Solar Backup for CPAP Machine.
Hey guys (and gals). First time poster, I depend on a CPAP machine to breathe correctly while I sleep as I have obstructive sleep apnea. I am a avid outdoors person and would like a way to run my machine while on camping trips with no A/C power at the site. I would also like piece of mind in the event of a hurricane where power may be out for days. My unit only draws about 15 watts when i leave the humidity heater plate off. It requires A/C power. I currently have it plugged into a APC Smart700 sinewave UPS. Upon testing the UPS runs my machine for about 6 hours before konking out so its not a viable solution (Its a 5yr old UPS). My insurance company will re-imburse me up to $250 dollars for supplies for an emergency backup power source (Including solar applications) I am willing to put in up to 250 of my own money if i can come up with a portable solar solution. Any suggestions or more info needed to help me find a solution. (BTW Im somewhat versed in the field of electronics/ amps/ watts, ect, but not much on solar power systms)
