My sailboat currently has 4 batteries in 2 banks of type 27 batteries. The system is running 12v. The boat has a battery switch "1 both 2 and off". It currently doesn't have a separate starter battery, but I want to install one of the type27 batteries as the starter battery.
I have a new running mttp 100/50 and two 330w panels charging 3 parallel 4D AGM batteries that are mounted and charging, but not connected to the system that will be my house batteries.
I'm looking for a schematic that I can use to properly install the system. New battery switches and isolator with a battery monitor.
Is there a schematic available to follow?
