Smart BatteryProtect 12/24-220A power controller – is a reliable device for automatically disconnecting all consumers when the battery charge drops below a set limit. Thus, the device guarantees the protection of batteries from deep discharge, which can damage them. In addition, the module can act as a main switch for convenient remote turning on or off of the entire power system. The presence of an integrated Bluetooth radio module makes it possible to quickly and comfortably configure any trigger thresholds from a smartphone screen via the VictronConnect utility.
Smart BatteryProtect – is not an ordinary voltage relay, but a smart load management node. The module works perfectly in tandem with VE.Bus BMS, has special profiles for lithium-ion batteries, consumes minimum energy in standby mode, and protects the system from overvoltages.
Main advantages of the Smart BatteryProtect controller
- Intelligent detection of connected network voltage (12V or 24V)
- Wireless settings management via VictronConnect (the radio channel can be disabled by software)
- 9 built-in protection profiles plus a free manual configuration mode
- Perfectly compatible with LiFePO₄ lithium cells – thanks to integration with VE.Bus BMS
- Optional use as a powerful charging switch
- High-precision overvoltage protection barrier with the ability to adjust with an accuracy of 0.1 Volts via the app
- Modest own consumption: within 0.9–1.4 mA
- Quiet and intrinsically safe operation (based on MOSFET transistors, which eliminates the presence of moving contacts)
- Use of time delays for triggering, eliminating false alarms due to short-term voltage drops
- Built-in short circuit protection of the alarm interface
- “Instant Readout” mode – allows viewing key parameters in the app without establishing a full Bluetooth connection
