I could can get the 200w to start our solar system than I can for the battery. I would still need some type of power to recharge the battery. Thanks for the heads up for turning off the humidifier. I will have to ask my DME if they have a loaner battery.
OK. Cpap. Get one that runs 12 v. I have had three different ones all had an external power supply and the output was rated 12 -14 v and 3 or 4 amps with humidifier that probably accounts for half the amperage. Otherwise we are all led and have frig with switch that turns off the door frame warmer. All of my machines had factory cig lighter plug cords available and operation was no different than off 120v power supply.
200 watts solar meets our needs with three 70-80 amp group 24 batteries. We run small 12v TV for hours daily and 200 watt HF cheapy inverter for direct TV box with a manual Sat dish.
For the new TH on order now it comes with 200 watts solar and we will start with two interstate GC2 6 v batts from Costco at $85 each.
That will be for starters. More may come.
My solar dealer is WindyNation.com. Renogy might be a tad better output if you believe YouTube but it is a tad more expensive at the same time. The new TH has
A GoPower controller that looks good according to the specs I have found. Better be good. Mya buddy had that done as an after production factory add on at. $1500 for 160 watts. He charges two huge AGM oversized $350 6v batts and is very happy.
