Smketter ... thanks for that. I think I'm sort of, kind of, starting to understand ... a little. I've been pondering the Bogart 2030 (?) units for the PWM charge controller and battery monitor (sorry, on cellphone and don't have part #'s) since they talk to each other which is nice.
Just so much info out there and lots of people disagree on what's best for this or that. It's hard to find my way through the forest sometimes.
The Bogart system works really well. My first Bogart system (TM 2030 battery monitor and the SC2030 and related parts) was 200 watts on my MH and the plan was to add panels over time.(adding panels on a MPPT controller over time can easily negate any charge advantage. Do your homework) We bought a trailer and I get to start over. This time I will start with 4 160 watt panels flat on the roof using the Bogart system. Why? Its simple when cloudy,rainy weather I will still get enough power to take care of my needs. And as far as adding panels beyond a good controllers ability, An 8$ adjustable voltage/timer can take care of that chore for bulk.
