Converter Fried

So I fried my converter (50 amp wired to 30 amp plug)and it no longer charges my batteries.
Killed a box fan and at least one 15 amp breaker on my panel. Everything else seems to be fine.

I'm in the process of replace/upgrading the converter but I have a question: Why do I have a 55 amp converter for a 30 amp system?

Do I replace with another 55 amp converter or buy a 30 amp converter?
The wiring is plug n play so I feel I can tackle the installation I just don't want to put in the wrong converter for my coach.

I tried doing a search and nothing seemed to address this issue.
Thank you in advance

    The 55 amps is the output of your converter. It will provide 55 amps of 12-volt output which will either charge your batteries or run your lights. The 30-amp system you are referring to is the AC input for your unit. The 30 amps is at 120 volts and powers your air conditioner, microwave, 120 volt outlets and your converter. The converter itself only uses a couple of amps of AC power.

    I'm looking at buying a WFCO Deck Mount Converter/Charger – 55 Amp
    #58324 to replace my old one. Seems to have great reviews.
