I bought the kit https://solartown.com/solar-panels/renogy-200-watt-12-volt-monocrystalline-foldable-solar-suitcase/ several weeks ago and finally decided on how I wanted to connect things. I have the Aliner Expedition with the Zamp SAE "reversed polarity" connector on the side of the camper. I had read quite a bit about the need to utilize a reverse polarity adapter so bought one. However, I also recently read quite a bit about avoiding the use of the adapter and simply reversing the wires when connecting to the charge controller. As I already had to wire in MC4 connectors, a 20a inline fuse holder between the solar panels and the charge controller, and a 20a inline fuse holder between the charge controller and the batteries (not mandatory for either, but recommended), I figured avoiding another connection might be nice. As I traced the wires I couldn't understand the need to reverse the wires to correct the reverse polarity as all wires ran positive to positive and negative to negative, as they should. I even pulled the SAE connector to be sure the hot wire was red, and ran red from there. Sooo, I just commenced connecting wires (including the 30ft extension red/black cables I bought for the solar panels) as I would if reverse polarity wasn't a factor. I had given thought to where I could install the charge controller - a place that was easily viewable but protected from the elements. When looking at the Zamp SAE connector and needing to trace the wires from it, it was evident that the wires leading from the SAE connector ran inside to the storage area under the dinette seat, which gave me access from the exterior storage door as well as from inside under the dinette seat. Once I connected the wires I was receiving 1.4 amps under a cloudy sky. Once the clouds cleared it increased to 6.6 amps. Not sure if that's considered good or not but it's comforting to know I have another means to keep my batteries charged. I'll be testing things as the days go by to get an idea how long it may take to fully charge from 12.2 volts. I do have two additional 100w panels but not sure if I want to bother with them right now. I don't imagine I need them to keep the batteries charged. And THEN, I want to see if I can charge my electric bike off of the fully charged batteries.
