Depending on the C-rate, it could take hours to get to 14.8v. (Better safe, than sorry).

The unquoted part of what I posted was about the MS MPPT45 and it's derating at 45A as per the specs. At 45A it's not going to take hours to get to bulk charging.

Correct MS is better safe than sorry by protecting the controller against more than 45A output and over paneling.

Less quality controllers well.....
