Beth uses a CPAP. We don't have an inverter, just the 2x6v batteries and the stock Escape solar panel. She uses it in the trailer with the humidity control. I was fortunate to get a 12v-24v converter for the CPAP machine and there's both 120v AC and 12v DC plugs at the foot of bed on her side.
Between using lights, likely the TV (120v with small plug in inverter) for some hours in the evening, then the CPAP all night the batteries are still quite well charged come morning. Using an inverter for your CPAP would likely draw down the batteries more since it's less efficient turning the DC to AC back to DC than our converting the DC 12-24.
Check into getting a converter for your CPAP.
