I recently purchased a Renogy 100 watt solar panel through Amazon to provide a non-generator power source for dry camping. We love the Yamaha 2400iSHC for running the air conditioner or whatever else we need, but generators aren't the greatest way to recharge batteries if you're using a smart charger (which you should be).
The reason for this is after your batteries reach about 80% state-of-charge (SOC), your smart charger begins stepping down the amperage flowing to the batteries. This is both for battery health and to minimize the use of unnecessary electrical power (for reasons beyond the scope of this post). Since the minimum output that a generator like mine can provide is about 500 watts (1/4 of its continuous rated output), that's about 40 amps of 12 volt current. That's way too much current for recharging batteries for the Pod, and the electrical power that doesn't go into the batteries or get used elsewhere is wasted.
However, a solar panel with a smart charge controller (NEVER use a solar trickle charger with a solar panel rated above 15 watts; it will eventually and literally cook your batteries) will do a great job of recharging your batteries from a solar panel. It will step down the current flowing to the batteries as the batteries are recharged, the way it should.
So enough about the technical stuff. Here are the pictures!
This is my Renogy 100 watt solar panel from Amazon. They're $149.99 and get outstanding reviews. They produce solar power significantly better than older panels and are designed for outdoor use already. I made a little stand for it out of PVC pipe and connectors. I attached the panel to the stand with heavy duty zip ties running through holes drilled through the PVC. I didn't glue in anything yet because I wanted the setup to be flexible. To adjust the tilt of the panel, I just twist the two pipes at the back.
This is a 10 amp Sunforce solar charge controller. It adjusts the current flowing to the batteries depending on their SOC. I screwed it into the back wall of the exterior storage so it wouldn't get bumped around.
The MC4 connectors provided with the solar panel are only about 18 inches long, far too short to adjust the panel appropriately, and getting extensions are expensive. So I got a 15 foot 12 gauge extension cord so I can move the panel to either side of the Pod easily. Getting a 12 gauge cord is necessary to handle the current coming from the panel. I cut off the ends of the extension cord and connected to the MC4 connectors on the solar panel and the charge controller with wire nut connectors which I then wrapped heavily with electrical tape and two zip ties so they won't be pulled apart. Where the extension cord comes up to the charge controller, I attached the cord to the back wall with zip ties and screws so it won't pull on the charge controller.
I connect the charge controller to the Zamp port with a Battery Tender ring terminal harness. This already has an inline fuse holder that a 10 amp automotive fuse can be placed into.
If you have a Pod that doesn't have the Zamp port, you could run 16 gauge (yes, it's sufficient for the amperage and distance) wire under the Pod up to the batteries without much difficulty. But the Zamp port makes this very easy.
