Poor battery connection. Check the battery connections.
The absorption voltage has been set to an
incorrect level (too low).
Set the absorption voltage to the correct
level.
The float voltage has been set to an incorrect
level (too low).
Set the float voltage to the correct level.
The available charging time is too short to
fully charge the battery.
Select a longer charging time or higher
charging current.
The absorption time is too short. For adaptive
charging this can be caused by an extremely
high charging current with respect to battery
capacity, so that bulk time is insufficient.
Reduce the charging current or select the
'fixed' charging characteristics.
The battery is
overcharged.
The absorption voltage is set to an incorrect
level (too high).
Set the absorption voltage to the correct
level.
The float voltage is set to an incorrect level
(too high).
Set the float voltage to the correct level.
Poor battery condition. Replace the battery.
The battery temperature is too high
(due to poor ventilation, excessively high
environmental temperature, or excessively
high charging current).
Improve ventilation, install batteries in a
cooler environment, reduce the charging
current, and connect the temperature
sensor.
The charging current
drops to 0 as soon as
the absorption phase
initiates.
Defective battery temperature sensor Disconnect the temperature sensor plug in
the . If charging functions correctly after
approximately 1 minute, the temperature
sensor should be replaced.
The battery is over-heated (+50°C) Install the battery in a cooler environment
Reduce the charging current
Check whether one of the battery cells has
an internal short circuit
7.2. VE.Bus error codes
A VE.Bus system can display various error codes. These codes are displayed on the front GX display screen.
To interpret a VE.Bus error code correctly, you should refer to the VE.Bus error codes documentation
https://www.victronenergy.com/live/ve.bus:ve.bus_error_codes.
Code Meaning: Cause/solution:
1 Device is switched off because one of the
other phases in the system has switched off.
Check the failing phase.
3 Not all, or more than, the expected devices
were found in the system.
The system is not properly configured. Reconfigure the
system. If the error persists, possible communication cable
error. Check the cables and switch all equipment off, and
then on again.
4 No other device whatsoever detected. Check the failing unit. Check the communication cables.
5 Overvoltage on AC-out. Check the AC cables.
10 System time synchronisation problem
occurred.
Should not occur in correctly installed equipment. Check the
communication cables.
14 Device cannot transmit data. Check the communication cables (there may be a short
circuit).
17 One of the devices has assumed 'master'
status because the original master failed.
Check the failing unit. Check the communication cables.
18 Overvoltage has occurred. Check AC cables.
22 This device cannot function as 'slave'. This device is an obsolete and unsuitable model. It should
be replaced.
