It would help if you’d share your SketchUp model so we can see how you have things set up.
hi Dave my model is to big to share… is there any other solution?
thank you
Upload it to DropBox or Google Drive or WE Transfer and share the link.

is it ok?
No. You need to grant permission so we can download your file. Also, you’ve marked your post as the solution. That’ll stop other folks from trying to help you because they’ll think your problem is solved.

Have you added any V-ray lights? There don’t appear to be any in the components list that I can see.
You have a lot of exposed back faces in your model. Look at your cabinets for example.Those will not render correctly. You should correct those faces.
There’s an awful lot of unused stuff in your model. Purging unused once in a while would help.
This purge reduced the file size by about 66%.
And incorrect tag usage which might have come in with components from the 3D Warehouse.
All edges and faces should be created and remain untagged.
ok thank you for all info. May i ask u for your help ( I’m willing to pay for the service ). Im using sketchup several month - so its pretty new all this for me. But I’m satisfied 
Are you asking me to repair your model? I’ve purged it and did some cleanup but I’m afraid I don’t have time right now to do more with it. I’m sorry.

still nothing… i would like to know where is the main problem, because second pic is first render its not perfect but its least something and then suddenly I have now only black one 
Turn on shadows and you’ll see that at UTC +07:00 it’s still dark. Try as you see in my image with +09.:45.

First of all, make sure that you have the model created correctly in SketchUp. Dave has already shown you the main changes you need to make.
Then go to Chaos site and watch the tutorials for V-Ray, starting with basics
If I change the UTC to +12:00, the rendering will look like this
So when I tried it with your settings…this is what I got:
Then I reset all of your settings in the Asset Editor to back to ‘Default’. And under ‘Camera’ I enabled ‘Auto’ for the ‘Exposure’.
Lastly, I turned on your ‘Display Correction’ in the Frame Buffer (open the right panel to find that). And added a new ‘Exposure’ layer where I then turned your ‘Highlight Burn’ down.
Still a lot of work to do to help improve this rendering but at least this should get you back on track.
