The Victron BatteryProtect 12/24V-100A was designed to be used either as a stand-alone device or as part of a control system for the Li-ion battery bank. This battery protection accessory is a solid-state relay and can be utilised to disconnect the load from a battery in the event of over discharging. It is controlled internally by programmable parameters for low and high voltage or when used with Lithium Ion batteries it is controlled remotely by the VE Bus Battery Management System
The Victron BatteryProtect 12/24V-100A automatically detects system voltage (12 or 24 volts), and it is designed to disconnect the battery from non-essential loads before it is completely discharged to prevent damage to the battery, or before there is not enough power left in the battery to activate the engine.
By using the seven-segment display to show which setting has been chosen, this battery accessory can be programmed to engage or disengage at several different voltages. For Li-ion batteries, the BatteryProtect can be controlled using the VE.Bus BMS. The Ultra-low current consumption is important in case of Li-ion batteries, especially after low voltage shutdown. To prevent damage to sensitive loads due to over voltage, the load is also disconnected whenever the DC voltage exceeds 16V or 32V. This is a solid-state device using MOSFET switches instead of relays and so is ignition protected.
The alarm output is activated if the battery voltage drops below the pre-set disconnect level for more than 12 seconds. Starting the engine will therefore not activate the alarm. The alarm output is a short circuit proof open collector output to the negative (minus) rail, max. current 50 mA. The alarm output is typically used to activate a buzzer, LED or relay. The load will be disconnected 90 seconds after the alarm has been activated. If the battery voltage increases again to the connect threshold within this period (after the engine has been started for example), the load will not be disconnected. The load will be reconnected 30 seconds after the battery voltage has increased to more than the pre-set reconnect voltage.
