The MSP is Cutler-Hammer and the main breaker is 200A. I need to know if the busbar is 225A or 200A to check the max PV system size. When looking at the label, the 4 model number made me confused. It looks like below:

MBED3042B200BF
MBED3042B200BF6
MBED3042B200PV
200 AMPS MAX
( SEE MAIN CIRCUIT BREAKER RATING)

MBED3042B225BF
225 AMPS MAX
(SEE MAIN CIRCUIT BREAKER RATING)

The main breaker is 200A, so the busbar is also 200A?
 
Seems like Eaton is lazy and using one sticker for 4 panels, you'll need to peck and hunt for the actual model number of the panel your looking at.
Perhaps post some photos.
At least the sticker is still there.
 
I would not be surprised to find that the same busbar is used in all of the panels. However the ampacity rating of a panelboard often involves more than simply the bus bar size.

I believe you need to get an answer from tech support as to the amount of PV which can be added.
