Blue Sea 1830 M2 DC SoC State of Charge Monitor

The Blue Sea Systems 1830 M2 DC State of Charge Monitor delivers precise battery management for DC power systems operating between 8 and 70 volts. This intelligent monitoring device accurately measures state-of-charge across battery banks up to 5,000 amps (500 amps with the included shunt), providing operators with real-time visibility into available power reserves—critical for mission-critical equipment, vessel electrical systems, and off-grid power installations where unexpected power loss creates operational liability.

The monitor features an auto-dimming OLED display engineered for readability across varying light conditions, from bright daylight to low-light tactical environments. Programmable shunt ratios allow customization for different amp-hour capacities and system configurations. A 92-decibel alarm activates on high current draw, high voltage, and low voltage conditions—providing audible alert before system compromise occurs. The isolated MOSFET relay enables load disconnection during critical low-battery conditions, protecting sensitive electronics from voltage sag damage. Current and voltage measurement functions deliver simultaneous data, eliminating the need for separate metering instruments and reducing overall system complexity.

This State of Charge Monitor is engineered for operators managing portable power systems in remote operations, vessel electrical plants, emergency response vehicles, and off-grid installations where battery reserve assessment directly impacts mission success. The combination of voltage monitoring, current measurement, and programmable alarm thresholds addresses the core requirement: knowing precisely when power reserves require replenishment before critical loads fail. Easy adjustment controls and streamlined installation make field deployment straightforward, reducing downtime when power system reconfiguration becomes necessary.

Blue Sea Systems State of Charge Monitors represent the industry standard for DC power system intelligence in marine, tactical, and emergency response applications. The 1830 M2 model integrates proven monitoring technology into a compact form factor suitable for dashboard or panel mounting in confined spaces where equipment real estate is limited.
