NewMar Battery Isolator (MPN: 1-3-165)

Efficiently manage multiple battery banks with automatic charging and isolation.

The NewMar Battery Isolator is designed to facilitate the automatic charging of multiple battery banks from a single source while ensuring complete isolation during discharge. This device employs a voltage comparator circuit and a low resistance contactor, functioning as a smart switch that connects independent battery banks only when a charging voltage is detected. This innovative design eliminates the need for diodes, thereby preventing any voltage drop and ensuring optimal charging efficiency.

With a capacity of 165 amperes, the isolator is suitable for use in 12 to 48 volt negative ground systems. It allows each battery to be charged according to its specific needs, preventing overcharging and enhancing the longevity of the batteries. The heavy-duty construction of the isolator ensures reliable performance, making it an essential component for managing multiple battery systems effectively.

This battery isolator is particularly useful in applications where multiple battery banks are required, such as in marine, RV, or off-grid solar systems. By maintaining 100 percent isolation at all times, it prevents discharge from one battery bank to another, ensuring that each bank operates independently and efficiently.
