ProMariner Battery Isolator

Overview

Battery isolator designed to charge multiple battery banks from a single DC source while keeping banks separate. Supports 6, 12, 24 and 32-volt negative-ground systems with up to 130A capacity.

Key Features

• Up to 130 amps maximum alternator rating
• Operates on 6, 12, 24 & 32 volt negative-ground systems
• Allows one or two devices to charge multiple battery banks without banks being connected (model dependent)
• Current flows in one direction only to prevent backfeeding
• Includes a voltage drop of approximately 0.6V across the isolator

Compatible Applications

• Marine electrical systems with multiple battery banks
• RVs, campers, and off-grid applications needing isolated charging
• Vehicles or equipment with 632V negative-ground electrical systems

Product Details

• Rated for 130 amps maximum alternator
• Operates on 6, 12, 24 & 32 volt negative ground systems
• Electrical current able to flow from DC source to batteries in one direction only
• Allows 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

Parts Desk Insights

Best Use Case: Ideal for boats or RVs that need to isolate battery banks while charging from a single alternator; supports 12 devices depending on model.

Common Issues: All isolators introduce a voltage drop (~0.6V). If charging seems reduced, account for the drop in system design. Ensure the chosen model matches the desired number of devices to be charged.
