I have been happily using common crimp terminals for my wiring changes up to now. I have used a lot of yellow, blue, and red butt connectors. That changed with my purchase of a Goal Zero 1000 that makes use of Anderson Power-Pole PP) connectors. Not having used that connector to date, the GZ got me digging into the information regarding the Power-Pole connectors. I really like them
Common PP sizes are 15, 30, and 45 amps. I have the 12v
max cable for the GZ that will supply 40 amps of 12v
to my AI 12v
system. The output connector on the 12v max is a PP 45 amp pair.
The PP connectors are much more secure than anything I have used before and are arc-resistant when plugging or unplugging. They can be applied without a special tool, with care, but I went ahead and ordered a $35 crimping tool. Accessory cables with the PP ends are expensive, but the raw connectors are very reasonable.
I had been intending to put a switch in the hot lead from the solar. Instead, I'll just insert a 45 amp PP in the line.
