sadly the part dosent seam to have a name on it even before it blew up:

but its connected to pin1 and pin3 of the IC so maybe the datasheet can help you https://www.meditronik.com.pl/doc/plusik/cxa_l0624_vjl.pdf

Edit: Found a similar PCB with 2x that component

makes me think its probably a capacitor

edit edit: found another related board where the element at least hast text on it

"M104 3M62" not sure what that is tho

    I probably won't be able to identify it, but including the name of the thing it's a part of along with a model number would help.

    SMT Capacitor

    See the thick traces?

    It's part of the power-section, which helps narrow-it-down, some..

    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. Of course you'll want it to be rated for the voltage and temp.

    Solid state relay? With like a heat sink on top?

    Is it a 3-terminal device? You may have to desolder it to find out. That also lets you poke around with the insides (hollow? layers?)

    Probably a capacitor, either 2 terminal or 3 terminal. I was originally thinking GDT but it looks like even the SMD varieties are mostly cylindrical shaped rather than rectangular prism.

    looks like a power inductor

    I think this is some sort of surface mount fuse.

    Don't quote me on that as fact though.

    @la508
    i found an image of a different version of the same product i think,
    it seems like this one has some red components that look like film capacitors in place of that blown smd thing

    Looks kinda like an un-encapsulated, surface-mount polyester capacitor e.g. https://dir.indiamart.com/items/kemet-f161zs104k630v-polyester-film-capacitor-surface-mount-s98697.html

    They don't generally explode like that though unless they see overvoltage.
