Interesting to see the double dies in the HY5012W.  Given that the blowups happen around 7.5kW, I think Solar Mike is right that it's more likely the FET's failed due to overvoltage than overcurrent.  I still wonder if potential anomalies (e.g. Miller shoot-throughs) that degrade the FET's over time could be the failure cause.
