Solar setup input?
Hello! Thanks for all of your input; reading through these forums helps a lot. We got a '95 Winnebago Adventurer that already had a 400W system installed - 4 100W panels wired up to a PWM controll...

20A, 12awg, voltage drop is .326v per 5' (1-way circuit length)
20A, 10awg, voltage drop is .205v per 5'
PWM < 1v drop between the panels and controller
nill between the controller and batteries or battery voltage sensor.
mppt would let you series all 4 or sets of 2, reducing current/voltage drop.
mppt, voltage drop from panels to controller = loss power.
nill between the controller and batteries or battery voltage sensor.
controller with bluetooth and phone app would let you monitor system and adjust set pts/time from the campfire!
