victron energy BatteryProtect BP48/BP100 Instruction Manual
Installation
-
The BatteryProtect (BP) must be installed in a well-ventilated area and preferably close (max 50 cm) to the battery (but, due to possible corrosive gasses, not above the battery!). Voltage drop over a long or undersized cable between the battery plus and the BP may result in unexpected shutdown of the BP.
-
A properly sized fuse must be inserted according to local regulations in the cable between the battery and the BP.
-
The BP is designed to allow current to flow from IN (battery) to
OUT (load) terminals only.
Reverse currents from OUT to IN terminals are strictly forbidden, and will damage the device. If you wish to use the BP as a disconnection for a charge source, you must orient the unit in the system so that the current is flowing in the intended direction, IN to OUT. -
The short circuit protection of the BP will be activated if you try to directly connect loads with capacitors on their input (eg inverters). For that use case, please use the BP to control the remote on/off switch on the inverter, instead of disconnecting the higher power DC line.
-
Use a 1,5 mm² wire (included) for the minus connection, which should be connected directly to the battery minus. No other equipment should be connected to this wire.
-
The BP will automatically detect the system voltage after connection of plus and minus to the battery. During voltage detection the 7 segment display shows a series of flashes between the top and lower part.
-
Do not connect the load output until the BP has been fully programmed.
-
A remote on-off switch can be connected to the two pole connector (see figure 1) or between pin 2-1 of the two pole connector and the battery plus.
-
A buzzer, LED or relay can be connected between the alarm output and the battery plus (see figure 1). Maximum load on the alarm output: 50 mA (short circuit proof).
Load disconnect events and alarm output options
Buzzer or LED mode (buzzer or LED connected to the alarm output):
- In case of under voltage, a continuous alarm will start after 12 seconds. The BP will disconnect the load after 90 seconds and the alarm will stop.
- In case of over voltage, the load will be disconnected immediately and an intermittent alarm will remain on until the overvoltage problem has been corrected.
Relay mode (relay connected to the alarm output):
- In case of under voltage, the relay will engage after 12 seconds. The BP will disconnect the load after 90 seconds and the relay will disengage.
- In case of over voltage, the load will be disconnected immediately and the alarm output will remain inactive.
Li-ion mode:
- Connect the load disconnect output of the VE.Bus BMS to pin 2-1.
The load is disconnected immediately when the load disconnect output of the VE.Bus BMS switches from ‘high’ to ‘free floating’ (due to battery cell under voltage, over voltage or over temperature). The under voltage thresholds and alarm output of the BP are inactive in this mode.
Programming
When switched off (remote open), the BP can be programmed for the desired
voltages and modes by connecting the PROG pin to the ground. Please see the
programming table.
The display will first step through the shutdown and restart voltages.
Disconnect the PROG pin when the desired voltage is displayed.
The display will confirm the chosen voltage and default mode (A) twice.
Reconnect the PROG to ground if another mode is (b or C) is required.
Disconnect when the required mode is displayed.
The display will confirm the chosen voltage and mode twice.
Operation
There are 4 possible error modes, indicated by the 7 segment display:
- E 1 Short circuit detected
- E 2 Over load or over temperature
- E 3 Under voltage
- E 4 Over voltage
After 5 minutes the error is no longer displayed to reduce current consumption.
The decimal point of the 7 segment display is used for status indication:
- On solid: the BP attempts to activate the output
- Flash every 5s: output is active
- Flashing every 2s in Li-ion mode: output ‘connecting’
Remote control and short circuit
- The BP will connect the load 1 second after closing the remote contact.
- The BP will disconnect the load immediately when the remote contact is opened.
- When in Li-ion mode the BP will connect the load 30 seconds after the remote input of the BP has been pulled high by the VE.Bus BMS. This delay increases to 3 minutes in case of frequent switching.
- In case of a short circuit, the BP will attempt to connect the load every 5 seconds. After two attempts the display will show E 1 (short circuit detected).

APPENDIX
Error Codes
E1: Short circuit
Short circuit protection is activated in the event of a short circuit, an
overload condition or excessive inrush current – such as when attempting to
directly power an inverter
- Check for a potential short circuit condition
- Confirm that the load current draw does not exceed the BP current rating
- Use the BP to control the remote on/off switch on loads with high inrush currents, rather than directly powering/disconnecting the DC supply
- Check for loose/high resistance connections and ensure that appropriate gauge wiring is used in the installation
E2: Over temperature
Over temperature protection is activated in the event of excessive internal
temperature
- Confirm that the load current draw does not exceed the BP current rating
- Check for loose/high resistance connections and ensure that appropriate gauge wiring is used in the installation
- Do not install the BP unit in a location exposed to high temperature or radiant heat – relocate BP to a cooler position or provide additional active cooling.
E3: Under voltage
Under voltage protection is activated in the event that the input voltage
drops below the under voltage limit selected for 90 seconds
- Switch off/disconnect loads and recharge the battery
- Check charging system and battery for proper operation
E4: Over voltage
Over voltage protection is activated in the event that the input voltage
exceeds 64 V
- Confirm the configuration of all charging devices in the system – particularly system voltage and charge voltage settings
- Check charging system for proper operation
- Confirm BP system voltage configuration is correct
