Backup Power Systems Ensure readiness and optimal performance of batteries used for emergency power. Industrial & Commercial Use Monitor large battery banks where midpoint voltage detection is critical for maintenance. Built-In Protection Functions The Victron BMV-702 includes robust features to safeguard your battery system. It offers programmable visual and audible alarms for various critical conditions, including low and high battery voltage, low state of charge, high or low temperature (with optional sensor), and significant midpoint voltage deviation. The integrated programmable relay can automatically respond to these alarms, for instance, by disconnecting non-essential loads to prevent deep discharge or by activating a generator when the battery state of charge is low. The unit's IP55 protection category ensures durability in protected indoor environments. Common Questions What is midpoint voltage monitoring? Midpoint voltage monitoring is a feature of the BMV-702 that measures the voltage at the halfway point of a series-connected battery bank. A deviation from the expected half-voltage can indicate an imbalance or a failing cell, allowing for early intervention to prevent damage to the entire bank. Can I connect the BMV-702 to my smartphone? Yes, the BMV-702 features a VE.Direct communication port. To connect to a smartphone or other Bluetooth-enabled device via the VictronConnect app, an optional VE.Direct Bluetooth Smart dongle (not included) is required. Is a shunt included with the BMV-702? Yes, the Victron BMV-702 Black comes complete with a 500 Amp quick-connect shunt and the necessary connection kit, including a 10-meter RJ12 cable and a 2-meter fused battery cable. What is the warranty period for this product? The Victron Battery Monitor BMV-702 Black comes with a 5-year manufacturer's warranty, providing peace of mind regarding its quality and durability. Installation Notes The BMV-702 is designed for flush mounting and includes both square and round bezels for flexible installation. All electrical connections are made to the quick-connect PCB on the current shunt, which then connects to the monitor via a standard RJ12 telephone cable. Ensure proper wiring according to the manufacturer's manual to avoid damage and ensure accurate readings. The unit has an IP55 rating, making it suitable for protected indoor environments; it is not intended for outdoor use. Before You Buy Verify the voltage range (6.5-95 VDC) is compatible with your battery system (12V, 24V, 48V, etc.). Consider if you require the optional temperature sensor for enhanced battery health monitoring, especially for lithium banks. If remote monitoring via smartphone is desired, remember that a VE.Direct Bluetooth Smart dongle is required and sold separately. Ensure you have adequate space for the flush-mount display unit (69x69mm front bezel, 52x31mm body). For series-connected battery banks, the midpoint voltage monitoring feature of the BMV-702 is highly recommended. Always refer to the official Victron Energy documentation for detailed installation instructions and the most current specifications. Compatibility with third-party components should be independently verified. ```
