Detailed description

Designed for precise energy management, the M2 DC Multimeter with SoC 1830 from BLUE SEA SYSTEMS is an OLED digital monitor that measures current, voltage, and state of charge (SoC) of batteries. It differs from the 1832 (ammeter) and 1833 (voltmeter) models in the same M2 OLED range by its ability to provide complete state-of-charge monitoring for a battery, while measuring the voltage of up to three battery banks and the current of one bank.

Measurement and Display Capabilities

This multimeter integrates a self-dimming 55 mm x 28 mm OLED screen, offering a 0.01V DC resolution and ± 1.0% accuracy for voltage. It operates on a 7V to 70V DC power range, compatible with 12V, 24V, 36V, and 48V systems. Current is measured over a range of -500A to 500A with the included 500A shunt, with programmable capacity up to 5000A via external shunts. Power consumption ranges from 0.3W to 1.0W.

Features and System Integration

The M2 DC Multimeter with SoC 1830 is equipped with 80dB (or 92dB depending on source) audible alarms for high current, high/low voltage, and low battery thresholds. An isolated 500mA MOSFET relay is included for activating external circuits. The device is protected against powerful water jets (IP66) on its front face when mounted according to instructions. It enables continuous monitoring of state of charge, recording values every 15 minutes and restoring them after a power outage.

« Expert analysis: M2 DC Multimeter 1830 and energy management »

The BLUE SEA SYSTEMS DC multimeter M2 1830 with SoC is an essential instrument for managing DC systems on board, particularly on cruising sailboats and vessels requiring detailed monitoring of their battery banks. Unlike simple ammeters or voltmeters, the 1830 provides a holistic view of the service bank's health (SoC, remaining Ah, charge cycles) while allowing monitoring of two additional banks (start, thruster, etc.).

Its installation requires precise positioning of the supplied 500A shunt on the negative side of the service bank to ensure reliable current measurement and SoC calculation. It is crucial to connect it to a 24/7 non-switched circuit for continuous and accurate SoC monitoring. The built-in MOSFET relay output is an asset for triggering external alarms or automations based on configurable voltage or current thresholds, offering flexibility for integration into more complex systems. Its compatibility with shunts up to 5000A makes it adaptable to high-power installations, although the 500A shunt is sufficient for most classic marine applications.

Frequently Asked Questions

Need help? Contact us

What is the M2 DC multimeter with SoC, and what is it used for?

The BLUE SEA SYSTEMS M2 DC multimeter with SoC (State of Charge) is a digital OLED monitor designed for precise energy management. It measures current, voltage, and battery state of charge. It is particularly useful for monitoring the full state of charge of a battery, the voltage of up to three battery banks, and the current of one bank.

What are the main measurements performed by the M2 DC multimeter with SoC?

The M2 DC multimeter with SoC precisely measures:

Voltage for up to three battery banks (with 0.01V DC resolution and ±1.0% accuracy).Current for one battery bank (with a range of -500A to 500A with the included shunt, and up to 5000A with external shunts).State of charge (SoC), capacity, remaining amp-hours (Ah), and charge cycles for the main battery (Battery 1).

What are the dimensions of the OLED screen on the M2 multimeter?

The M2 DC multimeter with SoC features a self-dimming OLED screen measuring 55 mm x 28 mm.

Is the M2 multimeter water-resistant?

Yes, the front face of the M2 monitor is rated IP66, meaning it is protected against powerful water jets when installed according to the instructions. However, the rear of the unit is not waterproof and must not be exposed to water.

What is the required input voltage range for the M2 multimeter?

The M2 DC multimeter with SoC operates on an input voltage range of 7V to 70V DC.

Which battery system types are compatible with the M2 multimeter?

The M2 multimeter is compatible with 12V, 24V, 36V, and 48V battery systems.

Can the M2 multimeter monitor multiple battery banks?

Yes, the M2 DC multimeter with SoC (model 1830) can measure the voltage of up to three battery banks and the current of one battery bank.

What are the alarm features of the M2 multimeter?

The M2 multimeter is equipped with 80 dB (or 92 dB depending on the source) audible alarms for the following thresholds:

High currentHigh/low voltageLow battery

Does the M2 multimeter have an output relay?

Yes, the M2 multimeter includes an isolated 500 mA MOSFET relay. This relay can be used to activate external circuits based on configured alarm thresholds.

Does the M2 multimeter retain data in the event of a power outage?

Yes, all M2 multimeter settings are stored in flash memory and retained even when the unit is powered off. Additionally, the SoC 1830 monitor logs the current charge state and charge cycle values every 15 minutes. Upon restart or power loss, it restores these values to their last saved state.

What is the required mounting hole size to install the M2 multifunction display?

For standard installation, the M2 multifunction display requires a mounting hole with a diameter of 2-1/8 inches (54 mm).

What is the maximum panel thickness for installing the M2 multimeter?

The M2 multimeter can be mounted on a panel with a maximum thickness of 1 inch (25 mm).

Where should the shunt be connected for accurate state-of-charge monitoring?

For accurate state-of-charge (SoC) monitoring with model 1830, the shunt must be connected between the negative terminal of battery 1 (house battery) and the main negative bus. All loads and charging sources must have their negative terminals connected to the main negative bus, except the negative source of the M2, which must be directly connected on the battery side of the shunt. The shunt’s sensing wires must be a twisted pair.

What are the prerequisites before starting installation of the M2 multimeter?

Before starting installation, it is imperative to:

Disconnect the inverter power cables from the battery if an inverter is installed.Stop and render any AC generator inoperative if a generator is installed.Verify that no other DC or AC source is connected to the boat's wiring.Ensure that battery 1 (house battery) is fully charged for the initial setup.

What wire gauges are recommended for M2 multimeter connections?

The M2 multimeter's 8-pin connector supports wire sizes from 16 to 26 AWG. For shunt sensing wires, a twisted pair is recommended for accurate state-of-charge (SoC) calculation.

Which battery types can the M2 multimeter monitor?

The M2 multimeter can be configured to monitor various battery types, including:

FLStd (Standard flooded lead-acid batteries)AGM (Standard AGM batteries)TPPL (Thin-plate pure lead AGM batteries)Gel (Gel batteries)FLRsv (Flooded lead-acid standby batteries)FLLoM (Sealed low-maintenance lead-acid batteries)CFoam (Carbon foam AGM batteries)Lilon (Lithium-Ion batteries)

Can the M2 multimeter be used with current shunts larger than the one included?

Yes, although the M2 multimeter is supplied with a 500A/50mV shunt, it can display up to +/- 5000A. This requires the use of a 5000A/50mV shunt, which is not included and must be purchased separately.

What is the power consumption of the M2 multimeter?

The M2 multimeter's power consumption ranges from 0.3W to 1.0W. This consumption varies depending on the supply voltage, display intensity, and standby mode.
