Isolators allow you to charge batteries automatically from one or two alternators, and prevent discharge from one battery into another. Each battery is charged according to its need without overcharging. These isolators are rated for 12-32 Volts.
Promariner battery isolators operate on 6, 12, 24 & 32 Volt negative ground systems. Electrical current is able to flow from DC source to batteries in one direction only. They allow one or two devices (depending on isolation model) to charge multiple battery banks without the banks being connected. NOTE: All isolators impose a .6 volt drop in the circuit.
