New to Solar. Help with 3 Line Diagram/ Wiring Diagram

[inetdog]

It appears there are three strings of collectors in the array. [ATTACH]2020[/ATTACH]

Are we looking at the same diagram as the photo in the post? I see one series string of more than three panels, all with a common protective ground.

Thanks for the imput. I'll look into fixing those errors on the diagram. My boss is an electrician by profession and I am apprenticing under him to learn all the terminology. I know its not all about the software, and right now I have a basic knowledge of electric as I have only worked 2 jobs with him. I plan to learn as much as I can so that I can help him with these diagrams. He asked me to help him because he knows that I am fairly savvy with computer programs and such. I have plenty of time to learn how to do these diagrams; like I said I am in no rush.

As for the computer programs go- whats the best one for making 3-line diagrams?

OK a couple of things wrong on that drawing
It appears there are three strings of collectors in the array. This will require a fused combiner.
Second sizes of conductors are not specified.
No bonding is indicated.
No specification on the size or ratings on the buss bars of the panel.
Input location for the breaker from the inverter is in the wrong position. Should be at opposite end of panel from main utility breaker.sample one line.pdf

Do you have any background in electrical? Software is the asy part - you need to know what you are doing.

Hello,

I am new to solar but I have been working with someone who has been working with solar for years. He has taught me a lot about solar and I am interested in learning more. Recently he has been trying to get me to study 3-line diagrams because he wants me to be able to create them for some of our future jobs. I realize that this will take some time getting used to, and I am in no rush, but I don't think it would be that difficult to get the logistics.

I have a few questions....

1. First of all, what would be the best program/software to work on a 3 line diagram. I can buy whatever, but I want whatever program makes it the easiest.

2. Should every 3 line design be different for each job? Do they correspond with a diagram or map of the house or are they meant to be rough examples of how the solar wiring would be on a house.

3. Whats the best way to learn the software for creating a 3 line diagram? Should I just play around and see if I could figure it out on my own? Are there any tutorial videos out there teaching you how to create a 3-line diagram?

Like I said, I am new to solar, but I want to learn as much as I can. I want to be able to help my boss by creating these diagrams and making a little extra cash. I have seen many basic ones that he or someone he knows have created and they are fairly simple. I almost feel like I could recreate it in MS paint, but I know there are easier programs for doing these diagrams.

I am from Westchester county in New York and below is a design that my boss made that was declined by the Rockland county engineer. What is this diagram missing that he should have put on it? How can I make this design pass inspection?

Thanks for any help.
