Meet the ProMariner ProIsoCharge150 Zero Volt Loss Isolator for 24V systems — a digital, intelligent charging solution that maximizes alternator output while protecting engine start batteries. Designed to isolate and charge up to 3 additional battery banks from a single alternator, this model delivers more time on the water with faster, more reliable charging.

Key features and benefits

• Zero volt loss isolation eliminates the traditional 0.6 VDC drop found in diode-based isolators, ensuring fully charged batteries and quicker recharge times.
• Intelligent charging with priority uses smart software to protect engine batteries while prioritizing discharged banks under load, temporarily taking fully charged batteries offline to speed up charging where it’s needed most.
• Ignition Controlled Distributed On Demand activates battery management only when ignition power is on, preserving energy when the boat isn’t running.
• Real-time status LEDs provide at-a-glance indication of alternator power, charging status, and fault conditions (over/under voltage, high voltage, etc.).
• Advanced regulator compatibility with remote sense support for precise control on alternators with advanced regulators.
• Easy installation with a modular design, including terminal stud insulator boots and a protective snap-on safety cover.
• Rugged and safe for marine use, ignition-protected and IP66 waterproof rating.
• Versatile power management isolates and charges up to 3 independent battery banks from a single alternator; optional 2 alternator input model supports dual-engine boats with up to 4 banks.
• Space-saving, maintenance-friendly replaces bulky diode isolators and relays, reducing wiring complexity and improving reliability.
• Shore power synergy designed to pair with ProNauticPSeries for shore power and on-water charging, so you’re ready for more time on the water.
