Can this unit charge a cranking battery and a house batter on a boat?
Yes, the charger can charge both a starting battery and a house battery if the two batteries are connected through a battery isolator, Automatic Charging Relay (ACR), or a battery selector switch. In this setup, the solar charger will maintain both batteries.
If the starting battery and house battery are completely separate and not connected by a battery management system, the charger can only charge one battery at a time.
