First, let me thank everyone for their comments. I find this site, compared to others, offers more advise and less criticism. My setup is off grid and a one weekend a month visit. This time of the year, hunting season, is every weekend for 6-7 weeks. I have a setup that most would say, will not work, but it has been working for 5 years. 10 (ten) 12 volt AGM batteries in parallel. 200 watts total solar. This past weekend, 3 days in total of 4000 watt hours used.
Next, I'm a scrounger. I pay full price for very little. If you have the time and connections, you can find almost anything. My batteries, Inverter, charge controller were free. I had to pay for the panels, close to $4 a watt at the time.
My system has been working fine, but, times are changing. I now use more power after we go to sleep. Up to 5 CPAP machines.
So, maybe I will stick with 12 volts and just add more solar. Cheap 30 volt panels and a MTTP controller, or 12 volt panels and a 12 volt controller? And a good backup generator.
