Amp hours
I'm trying to determine whether my current solar system is adequate or if I need to add more panels/batteries. Currently I have 2 6 volt lead acid batteries. I have 300 watts of panels 40 amp con...

So I can help a little here. I had 2-6v GC batteries and 300w of solar for four years prior to my last upgrade to 4-6v GC batteries and 450w of solar. Assuming your 300w of solar is a poorly designed(yes I did say that)setup that has the controller somewhere in the living space of the coach and the batteries are solid, the only difference between what we do is the TV and Video stuff your kids are doing. I'd start by a Mr. Heater Buddy or Big Buddy to heat up the coach prior nigh, night(meme's), then turn it off. Then set your thermostat down to 55 degrees and blanket up. And as everyone has said, the furnace is the big draw, like 7-8 amps. The less it works the better you are. The Buddy will heat the coach up PDQ in the A.M. And usually you'll have the stove on making coffee that will heat up the coach too. Is the best way to know all this stuff to track it with an actual audit and a battery monitor....yes. Have I gotten that far? No. Will I? Yes, some day. Right now, trial and error, reading forums, then applying this knowledge to upgrading my solar and battery bank has made a huge difference in my boondocking comfort. We went to the Mojave desert and spent a week in the snow and the night temps were in the mid twenty's. Days were like 36 degrees. Holds up perfectly now with no generator. I would really do some reading about what a solid Solar System would look like and start there. The controller in the pass thru as close to the battery as possible is prolly the single most profitable thing you can do for your system.
