As a result of several comments concerning solar - or lack thereof - to my thread https://sprinter-source.com/forum/showthread.php?t=54173
we revisited solar and decided now was the time to add it. Not wanting to totally reinvent the wheel, I relied on several installed, up and running systems as a basis for design. The particulars are:

we revisited solar and decided now was the time to add it. Not wanting to totally reinvent the wheel, I relied on several installed, up and running systems as a basis for design. The particulars are:
- (4) 2'x4' panels covers my available space
- The panels will run east west supported by a continuous aluminum upturned angle that may also serve as a mounting point for a future awning
- The panels will be connected in a Series/Parallel configuration
- Are my calculations correct? Never done solar or S/P circuits before.
- The 8AWG connector cable is - I believe - way over sized. In running the numbers - assuming they are correct - a wire sizing calculator showed 14 ga - even with a 2% loss. I will probably use a 10ga cable with MC4 connectors molded on.
- The isolation switch between the panels and Controller - will something as simple as a garden variety 120v/15A wall switch work. If not, what should be used?
- There needs to be a breaker/fuse between the Controller and the 12v bus. What kind of device is used here? I've come up empty on 45v/15A breakers/fuses.
- I know the panels are connected with premade cables with molded MC4 connectors and that the panels have a box with pigtails attached. What about cable management under the panels? Seems like there are lots of cables subjected to wind and water. Cable trays/ducts, bottom panels added to each panel or lots of duct tape - what works? Perhaps a duct system mounted to the inside of the support angle under the panel. Access is an issue. What have you done?
