Battery Monitor BMV-702

is an advanced device used to monitor battery charge status. Its main function is to track energy consumption and monitor remaining discharge time, making it an indispensable tool in power systems. BMV-702 allows for simultaneous monitoring of two batteries, making it an ideal solution for both camper owners and users with more extensive power systems. The device is equipped with programmable alarms that warn of low charge levels or excessive voltage, helping to avoid failures and power management problems.
Thanks to advanced algorithms, BMV-702 precisely determines the battery's operating parameters. The Puekert algorithm, which is part of the software, accurately calculates the state of charge, taking into account current consumption, temperature, and battery age. The user has full access to key information such as voltage, ampere-hour consumption, and remaining discharge time. The device is exceptionally flexible, as one of the inputs can be programmed to monitor the second battery's voltage, temperature, or midpoint voltage. This makes BMV-702 is an extremely versatile monitor, adapting to the specific needs of various power systems.

High precision and ease of use

One of the greatest advantages Victron Energy BMV-702 is its precision. The device measures current to 0.01 A and voltage to 0.01 V, ensuring extremely precise monitoring of battery performance parameters. This allows users to be sure that their power systems are operating optimally. Additionally, the monitor is equipped with a VE.Direct port, which allows for easy data exchange with a computer, making battery monitoring even more convenient. The kit also includes all necessary installation components, such as a shunt, cables, and mounting accessories, making installation quick and hassle-free.
BMV-702 It also features alarms that notify you of critical conditions, such as low battery or overvoltage. Additionally, a programmable relay allows you to automatically shut down critical loads or start a generator when necessary. This makes the monitor not only a monitoring tool but also an integral part of the power management system.
