I am planing to set 2 Orions 30A dc/dc in parallel, to be fed with 2 70A Alternators each. I have 2 alternators already in my engine, so I need 2 orions to have an input of 60A, to my new LiFePo big bank.
I have a isolator between orions and alternators. The two Orions are feeding (out) to 800Ah LifePo bank, and there is a AGM 230Ah battery bank (bow battery) in their in (out of the islolator and in of the orions).. That's means both alternators are giving power to the 2 isolator outputs, one will be conected to both Orions, the other, to the crank batery.
So any alternator is giving power to either the crank batery or the bow battery, and with this last, both alternators are giving power to the 2 orions.
I wonder what would happen if one of the alternators could fail, so the scenario could led to have the surviving alternator of 70A, connected to 2 Orions, each one demanding at maximun 30A, plus the crank battery of course. Could this situation led to a breakdown of the remaining alternator, as both orions are demanding almost the 30A , plus crank battery, almost the maximum 70A?
thanks a lot
