I cannot see your inverter (5500) on the mastervolt site:
Solar Inverters 1-10 kWp | Mastervolt Solar energy solutions
Which one is it?
Yes, that was a strange one, I was never able to find it on their site, however, when I plug in masterlog software, it reports it as XS6500 Though all the paperwork refers to 5500
