Victron energy MultiPlus-II 48/3000/35-32 230V GX Manual De Instrucciones página 18

The battery is
overcharged.
The charging current
drops to 0 as soon as the
absorption phase
initiates.
16
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 absorption voltage is set to an
incorrect level (too high).
Poor battery connection.
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).
Defective battery temperature sensor
The battery is over-heated (+50°C)
Reduce the charging current or select the
'fixed' charging characteristics.
Set the absorption voltage to the correct
level.
Check the battery connections.
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 MultiPlus-II GX. 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
