ProMariner - ProIso Charge 150 0 Voltage Loss Isolator - 24V, 1 Alternator, 3 Batteries

Intelligent Zero Voltage Loss Battery Isolation and Charging

The ProMariner ProIsoCharge 150 is a cutting-edge battery isolator designed to optimize charging efficiency for marine applications. Engineered with advanced digital performance technology, this isolator ensures zero voltage loss, providing full alternator output distribution while prioritizing engine battery health. By intelligently managing charging between multiple battery banks, it enhances battery longevity and maximizes onboard power availability. Ideal for single alternator systems supporting up to three independent battery banks, it offers a seamless and efficient charging solution for boats requiring reliable power distribution.

Advanced Digital Charging Technology

Equipped with ProMar Digital Performance Zero Volt Loss Isolation, this system actively monitors battery status and dynamically allocates power where it's needed most. The intelligent software prioritizes charging for discharged battery banks while maintaining the health of engine start batteries. This ensures that essential onboard power systems receive energy without overburdening the alternator.

Real-Time LED Status Indicators

The ProIsoCharge 150 includes highly visible LED indicators to provide instant feedback on alternator power and battery charging status. Fault LEDs alert users to high or low alternator output, over-voltage conditions, and any irregularities in the battery banks, ensuring optimal system monitoring and maintenance.

Ignition-Controlled Smart Charging

Designed for efficiency and safety, this unit features Distributed On Demand™ battery bank management, which activates only when the ignition is powered on. This prevents unnecessary drain on batteries when the system is not in use, further enhancing reliability.

Precision Alternator Control Compatibility

For advanced marine charging setups, the ProIsoCharge 150 supports advanced regulator remote sensing, enabling precise alternator algorithm control. This compatibility ensures optimized charging performance when used with alternators featuring external regulators.

Built for Marine Durability

Constructed with a waterproof IP66-rated housing, this isolator is built to withstand harsh marine environments. Its modular design allows for easy installation, complete with terminal stud insulator boots and a protective snap-on safety cover for added security.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
