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.

Delivery and tracking
Deliveries are handled by trusted carriers such as USPS, UPS, FedEx, and DHL. Estimated arrival times appear at checkout and depend on your location and the service you choose. These are estimates and can be affected by customs or carrier disruptions. A shipping confirmation with a tracking link is emailed when your order ships, and tracking may take up to 24 hours to update. You can also view tracking in your account.

Duties, taxes, and support
International customers are responsible for any customs duties, taxes, and fees charged by the destination country. If these charges are refused and a shipment returns to us, the carrier’s return cost and any re-entry customs fees will be deducted from the refund. If your order is late or you need help, contact cs@qualityboatparts.com and we will assist you.

Quality Boat Parts is a reseller. Many items include a manufacturer’s warranty, and all warranty service is handled directly by the manufacturer. We do not manage or administer warranty claims on behalf of customers.

Warranty terms, coverage, and duration are set by each manufacturer. Issues involving defects, repairs, or replacements must be addressed with the manufacturer’s support team. When available, the warranty period is listed on the product page. If it is not shown, contact us or the manufacturer for details before purchasing.

To start a claim, the customer must contact the manufacturer and follow their process. Keep your proof of purchase and original packaging, and register the product if the manufacturer requires it, as these are often needed for warranty service.

We are happy to help you find the right contact or documentation, but we cannot decide outcomes or intervene in claim resolutions. For guidance, email cs@qualityboatparts.com.
