I think it’s some type of MLCC. If you look up variations of this inverter board, some have two MLCCs in the same location labeled C7 and C8. I know that some MLCCs can fail catastrophically if they crack and short circuit, may be what happened to yours.

If it’s part of an LC circuit the capacity and ESR will be important to match, but if it’s only a filter capacitor, you can typically drop in a high value cap to replace it without worrying too much about matching the values. If course you’ll want it to be rated for the voltage and temp.
