OK, I've read the explanations several times and do not see how it will benefit me.
The Blue Sea document states:
"Start Isolation.
Condition: Engine Starting
-Relay is open isolating batteries
-Batteries are isolated to protect sensitive electronics from voltage sags and spikes."
If I understand this correctly it is only an advantage if you use house bank for house loads and reserve bank for starting of engine.
When using the house bank for house loads AND starting the engine the electronics will still see any voltage sag or spikes during starting.
The only advantage I see is that by isolating the batteries your ensuring the starting current is only drawn from the house bank.
Of course the batteries will only be connected by the ACR when charging with the shore charger if the engine is not running.
Is the issue with starting the engine while charging with shore power?
I'm in the middle of my DC upgrade and am ready to run a wire for the SI feature if I will benefit from it. Just don't see how I will.
I know I am missing something so appreciate someone helping me understand this.
