Well I guess I know everything I need to know, I started at 14, some 65 years ago for the EC my older brothers worked for. I spent a few years involved in the traffic signal field from an Electrical Craft Helper up to and including a District Supervisor with over 100 electricians, electrical craft helpers and laborers. My job evolved over the year from repairing and prepping traffic signal heads for installation in the field to supervising the installation, maintenance and repair of fiber optic cable communication systems.
I don't know squat about solar systems and the equipment involved in RVs.
I guess I already know all I need to know about solar. The sun shines, the panels collect the energy and the wires transmit it to the batteries.
By the way I'm 79 years old and I have been retired for 24+ years, longer than most of you have been members or even smart allecks.
I'll just seek some pros for help.
