Friday solar panel shopping

.

I sent an e-mail off to Bogart, and was surprised to have Ralph call me up to discuss my system with me. I just sent both my Trimetric and controller back to him to have them re-programed prior to my installing the second SC2030. Talk about good customer service.

What size wiring did you guys run from your junction box to the controller? I started with 4 100 watt panels, and only went with 6 awg wire, expecting a run of around 15 feet. In the end, it's closer to 20. I since added two panels maxing out the controller, and have 4 more panels to install when the weather permits. When I go up to two parallel systems of 500 watts each, I'm debating two separate 4 gauge runs rather than just adding an additional 6 gauge run. Not sure it's worth the trouble though as I doubt I'll hit max draw often due to batteries already tapering off on what they'll accept prior to reaching peak sun. I'm adding the additional panels more for late in the year, cloudy days, days with shading large parts of the day etc. My experience so far is that these days are much more common than I initially anticipated.
