It might help if you state what made components blow up:
* How were you using the unit?
* What mode it was operating in (inverting, charging)?
* What was attached to it?
* What amount of power went through it?
* Did a fuse or circuit breaker trip?
* Was it caused by reversed polarity battery cables?
* Do any functions still work?
Looking at ads on websites, they make it appear that GYS products are sophisticated devices. Do they have safeguards to protect from mishaps?
You circled a small IC which does not carry much power, so it's probably part of the control section. It has tiny pins which require skill for anyone to desolder and then solder a new IC. The board appears to have a clear epoxy coating which makes repairs more difficult if not impossible. There may be additional components broken which need to be diagnosed.
Can you recognize the power carrying components? Do you know the theory how they work?
Can you find a schematic of a similar unit on the internet? Or a schematic of a control system?
You may be able to construct a homebrew control system and thus gain back some utility of your unit.

Thanks for contacting me
I bought it already in broken condition so is difficult to say what happened with charger I just need to get schematic and parts list and I will replace all burned parts
