Victron BMV-712 Smart battery health monitor

Victron BMV-712 Smart External module/display BMV-712 Smart (Battery Monitor Voltage) is a new highly accurate system for monitoring two independent batteries. Why monitor the operating status of the battery? For its longer life! Detailed battery monitoring allows us to detect any operational deficiencies with quick correction to support long battery life. Suitable for all types of lead batteries including fleece (AGM) and gel. Simple battery capacity adjustment (factory setting at 200 Ah). Auto-detection of voltage 12, 24, 36, 48, 60, 120, 144 and 288 V (note that it varies by model). Regular automatic calibration of the device for reliable display of measured data (can also be performed manually). The BMV-700H version is designed for systems with high operating voltage (DC 70 to 350 V), the BMV-702 version is designed for monitoring two batteries, monitoring battery temperature or average value. The monitor is also suitable for Li-on batteries. The Battery monitor BMV-712 Smart is also equipped with integrated Bluetooth technology compared to the BMV-702 model. The BMV-712 Smart, thanks to the Bluetooth wireless communication technology, which is implemented in most other Victron Energy products, will simplify the installation of the system and increase its performance. Basic displayed values: current battery voltage (V) current current (A) that goes into (positive values - charging) or out (negative values - discharging) of the battery current power (W) that goes into (positive values - charging) or out (negative values - discharging) of the battery (multiple of voltage and current) total sum of energy taken from the battery to power appliances in ampere-hours (Ah) current battery charge level in percent expected (sophisticatedly calculated) length of time in hours to 50% battery discharge at a given energy consumption The tracker stores selected historical data and achieved limit values: deepest achieved battery discharge level last battery discharge level number of completed battery discharge/charge cycles average battery discharge value number of full battery discharges maximum achieved battery voltage minimum achieved battery voltage number of days since the last full battery charge Technical parameters: energy consumption with unlit display and relay off: 1 mA (12 V) and 0.8 mA (24 V) power consumption with unlit display and relay closed: 1 mA (12 V) and 0.8 mA (24 V) operating voltage: 12, 24 and 48 V (autodetection) maximum current through the shunt: -500 to +500 A (discharging and charging the battery) maximum deviation when reading voltage: ±0.01 A at voltage 0 – 100 V maximum deviation when reading current: ±0.01 A with 500 A shunt maximum deviation when reading capacity: ±0.1 Ah at battery capacities 0 – 100 Ah maximum deviation when reading capacity: ±1 Ah at battery capacities 100 – 9999 Ah maximum deviation when reading state of charge: ±0.1% maximum deviation when estimating remaining time: ±1 hour (in the range 1 - 240 hours) maximum deviation when reading power: ±1 W in the range from -100 W to 1 kW total battery capacity: 20 - 9999 Ah operating temperature range: -20 to +50 °C circular diameter of the tracker itself: 63 mm square size of the tracker cover: 69 x 69 mm depth of the tracker itself: 31 mm switched relay: 60 V (1 A) maximum weight of the tracker itself: 70 g weight of the shunt: 315 g connecting screws of the shunt: M10 material: plastic The tracker performs sophisticated monitoring of supplied and consumed energy together with taking into account the adjustable value of the Peukert exponent (the greater the energy consumption, the relatively lower the amount of available energy in the battery and vice versa) and battery efficiencye to estimate the current amount of energy (Ah) and the battery charge level (in percent). To correctly display the amount of available energy in the battery, it is necessary that all energy entering and leaving the battery passes through the shunt. The tracker itself can be integrated into the wall without the need for access from the back (covered screws). For currents greater than 500 A, a replacement shunt designed for currents of 1000 and 2000 A can be supplied. Shunts up to a maximum current of 9999 A with a voltage range of 1 - 100 mV (both adjustable) can be used on the tracker. The tracker has a switching relay. This is activated/deactivated based on the measured battery charge level. The factory setting is to switch on when the battery charge level drops below 50% and switch off when the charge level reaches 90%. These values can be changed in the settings. The switching logic can also be reversed, i.e. the relay is switched on by default, off by default. The relay can be used to switch on/off devices such as an external alarm, generator, etc. The tracker can be connected to other devices. Possibility of connecting the tracker to a large color display Color Control GX with free graphical visualization of measured values on the portal https://vrm.victronenergy.com/user/register (can be tested on functional systems by entering the username: demo@victronenergy.com and password: vrmdemo). To connect the BMV-700 tracker to the Color control GX display, it is necessary to purchase either a VE.Direct cable or a VE.Direct-USB communication interface. The package includes: the tracker itself with a backlit digital display and controls a plastic tracker cover measuring 69 x 69 mm a 500 A (50 mV) shunt designed for a maximum current of 500 A (installed on the negative battery cable) a 10-meter long RJ-12 communication and power UTP cable (connecting the tracker itself to the shunt) a 2-meter long installation cable with a fuse for connection to the positive cable BASIC SPECIFICATIONS Interface: Bluetooth, RJ-12, VE.Direct, terminal block Supported battery types: lead, VRLA (gel and AGM), Li-ion, LiFePO4 Supply voltage range: DC 6.5 - 70 V Battery capacity: 20 - 9999 Ah Measurement of second battery voltage, temperature or average value: yes Dimensions: 69 x 69 x 31 mm VictronConnect application for Android mobile devices VictronConnect application for iOS mobile devices Application VictronConnect for Mac devices The application is also available for download on the Victron Energy manufacturer's website (Mac/Windows/Linux/iOS/Android): https://www.victronenergy.com/support-and-downloads/software#victronconnect-app
