Roll Up Solar Panels / Ogre MPPT Controller
I would LOVE to get 10-12 amperes of 12 volt grade charging for my new group 31 Lifeline. But I have a motor-scooter size toad, that forces me to the roll-up kind of solar panel, and woe is me, the...

Here is my plan haffassed as it is: With a roof rack I can carry some things. But the car ain't no Kenworth or Dodge diesel. It has 1,100 lb capacity tires, and a ONE core radiator. I need to keep things light and panels are heavier than skunk anger. The object is to feed a single group 31 AGM enough kWh to power the BiPAP, some LED lights and a fantastic fan for a couple of days (fan mostly, lights four hours, BiPAP maybe seven hours. Call it fifty amp hours a night).
Panels will go flat on the roof of my rig. All flat no shadows. I have enough 6 gauge wire to run from the controller to the battery, forty-five feet distant. The battery has to be kept in the bedroom of the house. The rig gets too hot during the day (a patch of sunlight travels across the rig rear to front and by 1800 hours it's 38C inside. 28C inside the concrete bedroom. Going to chop a parota tree to get the panels more light and use the beautiful red parota hardwood for my evil designs after it dries out. This means digging a channel from the rig to the house and stuffing the wire in plastic conduit. I have two 51 watt Kyocera panels atop the rig doing their thing, with the battery. So the new panel's setting will remain vandal resistant. SDS drilling through 8" of concrete will be Jesus's job.
I use the toad to run around south southern California when I am up there for medical. But Mexican Customs is nightmare incorporated for taxing solar panels. If I can stack multiple layers of unrolled panels inside the roof rack then I might be able to pull a fast one. Panels down here cost about 400% of those in the states.
