Victron Battery Monitor BMV-712 Smart

The BMV-712 battery monitor measures with very high precision within a supply voltage range of 6.5–70 VDC. The essential function of a battery monitor is to calculate battery status and ampere-hours consumed. The BMV-712 battery monitor displays the battery voltage, current, ampere-hours consumed, remaining battery capacity, and time remaining. These last two parameters ensure that you can read the remaining battery capacity as accurately as at a gas pump. An advanced backlit LCD display clearly shows all values. Built-in Bluetooth. With built-in Bluetooth, the BMV Smart is ready for the era of the Internet of Things (IoT). Because Bluetooth is implemented in most other Victron Energy products, wireless communication between products will simplify system installation and improve performance.

The shunt connects to the display using a standard RJ12 telephone cable. Included: RJ 12 cable (10 m) and battery cable with fuse (2 m); no other components are required. Also included is a separate bezel for a square or round display front appearance, a retaining ring for rear mounting, and screws for front mounting. Midpoint Voltage Monitoring A single bad cell or battery can destroy a large, expensive battery bank. If batteries are connected in series, an early warning can be generated by measuring the midpoint voltage. See the BMV manual, section 5.2, for more information. We recommend a Battery Balancer to maximize the lifespan of series-connected lead-acid batteries. Very low battery current consumption. Current consumption: 0.7 Ah per month (1 mA) at 12 V and 0.6 Ah per month (0.8 mA) at 24 V. Lithium-ion batteries, in particular, have virtually no remaining reserve capacity when discharged until low-voltage shutdown. After shutdown due to low cell voltage, the remaining capacity of a lithium-ion battery is approximately 1 Ah per 100 Ah of battery capacity. The battery will be damaged if the remaining reserve capacity is drained. For example, a residual current of 10 mA can damage a 200 Ah battery if the system remains in a discharged state for more than 8 days. Bistable alarm relay. Prevents increased current consumption in the event of an alarm.
