I just powered my new dc-dc Victron 12-12-30 (non-isolated). I measured the voltage on the IN and GND terminals, and this is 12.5V (correct, like my engine battery), however the Victron Connect app shows me an input voltage of 13,5V, which is obviously incorrect (?).Is there a plausible reason for this? note that I have not connected the service battery at the moment, so the Victron is disconnected from loads. Could this be the reason?
Note: the output seems to work and the dc-dc switches off when I turn off the engine and it reaches the set voltage (but only taking into account the voltage difference between the real voltage and the one he read)
