Hello I’m having some trouble with a solar inverter.

Accidentally applied higher voltage than rated, TVS diode blew up doing its job and the equipment pcb sustained some damage.

i got the design schematics and have found fault at BOS 2-1 TVS diode, C73, R81, R77 and BOS 2-1 TVS Diode,C8 , R55 , R33

also C88 and C109 are blown.

What I am asking of you guys is if in your experience this kind of damage is worth repairing? Or there is likely some deep damage I’m not aware of
