Victron BMV-712 Smart: The Ultimate Precision Fuel Gauge for Your Batteries

The Victron Energy BMV-712 Smart is the industry-standard battery monitor for users who refuse to guess their power levels. Unlike basic voltmeters, the BMV-712 acts as a high-precision fuel gauge, calculating Amp-hours consumed and State of Charge (SOC) by integrating the actual current flowing in and out of your battery bank. With Bluetooth built-in, you can monitor your entire system wirelessly via the VictronConnect app or directly on the high-contrast backlit display.

The "Smart" advantage extends beyond just convenience. The BMV-712 features a programmable relay that can automatically trigger a generator or signal an alarm based on SOC or voltage levels. It also includes an auxiliary input that can be configured to monitor the voltage of a second battery (like a starter battery), track battery temperature, or monitor midpoint voltage in series-connected banks to detect failing cells before they destroy your system.

Key Performance Features:

• Comprehensive Data Tracking: View battery voltage, current, power, Amp-hours consumed, and estimated "time-to-go" at your current rate of discharge.
• Dual-Battery Monitoring: Use the secondary input to keep an eye on your engine's starter battery while simultaneously monitoring your primary deep-cycle house bank.
• Extreme Efficiency: Advanced engineering results in a very low current draw (<1mA with backlight off), ensuring the monitor itself doesn't drain your batteries during storage.
• Simplified Installation: All electrical connections are made to the quick-connect PCB on the included 500A shunt. A single RJ12 cable connects the shunt to the head unit.
• Bistable Relay: A programmable internal relay allows you to control external equipment, such as turning off non-critical loads or starting a generator when capacity is low.

Technical Tip: For the most accurate "State of Charge" readings, ensure the BMV-712 is the only connection to your battery's negative terminal. All other negative leads (loads and chargers) must connect to the "Load" side of the shunt.
