Hello,
I installed an external temp sensor to cool the controller through fans in case it reaches 40°C.
Therefore I noticed that the internal temp sensor always shows 6° too much, no matter if it's day or night.
Yes, I double checked the external sensor electronics with another temp meter - they show the same...
Is there any way to recalibrate the sensor of the controller to get accurate measurements?
Thanks a lot in advance and happy sun ray hunting,
Flow
No there is no way to calibrate this as far as I know.
suspect its measuring the internal temp and you are measuring the case temp
Thanks for replying!
I measure at the upper right corner of the heat sink.
And as stated above: Even at night (when all cooled down equally) it's the same difference...
Therefore I noticed that the internal temp sensor always shows 6° too much, no matter if it's day or night.
Pretty sure that you can not access the internal temp sensor of a Victron MPPT.
Your MPPT can report external sensors though..
This is unfortunate to read, tho I still think that there's a way to calibrate since it's all supported by software...
