Question, because I havent found a really good source on marine solar
system design. I'm stuck on a solar
system design issue.
I'm planning on installing approx 500watts of panels
between the aft davits
and the hard dodger
. I've decided fto use 5 x 100watt panels
to combat the inevitable shadowing issues with having a ketch
rig. I've spec'd out the design 2 ways
2 arrays 1 x 300watt and 1 x200watt with 1 large 40 amp MPPT
controller. this puts the combined output (with switches to isolate) at almost the max output of the controller.
2 arrays 1 x 300watt with 1 30amp MPPT
controller and 1 x200watt with 1 20 amp MPPT controller. This gives me reserver space for potentiallty adding a bit more solar if needed but increases the cost and complexity.
what is the preferred way to set this up? The panels will be flat, permanently mounted and not tracking the sun in any way. Will the Controllers conflict with each other reading the battery
