Hi, I've installed a cooling fan in my camper to cool the Orion TR Smart during the drive. I've connected it successfully to the Cerbo GX relay 1. The relay is set to Gen/Start Stop. I've defined the relay to start when the current that draws in the battery is above 20 A.
Manual Start works but the automation does not close the relay when the Orion TR Smart charges the battery with 30 Amps. Do I have a logical mistake here?

The generator start/stop logic would NOT count the charging current as a "load" so the "generator" would not run.
Would it make any sense to simply connect the fan to a switched 12 volts from the ignition switch so the fan runs whenever the ignition switch is in the on position? It does mean the fan will continue to run even after the batteries are charged and the Orion output is close to zero.
You could also sense Orion heat sink temperature and use that to control the fan. Something like this:

Might be better solutions. The above is just the first example I came across.
Just wondering if @Kstyler got this working with the recent firmware update ? I'm looking to do the same thing
Hello, I found another solution. I've added a temperature switch that closes the circuit at 45 degrees Celsius. Now the fan cools the Orion when it reaches these temperatures.
Hi @Kstyler
could you explain your solution to power the cooling fan please, Iv added a temp sensor to close the relay when the temp is 45 degrees and open again at 30 degrees as a test. Where have you got the power for the fan, are you wiring directly to the Cerbo?
