Battery voltage not allowed

W-B01

Low cell voltage

Low cell voltage

Charge the battery or reduce the load to prevent an imminent system shutdown.

W-B02

#105 or #106

Reduce the current to prevent an imminent system shutdown. Do this by reducing the load or by turning loads off.

W-B03

#101

High BMS temperature

Check the ambient temperature and check if the BMS fans are running. If the fans are running, reduce the ambient temperature. If the fans are not running, contact your Victron dealer.

W-B04

#112

Warning bad contactor

Reduce the current to prevent an imminent system shutdown. Do this by reducing the load or by turning loads off. Contact your Victron dealer.

W-B06

-

Load will disconnect

The loads will be turned off in 30 seconds if fault is not resolved. For example low battery voltage. This warning is always in combined the reason why the load will disconnect.

The loads are turned off via the ATD contact and/or via the GX device.

W-D01

#221

Communication with distributor A lost

Check the cable between BMS and Distributor.

W-D02

#222

Communication with distributor B lost

Check the cable between BMS and Distributor.

W-D03

#223

Communication with distributor C lost

Check the cable between BMS and Distributor.

W-D04

#224

Communication with distributor D lost

Check the cable between BMS and Distributor.

E-B09

#09

Battery voltage not allowed

The battery voltage is too high or too low. Check the battery voltage and check the battery settings in the VictronConnect app.

This error occurs when the battery voltage is outside all system voltage ranges (9V > Vbat > 60V)

E-B11

#11

Hardware error

Contact your Victron dealer.

E-B25

#25

Pre-charge error

The load resistance is too low to pre-charge the loads. Disconnect or reduce some DC loads.

E-B26

#26

Contactor error

Contact your Victron dealer.

E-B34

#34

Wrong system voltage

Check battery voltage settings in the VictronConnect app.

E-B35

#35

Pre-charge timeout

The load capacity is too high to pre-charge. Disconnect some DC loads.

E-B36

#36

ATC/ATD failure

Check ATC/ATD wiring and make sure that all loads and chargers are controlled by ATC or ATD.

E-B119

#119

Settings data lost

Settings data is corrupt. Go to the settings page and reset to defaults.
