Victron BMV-712 Smart Battery Monitor (9-90V)

The Victron BMV-712 Smart is a premium battery monitoring system designed to provide precise, real-time information about your battery bank's condition and performance. Suitable for motorhomes, campervans, caravans, boats, off-grid solar systems, backup power systems, and lithium battery installations, it functions as a highly accurate battery "fuel gauge", displaying state of charge, voltage, current, power consumption, amp-hours consumed, and remaining runtime.

Unlike basic voltmeters, the BMV-712 uses sophisticated battery monitoring algorithms and a precision 500A/50mV shunt to calculate true battery state of charge. Built-in Bluetooth connectivity allows wireless monitoring and configuration through the VictronConnect app without requiring any additional accessories.

The BMV-712 also includes an auxiliary input capable of monitoring a second battery voltage, battery temperature (with optional sensor), or midpoint voltage in larger battery banks, making it ideal for advanced leisure, marine, and renewable energy systems.

Technical Specifications

Monitoring Functions

State of Charge (SOC)

The BMV-712 continuously calculates:

• Battery state of charge (%)
• Voltage
• Current
• Power (Watts)
• Amp-hours consumed
• Remaining battery capacity
• Time remaining until recharge is required

This provides significantly more useful information than battery voltage alone.

Time-To-Go Calculation

The monitor estimates remaining runtime based on current consumption and available battery capacity, helping users manage energy usage more effectively.

Historical Data Logging

The BMV-712 records:

• Deepest discharge
• Average discharge
• Number of cycles
• Total amp-hours consumed
• Voltage events
• Battery performance trends

This information helps assess battery condition and long-term health.

Built-In Bluetooth

The integrated Bluetooth interface allows direct connection to the VictronConnect app.

Using VictronConnect you can:

• Monitor battery status in real time
• Configure monitor settings
• View historical data
• Receive alerts
• Update firmware
• Access advanced battery parameters

No additional Bluetooth dongle is required.

Advanced Monitoring Features

Second Battery Monitoring

The auxiliary input can monitor a separate starter battery or secondary battery bank.

Midpoint Voltage Monitoring

For large series-connected battery banks, midpoint monitoring can identify imbalance issues before they become serious battery faults.

Battery Temperature Monitoring

When connected to the optional temperature sensor, the BMV-712 can measure battery temperature and share that information with compatible Victron devices through VE.Smart Networking.

Victron Ecosystem Integration

The BMV-712 integrates seamlessly with:

• Cerbo GX
• Ekrano GX
• Venus GX
• Colour Control GX
• SmartSolar MPPT Controllers
• MultiPlus Inverter/Chargers
• Quattro Inverter/Chargers
• VRM Remote Monitoring Portal

Battery information can be shared across the entire Victron system using VE.Direct and Bluetooth networking.
