Solar advice

I have been dry camping for over 11 years and used a VOM plugged into the cigarette lighter plug to let me know the voltage. Using the voltage chart from Trojan that let me know battery state. I just put 448watts of solar up with a Morningstar TS 45 PWM controller and to monitor it I installed the Trimetric 2030rv meter. Its less expensive than the Xantrax but tells me a whole lot more. First I found out how frugal we have been all these years, second it showed me how long it took to recharge. The person who said they could get 20 amps out of one panel is unlikely, but size up your rig and use cardboard to figure out placement and place as many panels as you can. If space is limited buy the highest wattage panels you can. In Oregon you are sun challenged so you will not get the rated output due to sun angle so you need as many watts as you can put up there. In Alaska the sun angle will only produce 40% of wattage. In San Diego its 180% of wattage. Also don't forget the tv and iphone charge is nothing compared to the water pump or turning a fan on overnight. The water pump is a battery killer, but you might just go to the bathhouses and avoid that.
