Classic 150 and panel voltage

[firerescue712]

I am looking at replacing my Rogue 3024 with a Classic 150.  The panels are various watts, but the VMP's are within 10% +/-.  They are run parallel 24 volts.  The voltage loss is under 3%.  Will i have to increase the voltage to work with the Classic 150?  Or can I keep the current setup and add more panels at 24 volts?  The Classic graphs do not show watts under 90.  I am trying to figure out how many 24v panels I can run to max out the Classic.  Once I get enough panels with IMP's of 10% +/-, I will rewire the like-type panels into 90 volts, if needed.  Thank you.
