ProIsoCharge delivers digitally controlled alternator output distribution while protecting the health of engine start batteries. An industry changing design that provides intelligent and zero voltage loss isolation, charging of up to 3 other battery banks off a single alternator (model specific). For dual engine applications, ProIsoCharge offers an exclusive 2 alternator input model with up to 4 battery banks. Smart enough to provide priority charging to a battery bank that's under load by taking fully charged batteries off line. The all-in-one design eliminates the need for multiple voltage sensitive relays to charge multiple battery banks simultaneously, saving space, installation time and cost. Ensuring fully charged batteries and faster charge times, ProIsocharge eliminates the typical alternator voltage loss of 0.6VDC that's commonly associated with traditional diode based isolators. Installed with the ProNauticP Series, a boat owner can enjoy the full benefit of shore power and on the water charging. Designed to provide more time on the water enjoying what you like most... boating.

Intelligent Alternator Power Distribution System

ProMar Digital Performance Zero Volt Loss Isolation and Charging
All digital design delivers active battery status and automatic engine battery healthpriority while digitally distributing the full output of your engine's alternators.

Intelligent Isolation and Charging Software Control
ProIsoCharge's intelligent software control provides priority charging to a battery bank thatis under load (i.e house bank or power inverter bank) by taking fully charged batteries off lineand priority charging discharged battery banks, while insuring the health of the engine batteries.

The ProMariner ProIsoCharge120 is a sophisticated digital battery isolator designed for marine and vehicle applications requiring efficient alternator power distribution. This unit features a 12V system voltage and can deliver up to 120 amps of alternator output, making it suitable for high-demand setups. Its compact size and lightweight build facilitate straightforward installation in tight spaces, and its robust construction ensures durability in harsh environments. The ProIsoCharge120 is engineered to optimize engine starting battery health while simultaneously charging multiple auxiliary batteries, supporting up to three battery banks for single or dual engine configurations, with an optional model capable of handling four banks with dual alternator inputs. This flexibility makes it an ideal choice for complex power systems on boats, RVs, and other vehicles requiring reliable power management.

This advanced isolator employs digital technology to actively monitor and control battery charging, eliminating the voltage drops associated with traditional diode-based isolators. It provides zero voltage loss, ensuring maximum power transfer from the alternator to all connected batteries. The intelligent software automatically prioritizes charging to batteries under load, such as house banks or inverter banks, while safeguarding engine start batteries through active health monitoring. The system’s real-time LED indicators give clear visibility into power status, including alternator activity, charging states, and fault conditions like over-voltage or low voltage, enabling quick diagnostics and maintenance.

Designed with user convenience in mind, the ProIsoCharge120 features ignition-controlled operation, activating only when the vehicle or vessel is powered on. It includes an advanced regulator remote sense connection for precise alternator control when paired with compatible regulators. The modular design simplifies installation, complete with terminal insulator boots and a protective safety cover. Built-in safety features such as ignition protection and waterproof IP66 rating ensure reliable performance in marine environments. For comprehensive installation and operational guidance, refer to the included owner’s manual available online. The ProMariner ProIsoCharge120 offers a smart, efficient solution for maintaining battery health, reducing charge times, and maximizing power availability for demanding applications, allowing users to enjoy more time on the water or on the road.
