Style: DELTA Pro+2*400W Solar Panel
Did some reviewing and vetting before making the choice to purchase. Has lived up to my expectations. A bit costly to expand the capacity, so we decided to hold off.

This system has saved me and my little off grid cabin. It was either 2k for this, or 30k to the power company up front... Glad I made the purchase. It's been running and charging flawlessly for 6 months straight. Literally life saving.

What I liked. First off, this product did exactly what was supposed to do. Recently, in Florida hurricane Milton left us without power for about 3 days. This device kept my fridge going the entire time (not on a single charge). Unfortunately, it was cloudy for a couple days after the storm so charging via solar panels was difficult. In addition to the fridge it kept our cell phones charged and enabled us to cook on a flat top. What I didn't like is that my unit came with 2 solar panels but without an adapter to connect both panels to the unit. I have since purchased but would have been good to know before needing to use it. Secondly, my cpap machine kept causing error 303 which made the generator cut off about every hr and a half which interrupted my already non existent sleep cycle. When I looked up the error I was told it could be ternate to firmware and to download the app. Overall I recommend! You will need about 3 solar panels for it to truly work for you. Am extra battery is next on the list of items to get. Also to maximize the solar abilities you will need to find a way to prop up the panels to the sun. The case out comes in is not sufficient for this task by itself.

I was a little unsure before ordering, but I’m glad I did. The product arrived in perfect condition, was easy to set up, and has worked exactly as expected. The build quality is solid, and it offers great value for the money. I’ve used it several times already and have had a great experience. I would definitely purchase it again.

I have had my Ecoflow pro for a month . Our power went out for 4 hours one day since arriving. What a blessing to have had power to operate our refrigerator and freezer. It will handle both appliances easily for more than a day . I have been charging and powering these appliances at the same time on sunny days just to lower our electric bills. I am impressed and recommend Ecoflow.

Well it worked until it didn't. I was using it as backup power for my chest freezer. I had it plugged into the solar panels as well as grid power. I had set it up using the app so that if it dipped below 50% power, it would engage grid power to recharge itself. This aspect of things actually worked really well and I was impressed. Then it started throwing an error (Error 121) and stopped outputting power. So I followed the basic troubleshooting steps and then I contacted Ecoflow. Because it's less than three months old and it's still under warranty. Unfortunately the Ecoflow said that Amazon is not an authorized seller of their products and will not honor the warranty ,even though I bought it through the manufacturer's store on Amazon. Amazon said they won't honor the warranty because that's Ecoflow's responsibility. Outside of nobody seeming to want to take responsibility for this broken product and the fact that it's, you know... broken, it works great. One of the features that I really, really like is the luggage handle that springs out when you need to move it and the wheels because it is 100 lbs. These two features make it easy to move around and that was really nice. The app seems to work just fine for what I was using it for. No complaints there. Solar panels were easy enough to set up. I'm sure this would be great for camping or RV usage. Because the solar panels are made to be temporarily placed, not permanently. There is a fabric attached to the back side of the panels as well as the carrying case, which also doubles as a prop that you connect to the solar panels to angle them properly.

When you spend $2400 on an electrical device, you should want to take care of it, not want to max it out & put it to the test. We used ours for 2 solid weeks of boondocking and it performed perfectly. We ran our furnace, lights, TV, air fryer, coffee pot, microwave, water pumps, etc...and the 2 solar panels charged it right back up 3/4 the time, even on partly sunny days (1300w inverter generators on other days). Anyone with any common sense would ask themselves, even if it would run an AC, how long do you think it will last?...so obviously we didn't even try.
