ZAMP wiring

There are a few variables, but stranded copper 10g wire will lose about .25 volts every 15 feet. Your controller may have an adjustable output, or automatic.

That calculator is really cool. Makes it easy for the rookie/amateur (me) to get a fast answer. Looks like if I use 10 gauge cable I can go about 35' from the Zamp port and keep the line loss to less than 3%. Solar chargers can be a challenge when you want the trailer in the shade, but the solar panel needs to be in the sun. Thanks for the link.

LOL, Good Deal...don't forget to add the original 20' or so if you are using the Zamp Plug! 

oooops, I mean total distance of 50'. 20' plus 30', uh, somebody help me here...I ran out of fingers and toes.

Originally posted by shanebevel As a weird side note, the first thing I thought when I saw the port was power access! The plug used (while not the awesome Anderson Power Pole) is a standard connector, so a man could build a pigtail to whatever he wanted and access 12v from the back of the camper through a sizable cable. Ham radio/chargers/12v led lantern all kinds of stuff.  My only thought was that I didn't know if it ran through a converter of some type, but it looks like a direct connection, so that's pretty cool! So in theory, any solar panel producing 12v+ could be used here right? Not just a zamp branded kit.  Shane

Yes you can add a SAE connector to any panel/controller combo and feed at that port.. and yes.. 12v goes both ways.. so you could add a properly wired SAE connector to anything 12v you wanted to power outside.
