For a couple days been noticing higher than the 14.6 voltage,.....going to 15, and even 15.5,....I knew something was not right. The next day it was showing 16, then quickly went to 17+.......I quickl...

It is easy to have a spare PWM if you have a 12v array but not so ea$y to have a spare MPPT if you have a 24v array. EG Mr Wiz lost his MPPT but had a spare PWM, but he has a 12 array
I have a spare PWM controller having sold my 130w panel but can't use it with my 230w panel if the Eco-W goes bad. Another reason to have two 120s instead of a single 240. Could run the two in series for MPPT, but switch to parallel if needing to use the PWM.
