solar Panel Kickstand needs a lot of improvement
on August 12, 2022

I bought my Ecoflow Pro, Wave, and solar panel system several months ago. The Pro unit seems great, the Wave needed a cable that finally arrived, and does cool very well. I think the main systems are the best on the market right now and the most innovative.
This said, however, I think there are needed improvements in the little things. The instruction manual should go over every little part and port on the units and what they are used for. For example, that the extra battery port is also the port used to plug in the Wave. The "kickstand" for the solar panels is awful! Whatever stiffening material is inside, melted/warped in the hot sun here in Central California so I can't use it when it's hot (basically ALL summer) and prop the panels up on kid sized plastic lawn chairs instead, which works easier and better anyway. While using the "kickstand" it's extremely difficult to move the panel with the sun. They catch on the grass and bend and wave or scrape on the pool deck and get scuffed up. The ends of the panels are not supported and bed back and don't stay at the optimum angle to the sun. I'd really like a hard case for more protection of the panels, and a true stand solution. I also have a Lion Energy system and their case and stands are VERY good. If you need help with design of a new stand and/or case, I'm positive I could help you. A simple folding metal frame system would work as well as my little chairs. A MUCH longer charging cable is definitely needed. I bought one on Amazon so the Pro unit can be in the shade or even inside my home and the panels can be in the sun. I covered all the cables with swimming pool noodles (cut down the length to slip the cables in) to protect them from the extremely hot sun here and it worked great. I gave Ease of Use only three stars because of the hassle with the solar panels. If not for the awful "kickstand" I'd have given 5 stars. For the same reason, I only gave 4 stars for rating the fast charging system. Too much time was lost trying to get the panels set and the same for quality. The power units themselves get a definite 5 stars, but the panel stand system brings it all down. If the solar panel stand really worked and the instructions more thorough, I'd give 5 stars on everything.
I would recommend this to a friend!

Panel Great stand not so much.

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 .
