The Balmar SmartShunt N2K 350AMP 12-48VDC for SG200 Display is a multi-bank battery monitoring and DC system integration module designed for marine electrical installations. This device expands monitoring capabilities beyond the primary battery bank while simultaneously integrating NMEA 2000 (N2K) network connectivity, enabling seamless communication with compatible marine displays and gateway systems. The 350-amp shunt rating accommodates high-current marine applications including large engine start batteries, auxiliary power systems, and integrated solar or wind charging arrays.
Operating across 12V to 48V DC configurations, the SmartShunt delivers real-time current, voltage, and state-of-charge data with precision essential for systems where battery management directly impacts vessel safety and operational capability. The N2K adapter enables direct integration into modern marine networks, allowing operators to consolidate battery telemetry on the SG200 display or compatible chartplotters without requiring separate analog gauges. Installation requires either the SG200 display unit or a Bluetooth Gateway (both sold separately) for initial programming and ongoing data access—a standard configuration across professional marine electrical systems.
This module addresses the complexity of multi-battery vessel systems where auxiliary banks, house loads, and engine starts must be monitored independently. Operators managing trawlers, offshore support vessels, expedition yachts, and hybrid power systems rely on accurate shunt-based monitoring to prevent deep discharge, optimize charging, and diagnose electrical faults before they cascade into critical failures. The SmartShunt's 350-amp capacity and multi-voltage compatibility make it suitable for vessels ranging from mid-size cruising sailboats to commercial fishing platforms and offshore workboats. Note: this product is not returnable to the original point of purchase; manufacturer support should be contacted directly for technical issues or warranty concerns.
