• Maintain: Keeps your batteries in peak condition during extended periods of use.
• Re-condition: Revitalizes batteries by removing sulfation and restoring capacity.
• Automatic Dockside Power Mode: Seamlessly switches to power 12V DC lighting and appliances.
• Battery Type Selection: Factory set for Flooded (Lead Acid) batteries with selectable AGM and GEL options.

Power Factor Correction & Global AC Input

Featuring auto-ranging capability, the ProNauticP accepts a wide range of AC inputs (100-250VAC/50-60Hz), making it suitable for global use. Its power factor correction reduces harmonic distortion, allowing the charger to operate efficiently from a standard household power outlet while conserving onboard AC power.

Distributed On Demand Technology

ProNauticP intelligently monitors and distributes 100% of available charging amps to any single bank or a combination of all banks based on demand, ensuring your batteries receive the power they need when they need it.

Intelligent Charging Modes

Digital Self-Calculating Absorption

The charger automatically adjusts conditioning time based on the battery's discharge state, ensuring optimal charging without manual intervention.

Battery Health Re-Conditioning Mode

After 21 days in maintain mode, the system automatically de-sulfates batteries, improving reserve power performance and extending overall battery life.

Conservation Energy Saver Mode

In the absence of a significant load (less than 5 amps) for 72 hours, the float voltage is lowered to conserve energy during storage periods. This feature is available for both flooded and sealed charge profiles.

Service and Fault Mode Indicators

Dual digital displays provide real-time information on charging voltage and amperage. Additionally, the system includes AC power-on diagnostics with pass/fail status indicators and discreet fault indicators for issues such as mis-wiring or adverse battery bank conditions.

Advanced Cooling and Safety Features

Automatic Fan Speed Control

Ensures quiet operation with innovative front exhaust design that prevents airflow restriction and maintains effective cooling.

Temperature Compensation & Safety

The ProNauticP includes a remote temperature probe for automatic temperature compensation, ignition protection, and current limiting. It is built to comply with Marine ULc 1236, CE, CTick, and FCC Class B standards, ensuring reliable and safe operation in marine environments.
