Yes, 5 of these, mc4x5 y adapter, mc4 to xt60. Make sure the xt60 is compatable with Eco flow. Eco sells em.

Controller, battery, inverter, and wiring. Oh and some sort of frame.

Quote from intesdan :
Crazy how cheap these panels are getting.
because of China, they are way ahead in the solar/battery/energy market. They can now produce in massive scale so the price is extremely competitive. Before some dumbs starting to argue, the batteries in your phone, tablet, watch, and almost all other electronics except US electric cars, are all made in China since day 1. US government won't allow them to officially open a store or sales department here, because they will just destroy all the farking expensive non sense US companies. Like the solar roof system here in US, can cost $20K-$40K easily, and the same system in my grandma's house in China is like 10x cheaper......

Looked up a diagram, so the batteries (I read a guy was using deep cycle marine batteries) and wiring can be generic, but I suspect the controller has to be compatible with these panels? Inverter as well?

I have the same questions. Hoping someone could post the needed controller, inverter and wiring from Ali that would be considered slick for a 400-800W setup.

Is this a result of broader public policy? China is the largest importer of crude oil.

Honestly if it's your first time just go with a power station that takes solar and has settings to allow you to use solar power to a certain low percentage and then AC pass through (like Ecoflow). Then all you need is a solar to XT60i cable (also in the case of Ecoflow).

You can not put 5 on a Delta 2. You can do 4 or 6.

You can only put 2 in series, so you can do 2S2P for 400 watts or 2S3P for a 600 watt over panel and 500 max into the Delta 2. With 2S3P, you will need to put a fuse on each string.

The EcoFlow DELTA 2 supports a solar input voltage range of 11 to 60V DC, with a maximum current of 15A and a maximum input power of 500W. So 5 in parallel with mc4 y connectcors and an open circuit voltage of 22.7v is perfect.

I agree with everyone except debbie downer. I just looked over my 31 purchases and all of them were accurate. They do have those flaky fake 128 GB SD cards for four dollars but other than that everything's legitimate everything is Quality. I in fact bought this solar panel from AliExpress $41 and thought I was getting a super deal I connected daily to my.Grecell 300w power source that i bought from Temu for $31 less than Amazon.

I also.bought the Yolink Bulldog water shutoff from Aliexpress for &120 less than Amazon. It came in the original box with all four sensors and hub and was delivered by of all people, Amazon.

Max current of 15A in the Delta 2 means the most you will pull in parallel is 15x22.7=340.5w. Since each panel is 5.5A, you can parallel 3 panels, more panels will not get you past the 15A limit. 2S3P is the max for these panels, but 2S2P would be most efficient.

Do you know what the word "perfect" means?
