    The 10 in 3210AN signifies it is a 100v controller.  Note that according to page 9 of the manual the 100v rating is at "minimum operating temperature" (presumably -25C according to page 25), and at +25C it is rated at 92v. 

    In series the panels would have a Voc of 134.61v.  It is common to include 20% margin which would be 161.5v, way more than the 92v/100v the controller is rated for.  I would run them in parallel or trade in for a 200v controller.

    Digression:  I assume the battery bank is 24v, or the controller would be brutally overpaneled.

    OK Thanks. Is there any controller do you suggest?

    I've never bought  200v controller.  I know epever (same brand you have) makes some, and Victron, etc.
