I want to charge a deep cycle battery with a solar charge controller and dual battery isolator powered by the car alternator. The dual battery isolator will provide the most charging power when driving and the solar will help to keep the battery topped up when camping.
As I am feeding two power sources into one battery do I need diode oring to avoid damaging the two different chargers?
Below is a the wiring diagram of a 12V system. The Dual Battery Isolator will provide up to 120A and solar up to 10A. So I thought I put strong Schottky diodes in protect each charger.
