off grid camping

Have 2016 Rockwood Mini Lite and want to do some off grid camping. Will need to run a CPAP machine at night which will draw down our battery. Would a solar cell charging system be able to recharge our battery or should I go with a portable generator? My Mini is prewired fora Zamp Solar charging system. Thanks for any and all responses.

You'll get quicker more efficient recharge times with a small 2000 Honda

I have a Wolf Pack 5th wheel. I also use a CPAP on 12 volts I have 3-12v batteries. I have to run the generator in the about an hour in the morning and then about an hour before I go to sleep, or I could have problem getting the gen started in the morning. Don't have solar power.

My suggestion is you should go for both. It does not take a big generator to charge just batteries.

You really need to also look at the requirements of your cpap and make sure it will continue to operate properly if you have to use an inverter. Most cpap manufacturers have these requirements available.

I would get a Honda eu2000 and let it run all night. Just get an extension cord to move it some away from the camper. They are so quiet anyway. Then there would never be a problem.

You can figure about 8 amps at 12 v DC for the CPAP. Or use a small inverter.

Your CPAP will use between 20-30 amp hours of battery in a 8 hour period depending on the setting. 200 watts of solar will deliver on average (with no shade) about 60 amp hours of recharge per day. If you have a single deep cycle battery rated at 120 ah, you would not have a problem running your CPAP using solar.
