You know how you bump elbows with someone on the sidewalk and they put a little brainstorm in your head, well thats what led me to buying the Delta Pro and the "Extra Battery" .. I use it exclusively for charging my Tesla (I don't have a garage, or access to electricity in my carport) .. Perfect solution for everyday driving for me ...

Purchased an EcoFlow ultra extra battery with inverter And several different EcoFlow solar panels, including the 400 W with a gimpy stand. One piece of advice if you're getting into Solar is unless you're selling XS back to the electric provider. It's not going to be cost-effective. One way to help it be more cost-effective is to never pay full price for solar equipment. Wait till Black Friday wait till Christmas wait till summer wait till Easter Memorial Day Labor Day check on all the major holidays and there will be major discounts. The 400 W panel advertised here is 42% off. If you built a 90 kW EcoFlow system and paid full price well they have a 45K system in their refurbished products, which I recommend highly for 20 grand and that doesn't include your panels. It just includes five batteries for each column and inverter. Any any and all additional upgrades such as the smart two home panel and iPhone iPad display controller or extra. Like I said wait till they're on sale. I've caught some items on sale for 60 to 70% off. And it's OK to mix equipment if you can hook them together and link them you can't tell the difference in quality. A friend of mine built a 150 kW system in my development and I'm not sure he has two of the same of anything.

I have a Delta MAX and the River Plus and you cannot charge the River Plus with the 400W solar panels. This information needs to be explained on the website. Either you have to charge it with the Delta MAX or buy a lower wattage solar panel to charge it. That's ridiculous!

Quality made product that will last for many years. Setting up was super easy with my Ecoflow 2.

I bought this about 2 weeks ago, did not open the box yet. I will open next week. Fast shipping. Thanks.

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.

Have not had a chance to use it, but if it works as well as my two 160 watt panels it will be just fine

Solar panel is solid and well made. It provides a welcome and practical alternative to a gas powered generator.

Works great. Need to be very careful with this. Holding rings on panel itself elongate if you allow them to hang some weight.

I'm a huge Ecoflow fan and I own a lot of your stuff! It's all great and exceeds my expectations. But folks, the kickstand for the 400 watt solar panels needs some help. It's not sturdy and it causes the panels to sag. Your world-class products deserve a world-class kickstand. Back to the drawing board. Figure out a better solution.
