Victron BMV-712 Black Smart Battery MonitorBluetooth insideWith 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.Download the Victron Bluetooth appUse a smartphone or other Bluetooth enabled device tocustomize settingsmonitor all important data on single screenview historical data, and toupdate the software when new features become available.Easy to installAll 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 monitoringOne 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 batteryCurrent 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 relayPrevents increased current draw in case of an alarm.Other featuresBattery voltage, current, power, ampere-hours consumed and state of chargeRemaining time at the current rate of dischargeProgrammable visual and audible alarmProgrammable relay, to turn off non critical loads or to run a generator when needed500 Amp quick connect shunt and connection kitShunt selection capability up to 10.000 AmpsVE.Direct communication portStores a wide range of historical events, which can be used to evaluate usage patterns and battery healthWide input voltage range: 6,5 – 70VHigh current measurement resolution: 10 mA (0,01A)Additional input to measure voltage (of a second battery), temperature or midpoint voltage, and corresponding alarm and relay settings
