BMV-712 Smart

The BMV-712 Smart is a battery monitor designed by Victron Energy for comprehensive monitoring of battery banks. It allows precise tracking of state of charge, voltage, current, power, consumed ampere-hours, and remaining time via its built-in display or the VictronConnect app on smartphone or tablet.

The BMV-712 Smart provides a full range of battery monitoring features:

Voltage, current, power, consumed amp-hours, and state-of-charge display.Estimation of remaining time under current discharge.Audible and visual programmable alarms.A programmable relay to control non-critical loads or start a generator.Midpoint voltage monitoring for series battery banks.Integrated Bluetooth connectivity for management via the VictronConnect app.Recording of a wide range of historical events and trends.

Yes, the BMV-712 Smart includes Bluetooth connectivity. This feature allows it to communicate wirelessly with the VictronConnect app installed on a smartphone or tablet, simplifying device configuration, monitoring, and software updates.

You can view the data from your BMV-712 Smart in two main ways:

On the display unit: The device has a built-in screen that shows all key information.Via the VictronConnect app: By downloading the VictronConnect app on your smartphone or tablet and connecting via Bluetooth, you can customize settings, monitor all data on a single screen, view history, and update the software.

The BMV-712 Smart is designed for very low current consumption to avoid unnecessarily discharging your battery. Its consumption is approximately 0.7 Ah per month (i.e., 1 mA) for a 12 V system, and 0.6 Ah per month (i.e., 0.8 mA) for a 24 V system.

Yes, the BMV-712 Smart can monitor the mid-point voltage of batteries connected in series. This feature is crucial for quickly identifying a faulty cell or battery, which can prevent premature failure of an expensive battery bank and maximize its lifespan.

The BMV-712 Smart stores a wide range of historical data and trends. It records battery voltage, current, state of charge (SoC) in percentage, as well as auxiliary input data (battery temperature, mid-point deviation, or starter battery voltage). These trend data are stored for a 46-day period, which is useful for assessing usage patterns and battery health.

The BMV-712 Smart supports a wide input voltage range, from 6.5 VDC to 70 VDC. This makes it compatible with a variety of battery systems, including 12 V, 24 V, and 48 V systems.

The BMV-712 Smart provides a high-resolution current measurement of 10 mA (0.01 A). This precision enables detailed monitoring of current flows in your battery system, ensuring reliable tracking of charge and discharge.

The BMV-712 Smart is designed to handle a wide range of battery capacities, from 1 Ah to 9999 Ah. This flexibility makes it suitable for many types and sizes of battery banks, from small installations to larger systems.

The BMV-712 Smart kit includes the following items:

The main BMV-712 Smart monitor unit.A separate bezel for square or round screen appearance.Rear mounting bracket and screws for front mounting.A 500 A / 50 mV current shunt with quick-connect PCB.A standard 10 m RJ12 telephone cable to connect the shunt to the monitor.A 2 m battery cable with fuse for positive connection.

The BMV-712 Smart monitor connects to the shunt via a standard RJ12 telephone cable. A 10-meter RJ12 cable is included in the kit, allowing flexible installation between the shunt (which handles all electrical connections) and the display unit.

The BMV-712 Smart display unit offers flexible mounting options:

Flush mounting: The device is designed for flush installation.Screen appearance: The kit includes a separate front bezel allowing a choice between a square screen (69 x 69 mm) or a round screen (63 mm diameter).Mounting: A mounting ring is provided for rear installation, and screws are included for front mounting.

The BMV-712 Smart is rated IP55, meaning it provides protection against dust and water jets. However, it is not specifically designed for direct outdoor use. It should be installed in a protected environment to ensure longevity and proper operation.

For the basic electrical connection of the BMV-712 Smart:

Connect the negative terminal of your battery to the BATTERY ONLY side of the shunt.Connect the negative terminal of your DC electrical system (loads and chargers) to the LOAD AND CHARGER side of the shunt.Connect one of the supplied power cables (with fuse) to the positive terminal of the battery and the other end to the B1 terminal of the shunt.The shunt must be the first and only component connected directly to the negative pole of the battery.

To monitor the voltage of a second battery with the BMV-712 Smart:

Connect the other supplied power cable between the positive terminal of the second battery and the B2 terminal of the shunt. Connect the negative terminal of the second battery to the LOAD AND CHARGER side of the shunt. This setup allows the BMV-712 Smart to measure the voltage of this auxiliary battery in addition to the main battery.

Yes, for safety reasons, it is imperative to disconnect the negative terminal of the battery before installing the BMV-712 Smart. This prevents accidental short circuits and protects both the installer and the equipment.

Yes, the BMV-712 Smart is compatible with Victron Energy battery balancers. To maximize the lifespan of lead-acid batteries connected in series, using a battery balancer, such as the BMS012201000 model from Victron Energy, is highly recommended. This helps maintain charge balance between batteries and prevents premature failures.

Yes, the BMV-712 Smart can be connected to Victron Energy GX monitoring devices, such as the Color Control GX or the Venus GX. You can connect up to four BMV units directly to a Color Control GX using VE.Direct cables (not included). For connecting an even larger number of BMV units, a USB hub can be used for centralized monitoring. This integration allows complete management and monitoring of your energy system.

Yes, although the BMV-712 Smart comes with a 500 A / 50 mV shunt, the quick-connect PCB of this standard shunt can also be mounted on higher-capacity shunts such as the 1000 A/50 mV, 2000 A/50 mV, and 6000 A/50 mV models. The monitor supports shunt selection up to 10,000 Amperes, offering high flexibility to adapt to various systems.
