Diode Bridge
Hopefully this won't leave me stranded in the wilderness lol. Two diodes tie together the inputs from the solar and alternator to monitor voltage minus diode drop on the XY 60.
When either the alternator or solar panels are producing over 13.8 volts minus 6/10 volt diode drop the alternator and starting batteries will be connected to the accessory batteries and the solar on highest leg. When the voltage drops below 13.1 volts on the highest leg, they will be disconnected.
This way the two alternator will charge the accessory batteries when the truck is running and the solar panels will maintain the starting batteries when the sun is shinning. The diodes are necessary to avoid the two systems from back feeding each other on the monitoring input.
