This summer we had a customer with a single CPI experience 3 OV events over the course of a few months.
In one instance, this took out the CPI, AP, glass panels, backup EFIS battery, defrost fans and split the case on the main battery.
This airplane had a crowbar setup on the alternator and OV protection on the VPX Pro as well.
We don't know how high and for how long this event lasted but we think it was over 60V based on what fried.
I'm interested to know what others have experienced. Did your OV kick in and save the day or did you damage any electrical components? If anyone has any data logged showing the voltages reached and duration, that would be useful too.
