Victron energy Quattro 12 3000 120 - 50 50 - 230V Anleitung Seite 23

The battery is overcharged. The absorption voltage is set to an incorrect 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 drops to The battery is over-heated (>50°C)
0 as soon as the absorption
phase initiates.
Defective battery temperature sensor
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.
Install the battery in a cooler environment
Reduce the charging current
Check whether one of the battery cells has an internal
short circuit
Disconnect the temperature sensor plug in the
Quattro. If charging functions correctly after
approximately 1 minute, the temperature sensor
should be replaced.
