Best Way??

I recently tested my Canasdiansolar 220w in subfreezing temperatures, The voltage shot to over 40v for a few minutes until the sun warmed the panel. After that it stayed at 37v. It is rated foe 36.6v.
Otherwise the OPs serial/parallel panels are within the CC capability. It may rarely derate to 60A output and that would require very favorable solar conditions.
