Poor battery connection.
The absorption voltage has been set to an
incorrect level (too low).
The float voltage has been set to an incorrect
level (too low).
The available charging time is too short to
fully charge the battery.
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.
The battery is

level (too high).
The float voltage is set to an incorrect level
(too high).
Poor battery condition.
The battery temperature is too high
(due to poor ventilation, excessively high
environmental temperature, or excessively
high charging current).
The charging current
Defective battery temperature sensor
drops to 0 as soon as

The battery is over-heated (+50°C)
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
1
Device is switched off because one of the
other phases in the system has switched off.
3
Not all, or more than, the expected devices
were found in the system.
4
No other device whatsoever detected.
5
Overvoltage on AC-out.
10
System time synchronisation problem
occurred.
14
Device cannot transmit data.
17
One of the devices has assumed 'master'
status because the original master failed.
18
Overvoltage has occurred.
22
This device cannot function as 'slave'.

Meaning:
Check the battery connections.
Set the absorption voltage to the correct
level.
Set the float voltage to the correct level.
Select a longer charging time or higher
charging current.
Reduce the charging current or select the
'fixed' charging characteristics.
Set the absorption voltage to the correct
level.
Set the float voltage to the correct level.
Replace the battery.
Improve ventilation, install batteries in a
cooler environment, reduce the charging
current, and connect the temperature
sensor.
Disconnect the temperature sensor plug in
the . If charging functions correctly after
approximately 1 minute, the temperature
sensor should be replaced.
Install the battery in a cooler environment
Reduce the charging current
Check whether one of the battery cells has
an internal short circuit
Cause/solution:
Check the failing phase.
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.
Check the failing unit. Check the communication cables.
Check the AC cables.
Should not occur in correctly installed equipment. Check the
communication cables.
Check the communication cables (there may be a short
circuit).
Check the failing unit. Check the communication cables.
Check AC cables.
This device is an obsolete and unsuitable model. It should
be replaced.
