And the winner is Soldacrimpador or Crimpadorsol. Go with what works for you.

everyone will give you a different argument. I personally solder and shrink. In my electronics manufacturing and then my RV tech days, I saw MANY crimped connections fail..and not a single solder connection fail in an RV. (Electronics..thats another story!)

That said, I try to solder all my own stuff, but I often live off grid and so crimping is my only quick option. I know how to do it correctly (You would be surprised how many don't) and have only had 1 failure.

To the OP..good job. I did something similar with my Burro solar panels and do the same with my Leocraft for my portable panels. I use an ASC controller and it CAN be put in the battery box. It is 100% potted so no interior components are exposed to battery corrosion. I do have to clean the exterior connections once a year or so.

Be it soldered or crimped, tinned wire is good protection against corrosion. I find most wire sold at the parts store/ hardware store, usually refered to as primary (wire) is not tinned. Ask and they won't have a clue. No matter how good you seal, water seems to find a way in. Raz

I am wondering what the wiring pin outs would be used on the vehicle side 7 pin connector that Mike is using for his solar panel. The Sunguard controller has a red and black wire coming out. Mike is using the vehicle side to connect to the trailer side 7 pin Bargman that Escape provides. One pin will be a ground for the black wire and other the charge battery pin for the red wire. I cannot figure out what pins to use.

You need to connect the Black wire to pin #1 and the Red wire to pin #4.

I can't tell from the diagram, is this an image of the connector on the trailer side or the vehicle side? They are reverse locations depending on which side.

Most connectors have numbers on them.
Attached is a picture from the car side which has male contact studs.

Mitigation of amateur misinterpretation was pretty good at Elk Neck St. Pk., Northeast MD. over the weekend. Clear weather Fri., Sat., Sun. The usual use of water pump, lights, range hood, roof fan and approx. 3 hrs. of TV news on inverter-powered AC television over 2-1/2 days. Resting voltage on group 27 was 12.58V when we got home. I'm going to stick with the controller on the panel. Now that I'm retired, Byron's configuration is attractive for car battery charge maintenance. Have to make up another flat connector pigtail for that. And I'll stick with the 12/3 SJ cable despite the extra conductor because it was free for the taking and appears to be producing charge maintenance and recovery adequate to my purpose.

Way to go. Watch the mail for your Jr. Electrical Engineer aka "Sparky" merit badge.

Oh definitely "sparky" in my case; forever touching a live wire of misinfo; not sufficiently grounded in the basics I fear. Or the esoterics? Or perhaps etherics?

That was a very good diagram you posted. I had the same doubts when I was hooking mine up. Once I thought I had the right ones figured out on the trailer end, I went out and tested those two with a voltmeter. Assured that I had it correct, I then marked with red and black sharpie markers the mirror-image prongs on the plug I would be wiring. Having such a good diagram would have made it simpler.

Thanks

Thanks to Mike Magee for sharing your solar setup. After reading this I went ahead and ordered the same panel and controller. They arrived yesterday and in short order I had the same power cord spliced in and had the panel charging my battery. I didn't do the 7 pin uption as I recently added this battery box Cabela's: Cabela's Battery Box and made my connection to the external battery posts.
