2009 Lance 830 Solar wires????

I have a Lance 830 and have installed solar on it, another TC and several boats. I did mine a little differently. 2 batteries, 2 panels, 2 controllers, and a battery switch. I used 2 pwm controllers, partly for cost considerations and partly because of panel size. That aside, I used the blue wire you found for one panel and installed another larger wire and plug for the second panel. I found good access for wiring in a second location behind the pantry. I have had it for 2 years like this with good results and we go out for months. We are very frugal, LEDs etc, and trying like heck to avoid cold weather and we can easily go a week, (100 watts) with sun,before needing the genset. I am preparing to add a third panel to extend our time without the genset. With our setup, if either side fails I can combine or separate the batteries and use just one panel or battery. I actually had a panel destroyed on one of my boats. This is much more simplistic than many others but I learned a long time ago, plan for the worst. I do think mppt controllers are great, and more efficient, but not for me. Fwiw I would not use just one 12 gauge wire for 200 watts. I am picture challenged here but if you pm me your email I will send you pictures. Chris By the way, and I know many will not agree, but here goes. Inverters are not our friends. Except for some small electronics, for which we carry a 100 watt inverter we are completely 12 volt, and yes, we have a tv and DVD player. Obviously for the charger and ac, if you want them, you need power, not an invertor.
