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...

Sorry I'm still confused as to what exactly the the quoted statement means
Each of us experience things a bit differently
Watts (DC) to me is very simple Volts x Current
A 500 watt PV array with the correct temps & lighting should come very close (efficiency is expected to be in the high/very high 90%, if not something is wrong)to supplying 35+ amps(to a 12Vdc nominal load requiring such current) if not then again something is wrong with the installation. I don't really care if it's a PWM or MPPT controller.
Not sure how we got onto PWM Vs MPPT
There are many flavors of each variety some good some NOT so good
