Hello Les and Helen,
looking at this link:
FP cpap600
They recommend a 300W/500W surge inverter, so the amp draw on a 12V battery can be expected to be around 25A max, most likely less than 20A time averaged.
So for 8 hours of sleep, that's around 160Ah.
You could try to get away with 2x95Ah batteries wired in parallel.
But 2x125Ah in parallel would definitely work.
charging:
a generator or mains powered charger up to 50 or 60A peak output.
Or, a smaller charger, say 25A output, powered by generator for 6 hours. In both cases, supplementary solar charging (100W panel) for the remainder of the day is definitely a bonus.
I'd contact the manufacturer first, to find out the more detailed power requirements of this particular unit.
Also ask, what type of inverter can be used: modified sine or pure sine.
More battery info can be found in my profile.
cheers, Peter

Les & Helen,
I'm not familiar with the F&P machine, and you didn't say whether you're using an humidifier (which will draw significantly more current).
I have a Resmed S9 Autoset, and the specs are (for my pressure setting) 0.95A without the humidifier, and 4.09A with, when using their DC converter.
Based on the literature I've read, your needs will vary with pressure and EPR settings, plus the temp you run your humidifier at (if fitted).
For
inverters, I can run my device on a 150w square wave, or 200w with the humidifier.
Jump on the F&P website. They should have the info you need there.
