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?

Ran a test today. Drained house batteries down 20 amps. Kept fridge running on propane. With fridge going and parasitic drain the draw is .6amps. Connected panels and end of day there was still 5.0 amps down. Panels went into float with .2amps charging at 13.2 volts.
I disconnected panels and started generator. When it settled in it was charging 5.0amps at 14.2 volts. Ran the generator for 20 minutes and the battery monitor showed 3.7 amps down.
So the panels are shutting down too soon before the batteries are fully topped off. The max voltage I saw on the controller was 14.4 volts.
Something I didn't consider was the basic draw of the fridge etc from the panels output. Thus max output of 5.8 gives me only 5.2 amps charging.
Tried to change charging perameters but didn't work. Hope Solar 30 controller will work better.
