Hi there
I have a 10 year Victron Energy Quattro 24V 5000VA (Model QUA245020000) that I am attempting to repair. It recently blew a MOSFET and in stripping it back to swap out the blown transistor I noticed that the capacitors were beginning to bulge. I have a couple of quick questions:
1/ In a unit 10 years old which has had non continuous use with significant periods of time idle is it normal to see some swelling of the capacitors and is this a sign that they should be replaced?
2/ Is it likely / possible that the capacitors caused the MOSFET to fail?
If anyone has some experience of this situation and could offer some advice that would be very much appreciated. While I have the unit stripped back I don't want to miss the opportunity to get in front of a future potential problem.
Many thanks, alex
