Routing Solar Wires Through Fridge Vent
Hi all! I am thinking about installing a solar system on my 2012 Jayco X19H. Have been reading a lot in the last few days, and I think that I would like to run the wiring through the Fridge Vent. ...

Thanks BFL13!
One thing is that with the PWM controller, you could not wire the panels in series, and therefore reducing the current that needs to be wired to the controller, right? Does the PWM controller support trickle charging / battery maintaining?
With a 12v battery system the array must be 12v too with PWM. A PWM can do two 12v panels is series if it is a "12/24" controller, but then the battery bank must also be 24v.
PWM or MPPT controllers can do battery maintaining etc IF they have adjustable voltage for their "stages" and some even have timers. Plain Jane PWMs that cost $25 usually don't have adjustable voltages. Some like my Solar30 PWM has adjustable voltage, no timer.
But even the nice Tracer MPPT which is lower cost than many MPPTs has a fixed charging profile. You can get the extra gizmo for it (a remote) that has a way so you can make adjustments. The latest thing seems to be where some let you adjust their parameters using your cell phone!
