A friend of mine (Yes, I have one) is buying prebuilt shed and put it in the woods. She wants to be able to run her CPAP machine for a night or two at most every weekend, or so. What does she need as far as solar panel power? How big of a battery? Howbig of an inverter? TIA

Hey, I have some recent experience with this. I use this battery for my wife's machine.goes into her machine. If you search Amazon you can probably find dc inverters that will plug straight into her machine from her dc power source. That's where I found the one I'm using for my wife's ResMed machine.

This will run her machine all night with a little left over. The inverter I use plugs straight into her machine where the ac transformer normally plugs in. That way I don't get any power loss from converting dc to ac and back to dc when it actually
If she has room in her vehicle her best bet would probably be to install an isolated battery deep cycle battery in her vehicle and use that to power her CPAP.Update...I told her what she was going to need. Before I told her the type, size, and such, whe went to a place called Harbor freight and the guy there told her what she needed and and she bought the 100 watt kit and all the other pieces (one stop shop).
To have any idea what size solar panels she would need you need to know how much power her machine needs. It would help to know what machine she is using. The power specifications would be useful if she has them.

Your friend wants this shed placed in the woods you might want to tell him solar panels need sunlight to function, he might want to choose a wind generator instead they produce significant more power than solar that are only about 80% efficient at thebest of time. We have a 5 KW air turbine to run the entire house that includes 2 AC units, and being by the ocean with a nice breeze we average about 100 Kw per day that’s fed into the grid and provides more than enough, all he would need is more the

the type, size, and such, whe went to a place called Harbor freight
and the guy there told her what she needed and and she bought the
100 watt kit and all the other pieces (one stop shop). It had 4
panels, controller, Battery, 2000 watt inverter. It came with
everything except the power wire to the inverter which I made one
up for her so we could test it. It was very easy and worked very
well. It supplied her cpap all the time she slept, which was only 6
hours. The battery voltage dropped from 13.0 to 12.6. I felt the
items she had bought would be sufficient to do what she wanted to
do. I then made a harness which included a fuse and polarized plugs
so she or her daughter wouldn't be able to hook up backyards. I
told her to try different things and keep an eye on the voltage so
to determine the limits of the unit. She called me back about 10
minutes later to tell me it wasn't working. I went over and found
she blew the fuse (whew). After asking what did, she said she
plugged in a toaster! The fuse was only 5 amp. LOL. Changed the
fuse to a 10 amp but told her not to use anything like a toaster of
hair dryer, and buy a few extra fuses. She and her daughter will be
testing it out this weekend. Wish ME luck. LOL

There is usually a very good reason for the size of the fuse, and solving the problem with replacing it with something larger inevitably creates a fire hazard and or over heating of wiring.
