Solar Panel help - Event Date: 21 Aug 2018

Just asking:  are you connected to shore power?  I am interpreting Plug In as AC plug in like in a house.  The items you referred to (lights, bathroom fan, hitch motor) are DC and run from the battery.

Sheila R-pods have 2 seperate systems.  12 v for traveling and boondocking.

110v Shore power at campgrounds that have that available.

Charging your 12 v battery is not going to make the plug ins work.

Need to connect the big black cord to the side of the pod and plug it into 30/50 amp shore power.

Totally seperate systems. They are both electric, but different flavors for doing different things.

I also use a CPAP machine. Mine is a Respironics System One. It comes with a power block for 110V power, but actually runs on 12V. For that, I looked on Amazon and found a 12V cord for the CPAP machine. I then installed 12V power outlets in my RP179. The first one was in the panel below the bed on the same side as the furnace and water heater. I tapped into the furnace's power for that outlet. When I turned our sleeping arrangements around so that our heads were toward the door side (to better block sound from the AC unit and furnace), I installed a second outlet next to the outlet for the television, tapping into the line that powers the stereo and antenna. I also installed USB charging outlets.

I run my CPAP machine with the heater for the water tank turned off, but with water in the tank for passive humidification. That keeps the power draw lower yet still gives me some humidification. I had previously installed a shelf above the bed and my CPAP machine sits there. Depending on where your daughter sleeps, your location for a shelf and power outlet may differ. Please check my mods (see link in signature) for pictures.

If your daughter's CPAP machine will work on 12V, then look for a power cord. If it requires 24V, then I think there are 12V to 24V converters. Still though, you will need to install 12V outlets to make this work. Even if you were to use an inverter to supply 110V power, you would need to install a 12V outlet for that to work. A small 150 Watt inverter would likely be more than sufficient although it would not be as efficient as running on 12V (if machine supports it).
