BMV-712 Smart Retail Victron Energy battery monitoring module

The BMV-712 Smart is a high precision battery monitor. The essential function of a battery monitor is to calculate ampere hours consumed and the state of charge of a battery. Ampere hours consumed are calculated by integrating the current flowing in or out of the battery.

With Bluetooth built-in, the BMV Smart is ready for the Internet of Things (IoT) era. With Bluetooth being implemented in most other Victron Energy products, wireless communication between products will simplify system installation and enhance performance.

Use a smartphone or other Bluetooth enabled device to:

Customize settings

Monitor all important data on single screen

View historical data

Update the software when new features become available

Easy to install

All electrical connections are to the quick connect PCB on the current shunt. The shunt connects to the monitor with a standard RJ12 telephone cable. Included: RJ 12 cable (10 m) and battery cable with fuse (2 m); no other components needed.

Also included are a separate front bezel for a square or round display appearance, a securing ring for rear mounting and screws for front mounting.

Midpoint voltage monitoring

One bad cell or one bad battery can destroy a large, expensive battery bank. When batteries are connected in series, a timely warning can be generated by measuring the midpoint voltage. Please see the BMV manual, section 5.2, for more information.

Very low current draw from the battery

Current consumption: 0,7Ah per month (1mA) @12V and 0,6Ah per month (0,8mA) @ 24V

Especially Li-ion batteries have virtually no capacity left when discharged until low voltage shutdown. After shutdown due to low cell voltage, the capacity reserve of a Li-ion battery is approximately 1Ah per 100Ah battery capacity. The battery will be damaged if the remaining capacity reserve is drawn from the battery. A residual current of 10mA for example may damage a 200Ah battery if the system is left in discharged state during more than 8 days.

Bi-stable alarm relay

Prevents increased current draw in case of an alarm.

Standard features:

Battery voltage, current, power, ampere-hours consumed and state of charge

Remaining time at the current rate of discharge

Programmable visual and audible alarm

Programmable relay, to turn off non critical loads or to run a generator when needed

500 Amp quick connect shunt and connection kit

Shunt selection capability up to 10.000 Amps

VE.Direct communication port

Stores a wide range of historical events, which can be used to evaluate usage patterns and battery health

Wide input voltage range: 6,5 – 70V

High current measurement resolution: 10 mA (0,01A)

Low current consumption: 2,9Ah per month (4mA) @12V and 2,2Ah per month (3mA) @ 24V

In the Support tab there is an instructional video on the installation of the BMV-712 Smart monitor and on the synchronization of lithium-ion batteries and optimization of the synchronization parameters.
