I have finally finished acquiring all of the bits to add solar charging capability to our Aliner Pop-Up trailer. Just brought home the new energy bank, a pair of Exide Deep Cycle Marine Group 31's (115 Amp-hour claimed capacity each). Did a quick setup to assure all is operational before relocating the new batteries to inside the trailer. (I will be removing the original Group 27 Dual Purpose battery forward of the propane tank.) Sunny North Texas mid-day sun had the Renogy 200 Watt suitcase system producing ~170 Watts, so all seems well so far. I would have been happy with anything over 150. I am going to keep the panels and controller in the suitcase configuration to allow positioning for best power generation and to remotely position them when setup in shady spots. I have a pair of 8 gauge, 25 foot extension cables for that purpose. If setup in a sunny area, I will likely set the panels on the roof of the dormer on the right in the photo of the Aliner. The Aliner Classic came with a "Zamp Ready" SAE 12 Volt connector on left side, forward, so I have also made a cable to match the (odd) Zamp reverse polarity standard. I'm looking forward to doing the install this weekend and having it ready for Fall camping season!
