Multiplus | Maximum power without engaging the fan

Hi,

Currently I have a small MultiPlus 12/500/20 and the internal cooling fan starts when an output power reaches about 100-150W.

I’m looking to buy a larger MultiPlus, probably MultiPlus-II GX 48/3000/35-32 or 48/5000/70-50,
and trying to choose a model to run without engaging the fan if possible.

Can anyone share at what load does the inernal fan start in these models:
MultiPlus-II GX 48/3000/35-32
MultiPlus-II GX 48/5000/70-50

FYI
There is a assistant (silence fan) you can install on your MP who “disables” the fan.
It automatically throttles down the output when temperature becomes to high.

I have a MP 48/500/70 and I set the max charge/discharge limit during the night to 1000W to prevent the fan to kick in. Using a simple nodered flow.

Thank you for the insight!

I’ve read about “Silence fan” before, but the wording of this message

was a bit vague (no concrete specs),
and I wasn’t sure how higher temperature (without a fan) can affect the Multiplus’ longevity,
so didn’t risk to use it for a prolonged time.


Does anyone have any info about the fan in the MultiPlus-II GX 48/3000/35-32?

I’ve hoped to find something like this PC PSU chart:

or at least something like “The fan starts when the output power reaches XXX W (at YY °C)”.

Can anyone from Victron provide such specs?

I suppose that this can be changed in the firmware later(?), but what about the current threshold?
