It's more than enough power to run my kitchen from my south-facing balcony in California. And that's wild. We are making power plants irrelevant. It's a whole new world.
I would recommend this to a friend!

Builder with my RV only installed a PWM 50 volt/11 Amp max 780 watt controller so can use it but disconnect roof panel120 w and have had a Outside connection to controller ,sertup now works great, very impressed with my Delta Max and 400 w Solar Panel , soon when we get the new Power Hubs and 10 Kwh batteries will cure alot of problems running out of batteries, my Thai RV is setup to take on new Power Hub unit , hope it comes in the next year builder built a 62 volt lithium battery inverter and cannot use solar panels,no Charge Controller built to handle 62 volts.

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

Gender:Male
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.

Big. Fairly heavy….but yea, portable. Panel Flexes back a bit when using the case as the stand (all there models do, I have the 400, 220, 160, and 110s). Typically get 300 watts laying flat and not adjusting. Happy enough about that. Running two in series I have seen 650 as a high, again flat and not accounting for tilt and angles (and they are fairly dirty).

Great panel with performance that out shines other 400 watt panel systems. EcoFlow backs up its products with excellent customer service and rapid feedback on any questions or issues. This is the solar panel to buy for its ease of mobile deployment, power, and durability.

These were easy to connect and so far work very well with no hassle. They pick up the sun as soon as it appears, even laying down flat.

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.
