Seeking a little help

We are doing a commercial install which includes 207 SolarWorld SW230 modules with a SMA ST42 inverter. I have all the string sizing complete but I need a little help in doing the wire sizing. I also need to know if anyone knows of a place I could get a copy of a construction plan or something to look at while I complete the cad drawing.

Take a look at Outback Power's Website... They have a bunch of simple electrical drawings for various types of system.

By the way, you only need to post once... Forum is small enough where pretty much everyone reads every post.
