Victron BP-220 Battery Protect, 12V/24V-220A

Victron BP-220 Battery Protect (12/24V)

The BatteryProtect battery protection disconnects the battery from insignificant loads before it is completely discharged (which would cause its destruction) or until it still has enough capacity to start the engine.

• Disconnecting appliances as protection against deep battery discharge
• Maximum load current 220 A

Automatic 12/24 V setting
BatteryProtect battery protection automatically detects the voltage in the system.

Easily programmable
BatteryProtect protection can be set to engage/disconnect at several different voltage levels.
A seven-segment display shows which setting was selected.

Special setting for Li-ion batteries
In this mode, BatteryProtect protection can be controlled via the VE.Bus BMS bus.

Very low energy consumption
Low consumption is very important for Li-ion batteries, especially after shutdown at low voltage. For more information, please see the technical specifications for Li-ion batteries and the VE.Bus BMS bus user manual.

Overvoltage protection
In the event of an overvoltage causing possible damage to sensitive devices, the devices are disconnected if the DC voltage exceeds 16 V, or 32 V.

Spark-proof
It does not work with relay elements, but with MOSFET transistor switches, so sparking does not occur.

Delayed alarm output
The alarm output is activated in case the voltage on the battery drops below the set value for more than 12 seconds. Starting the engine therefore does not activate the alarm. The alarm output is an open collector output to the negative bus, max. current 50 mA. This alarm output is typically connected to a buzzer or to light signaling.

Delayed load disconnection
The load is disconnected 90 seconds after the alarm has been triggered. If during this time the battery voltage rises to the “reconnect threshold level” (e.g., during engine starting), the load will not be disconnected.

BatteryProtect battery protection is unidirectional i.e., current can only flow from the “in” input to the “out” output. Reverse current flowing from the “out” output to the “in” input is not allowed and will damage the device.
