Can I Connect Two Alternators to One Battery Isolator?


Hi Jeff, love your videos. I purchased your recommended Victron battery isolator(3 outputs). My boat has two engines with one alternator each. Can I connect both alternators to the one battery Isolator?  Thanks.  -  Neil


Since you have two engines, each with its own alternator, you’ll need two battery isolators, one for each alternator. Remember that most battery isolators have only one input and multiple outputs (2 to 3 depending on the model). You can have each battery isolator connect to the house battery too.
