Just asking for some confirmation of what I believe I am seeing here,
This data is showing the quattro temp derating in AC coupled mode correct? The stepping of the AC output frequency and corresponding PV inverter yield coincides with the temperature warnings. The co-located MPPT yield is not throttled, the batteries are at ~65% (LA) and are in absorption, however the throttling is seeing the voltage not holding.
To me the device looks like its heat saturated, The PV Inverter reductions are too symmetrical and correspond with the temp warnings to be clouds.
It would be great if there was an indication the unit was derating or a internal temp sensor to verify.
EDIT
So have a little more info from the site, the fans in the unit are slowly winding up then try to go to full speed and shutoff, this happens at exactly the same time the unit derates.
This leads me to believe that the power bus that runs the fans is exceeding its current and shutting down. Maybe by a self resetting fuse?
This unit runs a small island so sending the unit away will have problems.
It is possible for victron staff to look at any more internal data via the console to possibly determine the issue?
