Pro Mariner Battery Isolators & Voltage Sensitive Relays
Pro Mariner's ProIsoCharge Technology
When it comes to battery isolators and voltage sensitive relays, Pro Mariner has revolutionized marine power management with their flagship ProIsoCharge series. These systems provide intelligent and zero voltage loss isolation, charging of up to 3 other battery banks off a single alternator, representing a significant departure from traditional diode-based designs that typically rob systems of valuable charging efficiency.
ProIsoCharge eliminates the typical alternator voltage loss of 0.6VDC that's commonly associated with traditional diode based isolators, ensuring faster charge times and fully charged batteries when you need them most. This zero-loss architecture is crucial for vessels with complex electrical systems, where every tenth of a volt matters for battery health and longevity.
Intelligent Software-Controlled Charging
What truly sets Pro Mariner's battery isolators apart is their intelligent software control system. The technology is smart enough to provide priority charging to a battery bank that's under load by taking fully charged batteries off line, ensuring that your house bank or inverter loads receive the charging current they need while protecting the health of your engine start batteries. This dynamic power distribution eliminates the manual intervention required with older relay systems.
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. For boat owners upgrading from conventional ACR setups or multiple relay configurations, the ProIsoCharge series simplifies installation while delivering superior performance through its modular, waterproof design.
ProIsoCharge Product Range
Pro Mariner offers ProIsoCharge models tailored to different marine electrical architectures. The ProIso Charge series allows you to save space and time by eliminating traditional diode-based isolators, with configurations ranging from single-alternator units supporting 2-3 battery banks up to an exclusive 2 alternator input model with up to 4 battery banks for dual-engine applications. Available in 12V and 24V systems with amperage ratings from 120 to 250 amps, these isolators handle everything from compact cruisers to larger vessels with substantial house loads.
Each unit features real-time LED status indicators that display alternator output and battery bank charging status, along with fault detection for high/low alternator conditions and over-voltage protection. ProIsoCharge is ignition controlled and will only activate with ignition power on, and is Advance Regulator Ready with remote sense connection provided for precision alternator algorithm control, making these isolators compatible with modern high-output alternators and multi-stage charging systems.
Marine-Grade Reliability
Fitted with gold-plated terminals for improved efficiency, Pro Mariner isolators are built for challenging conditions and benefit from an IP68 rating in their traditional multi-battery isolator line. The ProIsoCharge series carries IP66 waterproof protection and includes all terminal stud insulator boots with protective snap-on safety covers, ensuring long-term reliability in harsh marine environments. For boat owners seeking to optimize their charging systems while reducing complexity, Pro Mariner's battery isolators represent a proven solution backed by decades of marine power experience.
