I am wanting to put together a system that will be primarily used for camping, but will also be a backup system at home in the event of power outages. I am considering solar for the ability to go beyond a set number of days of use. However, determining how much panel I would need has become an exercise in discovering my limitations in science and math. Hoping for some assistance.
I do not have the manual for the CPAP, but here is the power info from the bottom of the machine: 100-240V ~ 50/60Hz 12 V (A long line with 3 beneath it). AC 1.0 A Max. DC 3.0 A Max.
I am looking at using 2 18AH SLA batteries for size and cost if acceptable in this application. Batteries
It will be run approximately 8 hours per night. The only thing being run on this is the CPAP machine. No humidifier, lights, charging phones, etc., purely a CPAP power system.
I have considered a massive marine deep cycle battery and an inverter, but I would like something smaller, lighter, and usable in all situations if it makes sense to do it that way. I do have the DC setup and have used it off a small jump box in the past, but I could only get a night and a half out of that. If I understand the basics of amp hours correctly, using an inverter uses less power?
Thanks for any help.
