My new Winnebago Mini Travel Trailer 1808 FSB says it is "Solar Ready." So there is what looks like a SAE Zamp plug-in port on the side of the trailer. My question is twofold.
1. Is there a charge controller somewhere between that plug in and the batteries? Or is an external charge controller required?
2. If it is a Zamp plug-in, is it "reverse polarity" from normal panels such as Renology, which I consider a better buy than the expensive Zamp systems.
Thank you for that. So, to be clear, one of those panels with its own charge controller built in would be what I would want, and I would have to reverse the leads coming from the solar panel to match the Zamp input port.
I have the Renogy 100 watt Portable Suitcase for my t/trailer. Essentially plug-n-play, well constructed, nicely padded case included, and does a great job keeping my dual lead-acid batteries charged when boondocking. Buy the longest extension cables available when purchasing. This allows for greater flexibility when placing your panels around the rig.
I purchased the portable solar suitcase directly from Renogy.com. My t/trailer is a 2016 model year and not “solar ready”, therefore I had no need for the Zamp adapter. At an RV show, I saw Zamp products on display and the adapter was available through them (Zamp).
Most of the panels are just 10 ga wire. When I installed mine I cut those fancy ends off. I crimped and solder in wire connectors and covered with marine grade shrink tubing. Doing it this way I could cut the wire to the length needed. I went an additional step and put the wires in metal conduit to protect them from the Arizona sun.
