Solar Panel Wiring Basics | Maximizing EcoFlow Delta Pro Solar Charging

When starting off in solar it is easy to over-simplify the selection of the right panels to match up with your solar generator, charge controller, or string inverter. I will walk you through an example where I will use wiring in series, parallel, and series-parallel to try and get the most solar input power to charge my EcoFlow Delta Pro.

This is one of the best explanations I have seen on the differences between series, parallel, and series/parallel solar panel connections. Your drawings and explanation were very clear and easy to understand. I do feel you left out a couple of important pieces of information for people to realize when they are determining how to wire their panels and what to expect from them. The first thing is a realistic expectation of how much power they will get from a given panel. Most panels will output somewhere between 80 and 90 percent of their rated capacity. So, your panels had a theoretical max of 1, 440 watts, but when you multiply that by .85, to account for efficiency losses, you get 1, 225 watts. That's about the most anyone should expect from those four panels, no matter how they are wired. The other very important consideration when deciding how to wire up your panels is shading. If your panels don't have bypass diodes to address shading issues, then wiring in parallel, or series/parallel, can ensure you get at least part of the output from your solar array, when the array is in partial shade.

This is the clearest explanation and example I’ve seen.
For anyone teaching this subject, please take notes. This is how it’s done.

To make it easy; panels in series the voltage adds up current remains the same. Panels in parallel, the current adds up voltage remains the same. Nice production. Also more sunlight equals to more output. But you have proven which method is efficient under the present condition.

Dude, this video is the one ive been looking for for the past almost 2 years. Thank you so much for breakfast it down as simple as possible.

[KismetBP]

You are wonderful at explaining things. I actually understood this with zero experience with solar panels. Thanks! I blame YouTube for not suggesting me this channel earlier. ❤

[ВладимирПутин-ем]

Excellent example. Love the simplicity you apply to this example. Many of us are not 'experienced electricians', so keeping it simple is GREAT. thank you for making this video.

[chrisst.pierre]

Thanks for making this so easy to understand. Really appreciated.

[loucinci]

Nice job. Helpful. Something to add at the end would have been solar panel tilt into the sun (beer can on panel leaves no shadow ) to see the max power you would get. Thanks for sharing

[BZackheim]

This is the best explanation I've heard for this solar generator's requirements. Thank you.

I finally found a video that breaks it down to where it makes sense! Thanks!

[lovenotcult]

I read the comment below that you agreed that these panels' specs aren't the optimum choice for the Ecoflow due to the Eco limitations. I just got the Pro and would like to know what specs to look for.... and in four 400 watt panels to get the closest to 1600. And your drawing is the clearest wiring explanation yet - I haven't understood ANYONE else! Thank you!

Great video. Something I was hoping you would mention is that in series, if even one panel is obstructed with shade, it reduces performance for the whole string. Parallel wiring allows each panel to fall into shade separately. But again, there are pros and cons to each approach. Also, a general statement, is that panels need to be kept clean to perform as rated. Hosing then off or even brushing them is good maintenance but hard to do on the roof. For this reason, I am very interested in mounting at ground level, or somewhere I am comfortable reaching on a ladder.

I always thought the current was the Imp if u connect in parallel .Thanks again, learned something

I am just now putting a small system together for some lights, a desktop and maybe tool charging, not big draw
I went with Four 100W panels, into an 150/40 EPEver charge controller and Four 105 amp hour deep cycle batteries to kind of keep cost down, for a few days I was running them in 3P didnt bother with the last one it was just working, and even under load with clouds it was doing good, I can use everything for 6 to 8 hours with 1000W inverter and only draw down to 12.1v but if I can get a little better out of them on a little cloudy day, SWEET! I will try 2S2P
next I will drop wown from 12 Ga to 10ga for even a little more percentage :)

Finally, intelligent life in the solar panel world! Thank you very much. Can anyone recommend panels for EccoFlow Delta Pro, best bang for the buck?

[NAVY_NFO]

Great video! It really drives home the point that your system needs to be designed with the parameters of each piece of equipment in mind so that you can achieve maximum performance (i.e., efficiency and effectiveness). The PV panels you choose need to be well-matched to hybrid inverter/controller/charger or whatever load you choose. As I have found in my research and readings, there is a lot more to designing a solar system than immediately catches the eye., and this isn't even touching the NEC regulations for grid-tied solar systems. Regardless, great job...very informative at the pragmatic operational level. Thank you!

[markwhite]

I just bought my first solar generator. This helped me out a lot

[williamlopez]

Congrats!!!. Tis is the most explicit video I ever seen regarding solar power connection.

[geod]

Looking at your drawings really helps me to understand whats going on.
