Theczar - because you will be running wiring for a 30A solar system I recommend you purchase the Andersen Powerpole PP45. The wiring hole for the PP30 terminal is a bit too small for the size wire you should be using ( 10 guage ). Note, the plastic housings for the PP15, PP30, and PP45 are all the same and all mate with each other.
I also recommend you purchase a crimper from one of these two sites:

The dcpwr.com people are a small business and have particularly outstanding customer service in my experience.
