Blue Sea Systems 1830 M2 DC State of Charge (SoC) Digital Monitor | MPN: 1830
Take total control of your vessel or rig’s electrical system with the Blue Sea Systems 1830 M2 DC State of Charge (SoC) Digital Monitor (Part Number: 1830). Engineered for high-precision battery monitoring in marine, RV, and off-grid power systems, the M2 1830 tracks battery capacity, net current flow, and voltage levels to ensure you never run out of power unexpectedly.
Featuring a high-contrast, self-dimming OLED display, the M2 1830 monitors the State of Charge (SoC) and current on one primary battery bank while simultaneously monitoring voltage across up to 3 independent battery banks. Compatible with 12V, 24V, 36V, and 48V DC systems (7V to 70V DC operating range), this monitor includes a 500A/50mV shunt and features customizable audible alarms and an integrated MOSFET relay for external automated control.
Key Features & Performance Advantages
-
Comprehensive Battery Health Tracking: Real-time percentage display of State of Charge (SoC), remaining capacity, and net ammeter current draw/charge.
-
Multi-Bank Voltage Monitoring: Measures voltage for up to 3 separate DC battery banks (7–70 VDC range).
-
High-Contrast OLED Display: Bright, ultra-clear screen with customizable text/graphic modes and automated self-dimming for low-light or nighttime navigation.
-
Included 500A Shunt: Comes complete with a 500A / 50mV precision brass shunt for accurate current measurement from -500A to +500A.
-
Customizable Alarms & MOSFET Relay: Features an 80dB internal audible alarm for low/high voltage, high current, and low battery capacity, plus an isolated 500mA MOSFET relay to trigger external relays or warning lights.
-
IP66 Waterproof Front Face: Waterproof seal withstands high-pressure water washdowns and harsh saltwater environments.
-
Non-Volatile Memory: Retains historical state-of-charge data and system configuration settings even during complete power loss.
