Solar Kit
Just received my kit. 2 100w panels with a 30a pwm controller. Hoping it will recharge my 2 GC2's. I am alone in the trailer and power use is min. Any thoughts?

Wire them in parallel.
Is your PWM charger adjustable for voltage during bulk charge mode? If so, set it for 14.8V in bulk mode.
Mount the Charge controller as close to the batteries as possible, in the closest compartment that won't allow the controller to be exposed of off gassing while charging. 3 to 5 feet of 10 gauge wire from controller to batteries should minimize any voltage loss to 1% or less.
12 ga wire from panels to charge controller should be good for up to 20 amps of solar panel, you are currently at about 11 amps, max.
Perhaps a link to the kit that you bought, so we can see which model charge controller you got? If it's similar to the Amazon version kit, you'll want to scrap that charge controller asap and get something that is voltage adjustable in bulk charge mode to 14.8 to 15.0V for when you want to top charge, which should be daily, especially if you are dry camping for periods over 7 to 10 days in a row.
It is the Amazon kit. But I will be using the gen for 110v during the morning for coffee maker & micro and my conv is 14.8 bulk so between the morning run and evening for dinner I would think between the solar & min gen run time my batt should stay charged. I am only looking to suppliment my gen to reduce the run time not eliminate it. Thanks for the suggestions.
