EcoFlow EFSOLAR400W Reviews
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.
Soloar panel
Panel Works great with the delta pro and extra battery
My condo in the city is now mostly off grid. Wild.
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.
Reality Check
Be sure it works very well BUT be careful of the (PORTABILITY). THAT has been pushed way two far. I picket it up then looked for the closest place to put it down. Weight X Bulk or Size. = 90% of maximum. Very awkward to handle. If it had been designed two panels the same dimension's with plug and play totaling four. That would be great. That would be (PORTABLE) That would be (5 STARS). But it works VERY WELL.
A bit disappointed
400 watt folding panel, noon, cloud free day in Florida, angle set to be perpendicular to sun, max power generation according to the app, was 260 watts. two consecutive days. Panel gets very flexible in the heat, if even minor cracking occurs efficiency will drop.
Use with both my Delta Max and my RV controller
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.
Best high watt portable panel
Pro: It is one the highest wattage portable solar panels you can buy and of good quality. It has a nice but very snug fitting zipper carrying case and panels are thin and look nice as well. Has IP68 waterproof rating and 22.4% conversation rate. The MC4 connectors have an easy quick squeeze to disconnect. Decent cell app to monitor solar watts. Con: This foldable panel is at the high end of portable @35lb weight. Shoulder straps make it easier to transport. But it might be difficult for some users to move and setup depending on your physical ability. I sometimes use a hand truck to move my 3 panels to my back yard. The kickstand case works but is not the optimal support. It�s much quicker and easier if you have a second person assisting setup. I am trying alternate options to support the panels. The case as a kickstand design is my biggest compliant. I hope they replace the kickstand with an improved retro fit drop down legs format support. The warranty is short at 1 year compared to rigid ones at 10 years. Comments: Using the EcoFlow angler device improves obtained wattage. With a bright Florida December sun with air temp of 50 degrees, I have gotten as much as 350+ watts. If you purchase multiple items at once like I did, they sometimes offers combo discounts. Overall, I am happy with them. So depending on your intended purpose and location of use and power needs, these 400W panels might be the right fit for you as well.
Worth it!
Super easy to use flat or even with the included stand. Charging in a zip too. You can PARALLEL connect 4 on the Delta Pro.
