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?

Will look at the parameters tomorrow and see what I can change. That 120 minute timer on the boost should be changed, are you using 180 minutes?
Do you have anything running while the panels are charging? I found a drop of .6 volts which was from my fridge and parasitic stuff. Once I turned it off, the volts went up to -.1 volts below that of the controller.
I had removed a battery from the TT and set it on my porch while doing the experiment, so no other loads. I have set the timer to 180 minutes and the boost voltage to 15.
I did notice that the controller displays both panel and battery voltages, and I was looking at panel volts.That accounts for 0.1 of the difference, and now my DVM agrees with the controller measurement.
There is a fuse and an SB50 connector in the line, I'm not sure how much drop they contribute. The wire is marked as 1.5 mm2, so I think that is an area, not a diameter. I'm not sure what wire gauge that is.
I will probably re-wire with thicker wire.
