Meet the ProMariner ProIsoCharge120 Zero Volt Loss Isolator, the digital backbone for intelligent power management on the water. This 12V system uses advanced software to actively monitor battery status, prioritize engine battery health, and distribute the full output of your alternator to up to three independent battery banks with zero volt loss. More charge, less downtime, and bigger smiles on every voyage.
Key advantages
-
Zero volt loss isolation eliminates the typical 0.6 VDC drop of traditional diode-based isolators, delivering faster, more efficient charging to all connected battery banks.
-
Intelligent digital performance continuously monitors battery health and dynamically allocates charging where it’s needed most, prioritizing the bank under load (house bank or inverter) while protecting engine start batteries.
-
Ignition-controlled, on-demand power management activates only with ignition power, ensuring safe operation and energy efficiency.
-
Advanced regulator compatibility with a remote sense connection provides precision control for alternators equipped with an advanced regulator.
-
Real-time status at a glance highly visible LEDs indicate alternator power, charging status, and fault conditions, including high/low output and over-voltage warnings.
-
Easy installation with a modular design, includes all terminal boots and a protective snap-on safety cover for quick setup.
-
Rugged protection ignition-protected and IP66 waterproof rated for harsh marine environments.
-
Versatile, multi-bank charging isolates and charges up to 3 independent battery banks from a single alternator (model-specific). For dual engine systems, an exclusive 2 alternator input model supports up to 4 banks.
-
Space-saving, maintenance-free replaces bulky diode isolators and voltage-sensitive relays, simplifying wiring and reducing clutter.
-
Shore power ready pairs with ProNauticPSeries to maximize on-the-water charging and shore power capabilities, giving you more time doing what you love—boating.
