I have a portable generator that I run while underway to power a few things (an ice machine, a freezer and some power outlets to charge my phone among other things). Since the alternator is providing power to the batteries While underway I always unplug the charger from the main system because I was afraid that having two power sources to the batteries might not be a good idea (I plug the power supply from the generator to the AC input on the boat, just luke I would at the marina). Am I right or could I also have the charger ON to provide more juice to the batteries? The reason I ask is because the alternator doesn't provide enough juice to replenish the batteries. After two days without going to a marina to plug in, the batteries are approaching a critical level. I'm thinking that if the charger suplied additional juice on top of what the alternator is giving that I might have more autonomy. Or would it cause a conflict or an overload to the batteries? Don't want to risk busting the alternator or the generator. Thoughts?
