Key Features

Intelligent Alternator Power Distribution

The ProIsoCharge130 2x4 intelligently manages your engine's alternator output, ensuring optimal distribution of power across multiple battery banks. This smart system eliminates voltage loss, allowing you to charge up to three additional battery banks from a single alternator (model-specific). For boats with dual engines, our exclusive model accommodates inputs from two alternators and supports up to four battery banks.

ProMar Digital Performance

Experience superior battery health with ProMar Digital Performance technology. This feature actively monitors and prioritizes the charging of your engine start batteries while distributing full alternator output to other battery banks. The result is enhanced battery longevity and performance, ensuring your boat is always ready for your next adventure.

Advanced Software Control

Our intelligent software prioritizes charging for battery banks that are under load, such as your house bank or power inverter bank. Fully charged batteries are automatically taken offline, allowing discharged banks to receive priority charging. This ensures that your engine batteries remain healthy and your auxiliary systems are always powered.

Real-Time LED Status Indicators

Stay informed with highly visible LED indicators that display alternator power presence and battery bank charging status. Fault indicators alert you to issues such as high or low alternator output, over-voltage protection, and high voltage conditions on any connected battery banks. This real-time monitoring helps maintain the reliability of your boat's electrical system.

Ignition Controlled Operation

The ProIsoCharge130 2x4 features ignition-controlled battery bank management, activating only when ignition power is on. This ensures that your electrical system operates efficiently, conserving energy when your boat is not in use.

Advanced Regulator Compatibility

Designed for precision, the ProIsoCharge130 2x4 includes a remote sense connection for advanced regulator control. This ensures seamless integration with alternators equipped with advanced regulators, optimizing charging performance and battery health.

Easy Installation

Featuring a modular design, the ProIsoCharge130 2x4 is straightforward to install. It includes all necessary terminal stud insulator boots and a protective snap-on safety cover, simplifying the setup process and ensuring a secure, professional installation.

Built-in Safety Features

Safety is paramount with the ProIsoCharge130 2x4. It is ignition protected and boasts an IP66 waterproof rating, making it resilient against harsh marine environments. Additionally, the system is backed by a five-year warranty, providing peace of mind for your investment.
