VictronVictron BMV 712 battery monitor for two batteries with Bluetooth including shunt. Battery 1 volts, amps, amp-hours and Battery 2 volts.
The BMV-712 is the latest high precision battery monitor from Victron. The BMV-712 monitors voltage and current of a single battery bank and calculates power, state-of-charge and time-to-go. It also features an additional voltage input that can be used to measure an auxiliary or starter battery voltage, midpoint voltage or temperature with the optional temperature sensor. Data can be transferred to smartphones or computers with the inbuilt bluetooth module and external alarms can be triggered with the relay contact.
Installation is simply a case of connecting the supplied shunt in the negative battery cable, mounting the monitor in a 52mm diameter hole and connecting the wires. An optional wall enclosure is available if surface mounting is preferred.
Bluetooth Inside: 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.
Download the Victron Bluetooth App: Use a smartphone or other Bluetooth enabled device to - customize settings, - monitor all important data on single screen, - view historical data, and to - 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. We recommend our Battery Balancer (BMS012201000) to maximize service life of series-connected lead-acid batteries
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.
