Lost microinverters due to power surge. How common is that?

There is some history on the forum if you search Enphase Microinverter Mass Failure.

, was your cheap surge suppressor a breaker type surge suppressor?

Do you have quality surge suppressor at your panel or preferably on the circuit where the microinverters are hooked to?. I lost a string inverter once on a windy day. The top of the pole snapped off and somehow shorted the distribution voltage with the household voltage nearby. Mmy neighbor had major damage. I had a cheap surge suppressor. I lost the inverter and one other device but my other inverter rode through it. I now have Midnight Solar SPDs on my main panel and one the incoming lines from the arrays. They claim their clamp voltage is lot lower than competitors.

Our grid-tied system was installed on March 2017. 23 panels with S280 Enphase micro-inverters. It was OK until a windstorm caused some power outages in the area (not the first time we have lost power, we're in a semi-rural area) and afterwards we noticed some micro-inverters were no working. Long history short it was determined that there was a power surge that fried the micro-inverters and we are now waiting for the homeowners insurance to approve the claim to replace the micro-inverters.

I haven't been able to find another case similar to ours, but I can't believe we are the only ones. Has anyone had something like this happen?
