Hello, I have a Quattro 12/5000/220 with firmware 497. Even under very low load conditions, the fan starts more or less regularly, runs for approx. 5..10 minutes, then stops.
Ambient temperature is below 20 degrees Centigrade and the air coming out of the quattro is cold all the time.
Does anyone (maybe victron staff ;-) know what exactly is the fan control algorithm? What causes it to start?
I know there have been issues with noisy fans and associated fixes in new firmware, but afaik that only concerns newer devices with pwm-controlled fans. My device simply turns the fan on or off.
I also have a Cerbo attached to the unit, is there anything on the DBus/MQTT to help me find out the reason?
