Right, even the 600v charge controllers tend to be set up for 48v battery banks because a 600v DC shut off switch would be so costly it would start to make the cost of the wire to run between the panels and the battery bank seem cheap!

MPPT (maximum power point tracker) allows higher panel voltage that charges a lower battery voltage.
