Rolls 6 CS 21P Max charge current

[jtbartlett]

As listed from the manufacturer the min charge current is 34A and max charge current is 68A. My 4125w (5strings of 3 @ 275W) solar panel array battery charging current will be 71.6A. How critical is the max charge current rating? Will I be able to set the max charge current lower in the classic 150 charge controller? Sorry if these are solar beginners questions...I am trying to not make any critical mistakes.

Don't think you have to worry about the 3.6 amp excess, you not going to get that much current most of the time of the day and you will have other load on the system to take some of the current. Even if you don't have any load, when the voltage reach to absorb stage the current will cut either by the high voltage or the battery resistance.

Sometimes a number of smaller (sub-critical) mistakes can also add up to become critical!
