Basic Parts List
This installation was completed in November of 2021. The owners of this travel trailer were looking for a way to keep the trailer batteries charged while in storage and to allow them to use the batteries for longer periods while boondocking before they had to use a generator to recharge them. After discussing their needs, I put together a plan and an estimate for the implementation of that plan. The customers accepted the plan and we scheduled an installation appointment. These customers were in no hurry to use the trailer so they left it with me to work on as I had time. I was able to complete the installation fairly quickly due to the basic nature of the job. The panels were mounted on the roof, near the front of the trailer. I penetrated the roof near the front cap of the trailer and brought the solar wiring down into a cabinet in the bedroom. I then fished the wires from the cabinet, through the front cap and into the pass through storage area under the bedroom. I was not able to continue the wires down through the cabinet because it did not continue all the way to the floor. It took a bit of extra work to fish the wires through the front cap, but the end result was much cleaner because no wires were visible in the living area of the trailer. The solar controller and circuit protection were mounted to the front wall of the pass through storage next to the OEM battery cutoff switch and leveling system panel. The output of the solar controller was wired directly to the batteries on the A-frame of the trailer. The customers may eventually upgrade batteries, install battery monitoring and possibly an inverter, but for now the simple solar charging is enough to meet their needs.
