Solar charge controller selection help needed
I am looking to put in a solar system that will produce about 30 amps per day. I choose a semi-flexible 135 watt panel made by Sunpower which meets my capacity needs. My only problem is choosing t...

skripo,
You need to use fuses. #10 wire for the five foot run and #8 for the charge controller to the battery. Larger will result in lower voltage drop.
There is NO advantage to using the load outputs on the charge controller. If you ever exceed 20 amps it will burn out the controller. There is already wire from the battery bank to the DC distribution panel. There is already wire from the 55 amp converter (yes this is RV speak, the really really name is inverter from 120 vac to xx.x volts dc) to the battery bank.
How many watts of panels do you plan on installing?
How many amp-hours is the battery bank?
Are you a weekender or a full time RV person?
