I have a Victron Quattro 5000 that runs off of 24 volts in TV live truck. In our current unit the capacitor bank between the heat sinks have completely blown up. We have purchased a new one, but before installation, looking for info on what circuit those capacitors are associated with so we don't blow up the new one.
Usually that is caused by high DC ripple. Upgrade your battery cables. 95mm² x2. Check you do not have too many connections between the inverter and battery. And make sure the battery you have connected sized for the job.
Also make sure the balance between battery capacity and inverter is correct. the inverter needs >250A so you need 500Ah lithium or 1000Ah lead acid
