!!!!!!!!!!!!!!!No, we can't help you without a model number. Even then
there's a pretty slim chance. Most re-branders of Chinese garbage such as
"Sundox" don't want or expect these units to be fixed. They are generally
of the poorest quality, from design to component selection to manufacturing
they are designed to be disposable. !!!!!!!!!!!!!!!!!!!!!!!!!!!


!!!!!!!!!!!!!!!!!!!And, by the way, using those exclamation marks is both
pointless and annoying.!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Yes. Learn how to use the ! key. To fix the invertor, you could test
the output devices first, most likely culprits. A repair manual is
proably not what you'll need, and may well be unavailable.

One transistor is exploded and not readable

Who has the numbers of the transistors

if the big transformer is exploded then replacing it should work.
disconnect the transformer from the circuit. connect two 12v bulbs
( or LED in series with 1k resistor ) with one end of each bulb
connected to the center tap wire and other to end terminals.turn on
the circuit and if the bulbs glow then the circuit is ok.

these days transistors are not used in the output stage of inverters.
MOSFET or IGBT are used.
