[admiralslater]

Good morning from Bequia . I recently upgraded my solar system amd have installed e victron 100/30 mppt controllers.the factory preset is -16.20v/degrees c. What doesthis mean . Also I don’t believe it’s correct for 85 degrees c .
FYI, I am running firefly batteries

I have the 150/60, I assume it works the same as yours. There is no battery temp compensation that I am aware of in these equipments. Temp compensation is 16mV per °C, in order to protect the MPPT converter itself, nothing else. This is my understanding, I could be wrong.
