Works great, easy to store and move around

I bought this when it was on sale to have when camping to charge a Delta 2. It is very easy to setup, and worked great the one time so far so have tested it. It packs away to a nice size when I don’t need it. Charging speed was pretty quick, so even though it’s not a high wattage panel, it looks like it’s going to do just what I need.

IMHO this product is perfect for my use case EPS

I found this product to be very well designed, reliable and perfect for my emergency power system case. I especially love the fact that I can remotely monitor the battery life and control the system remotely. I love how I can extend battery longevity based on car battery lithium battery or solar panels. Echo has a number of models that provide great scalability at a decent price range. I love this product. I think it’s awesome.

Homeless

I use a gas generator in the morning to charge my Ecoflow River Plus. Then when the sun hits my solar panel it will keep up with most of my power needs until late afternoon when I need gas generator again. Solar panel not aimed directly at sun but I still get up to 77 watts input mid day

Great back up

This ecoflow is clean and quiet and works great. I have a EcoFlow 2400-Watt Portable Power Station. I really like the app for my phone where I can monitor the input and out put in real time. Regarding the value - it could be a little less expensive.

Solar Generator In, Gas/Propane Generator Out!

We have been checking out our new Delta 2 Max with add-on battery and solar panels for several days now. Very impressed with the functionality of the overall system and app. The capacity is great to get us through power outages running necessary loads sans A/C. Our gas/propane generator will now become backup to the solar backup. Hopefully, we won't have to use the loud, smelly machine in the future.

Delta II Max w/Smart Battery and 400W Solar Panels

I received everything and it all works great. I spent a lot of time researching different brands, options, performance, YouTube videos, etc. and I am very happy with EcoFlow. The only complaint I have is that the Delta II Max does NOT have wheels. EcoFlow sent me a canvas wagon where you can fit the generator inside but you cannot add the Smart Battery with it.

So far so good, with one problem

I bought this and installed it into my daughter's bus. (Schoolie conversion) It is what we wanted. The only complaint that I have is the way the cable comes out the side. you cannot stack anything next to them within a foot. The wave has a nice 90 degree cable that goes between the battery and AC but the Delta 2's cable sticks about 6 inches out the side.

Excellent Product

As expected a little smaller than my 160 Watt panel I got with my generator but the two connected together will work fine. VERY impressed with Ecoflow and would highly recommend them for your back up power needs. Works so well we're considering Solar for our house.

Only solar panels, no power station

I thought the other 1-star review that only received the solar panels was a one-off, but it happened to me too.

Nice panels

Like the new panels. Able to get 70 watts with some optimization. Of angle with one panel to test system. Hooking up two in paralle took so digging to figure out how to set up but satisfied overall
