Ctrl+f and enter q715 in manual )
INV_OUT +400V 0.8V Q706, Q715, Q716 at least 1 part bad Q706 and
Q715/Q716 bad

It is IGBT. I dont have SURT3000. In APC SURT2000XLT IGBT- GP30B120KD-E
What type of Q705, Q718, Q717 ?

Q706 - gen4 IGBT UFST 600V 27A
Q715 - gen4 IGBT FST 900V 28A

for this case you can use HGTG10N120BND its 1200V, 35A...

q706 - gen4 igbt ufst 600v 27a
q715 - gen4 igbt fst 900v 28a

for this case you can use hgtg10n120bnd its 1200v, 35a...
