Victron Black Smart BMV-712 Battery Monitor: Advanced Battery Management
for Your RV or Off-Grid Setup
Highly Accurate Battery ‘Fuel Gauge’, Time-to-Go Indicator, and More
With the BMV-712, you can rely on precise tracking of your battery's remaining
capacity. This advanced battery monitor considers variables like ampere-hours
consumed, discharge current, temperature, and battery age. Its software
algorithms work out these complexities to provide detailed information not
just on voltage, current, and ampere-hours consumed, but also on state of
charge, time-to-go, and power consumption in Watts. Moreover, the BMV-712 adds
an extra input to measure a second battery's voltage, temperature, or midpoint
voltage.
Simple Installation Process
Installing the BMV-712 is as simple as it gets. All electrical connections
link to the quick connect PCB on the current shunt, which connects to the
monitor with a standard RJ12 telephone cable. The package includes a 10m RJ 12
cable and a 2m battery cable with fuse. No additional components needed! The
package also comes with a separate front bezel for a square or round display,
a rear mounting securing ring, and screws for front mounting.
Effortless Programming with Your Smartphone
Setting up the BMV-712 is a breeze, thanks to its quick install menu and
detailed setup menu with scrolling texts. For an even simpler solution, you
can download our smartphone app and manage settings from there.
Midpoint Voltage Monitoring – Exclusive to BMV-702 and BMV-712
Previously a feature of large, industrial battery banks, midpoint voltage
monitoring is now accessible and affordable with the BMV-712. This feature is
essential for monitoring any battery bank as it alerts you to any deviations
that can point to a problem with your battery. Following an alarm for midpoint
voltage deviation can save your expensive battery from severe damage. Consult
the BMV manual for more detailed information.

- 500 Amp quick connect shunt and connection kit with shunt selection up to 10,000 Amps
- VE.Direct communication port
- Records a wide range of historical events to assess usage patterns and battery health
- Wide input voltage range: 6.5 – 95V
- High current measurement resolution: 10 mA (0.01A)
- Low current consumption: 2.9Ah per month (4mA) at 12V and 2.2Ah per month (3mA) at 24V
Additional Features Exclusive to BMV-712
The BMV-712 offers extra input to measure voltage (of a second battery),
temperature, or midpoint voltage, and corresponding alarm and relay settings.
About Midpoint Voltage
When batteries are connected in series, one bad cell or battery can wreak
havoc on your large, expensive battery bank. Timely warnings can be generated
by measuring the midpoint voltage. For more information, consult section 5.2
of the BMV manual. To maximize the service life of series-connected batteries,
we recommend our Battery Balancer (BMS012201000).
Bluetooth Connectivity Inside (Exclusive to BMV-712)
With built-in Bluetooth, the BMV-712 is ready for the Internet of Things (IoT)
era. As Bluetooth is implemented in most other Victron Energy products,
wireless communication between products will simplify your system installation
and enhance performance. Plus, the bi-stable alarm relay prevents increased
current draw in case of an alarm.

Product Uses
The BMV-712 is designed to offer comprehensive monitoring of your battery bank
in various scenarios, such as:
-
RVs: Track your battery usage and avoid unexpected power shortages during your road trips. The Bluetooth connectivity enables you to monitor your battery status without needing to leave the driver's seat.
-
Off-Grid Solar Systems: The BMV-712 helps you monitor and manage your power consumption effectively, making your off-grid living more reliable and sustainable.
-
Marine Applications: Use it in your yacht or boat to keep track of your marine battery bank, ensuring a smooth and worry-free sea journey.
Frequently Asked Questions (FAQs)
- What are the main differences between the BMV-712 and the BMV-700?
The BMV-712 has all the features of the BMV-700, but it also includes an extra
input to measure a second battery's voltage, temperature, or midpoint voltage.
Additionally, the BMV-712 has built-in Bluetooth for easy wireless setup and
monitoring.
- How does the BMV-712 compare to the SmartShunt?
The SmartShunt is essentially a BMV with Bluetooth and without a display. The
BMV-712, on the other hand, has a physical display and also includes
Bluetooth. The decision between the two depends on your preference for a
physical display and the specific monitoring needs of your system.
- What is midpoint voltage monitoring?
Midpoint voltage monitoring is a feature that monitors the voltage halfway
along a string of batteries. If there's a significant or increasing deviation
from the expected midpoint voltage, it indicates a potential problem with one
of the batteries in the string. This feature can help prevent severe damage to
an expensive battery bank.
