OP with the following update. Just did our first campout with the solar system. Started Friday and come home Monday morning . Battery voltage on the low side never went below 14.3 voltage. I did run the gen one hour in the morning for Coffee, microwave, and toaster. I also did watch tv at night until 1:00AM off the main battery bank . By my trimetric meter, I did pull the bank now to 80%. However, I did see the MS controller go into PWM stage during the weekend and the trimetric was showing 100% charge before evening . I was not in full sun, but did keep the batteries in good charge. (I think.) This morning while at the dump station, while waiting for the RV in front to get done. I checked the MS control panel and I saw 19.6 amp. I was happy with that, guess I had the panels lines up with the sun good. That gave me great hopes on the solar thing. Now I need to just get the last two 120watt panels in my plan to complete it. Just got to fined more mad money to pay for them. Looks like I am hooked on to the solar train.
