The purpose of the bypass switch.
Scenario.
You are not on shore power. There is no sun for solar. You want to charge the house batteries. The dc to DC renogy fails.
So use the bypass switch to do some charging.
Other advice:
Once you have the dc to DC installed, use a DC clamp on ammeter to check the current. If it is more than 50 amps, pull the "jumper" out of the renogy to limit it to 20 amps.
Input of the dc to DC can be 50% more than the output. So 40 amps out may equal 60 amps in. My opinion is that is far too much for a 124 amp alternator--unless the duty rating is 100% (they rarely are).
