Product Overview

ARCO Marine BI-3202 Battery Isolator for 10-350A Alternators

The BI-3202 from Arco Marine is designed for use with 10 to 350-amp alternators in 12, 24, or 32-volt negative ground systems. This battery isolator allows for the integration of two alternators and two batteries while ensuring safe and efficient charging.

Key Benefits:

This solid-state device ensures electrical current flows in one direction only, preventing higher-charged batteries from discharging into lower-charged ones, thus optimizing battery health and longevity.

Note: This isolator should not be used in conjunction with 12 volt charging systems with 24 volt trolling motors or modern outboard engines equipped with rectifier-regulator systems. For any issues or concerns, please contact the manufacturer directly as returns are not accepted at the point of purchase.

Technical Specifications

  • Compatible with 2 alternators and 2 batteries, up to 120A max.
  • Safe solid-state technology that allows current to flow in one direction only.
  • Automatic charging of both batteries based on need while the engine runs.
  • Works seamlessly with selector switches without needing to change positions for charging.
  • Proportions charging output to each battery as required.
