In the California Channel Islands, fairly far off the grid, solar power has been in use for more than thirty years. As a user during this time, I am completely satisfied. Incredibly less time devoted to maintenance and I am fairly confident that energy costs are less as well.

If your situation is favorable, consider adding wind generation as well. The type of turbine found on sailing vessels works well with a small solar setup....

Thanks for the comments and suggestions.

CPAP's are one of the joys of getting older.

My model is a Respironics PR System One REMstar 60 Series Plus with humidifier (http://www.thecpapshop.com/respironics-pr-system-one-60-series-plus-with-humidifier-tube). I use 11cm (it goes up to 20), so it'd probably be less than the 5A listed on the device, and even less without the humidifier.

I'm an occasional hunter & camper, but use an old trailer or tent without internal batteries, so would be able to carry the weight of batteries. For short term home use, I could use a generator, but that would quickly use up fuel supplies, at night, and possibly attract unwanted attention, if the wrong scenario played out.

I am looking into this device as a non-CPAP option http://www.glidewelldental.com/dentist/services/removables-silent-nite.aspx. With the cost of going to batteries, that device may be a better option.

Thanks.

I realise I'm replying to a old post but in the hospital we use disposable PEEP valves attached to our ambu bags when performing cpr. I would assume your could rig up one of these valves with your cpap mask.

In this study they tried a similar setup, seems like it worked for some:

I kept searching and found the Freedom CPAP Battery Kit. (
https://www.cpapdirect.com/parts-and-accessories/battery-power-solutions-freedom-cpap-battery-kit )

I got an extra battery for a backup, or to run in series, and a cigarette plug adapter. With USB ports, I can charge a phone or handy-talky radio.

They also have the option of a solar charger. http://www.batterypowersolutions.net/product/sunpower-solar-panel

The two batteries will have to do for now, but the solar panel is on the list for next year's Flex Spending card, if enough's left.

Thanks, again, for the input.

I took an old tool box, bolted an 1500 watt inverter on the lid, and put three 35 amp hour agm batteries in the box, cabled in parallel. The combination will run my cpap and a floor fan all night, and recharges off the grid or the generator. Total cost in $400 range. Heavy, but I found a folding dolly for $15 that handles it nicely.

Excellent improvisation Nursemike! Are you using deep cycle batteries? What sort of life (if you will) are you getting out of the batteries?
