Inverters in database with same max DC voltage as max MPPT DC voltage?

Hey, when modeling a specific system configuration, we came across a very low kWh/kW yield. Everything appeared to be in order, in that the correct models for module and inverter (in this case the Northern Electric: BDM-300X2) were selected, and system design was all in order.

For this inverter the max MPPT voltage is 48V but the maximum input voltage is 60V. It appears in the database to be set to 48V for both max DC input voltage and max MPPT DC voltage, which we believe is causing an error in modeling the kWh produced by the system.

This isn't an issue we've come across with to date, is it possible the database was refreshed with incorrect values for Max DC voltage? It appears to be equal to Max MMPT DC voltage for the majority (but not all) inverters on the list.

Thanks!
Dave
