Simple answer:
No
Complicated answer:
What you are showing are grid-tie inverters. Forget that. You have to get that all approved by the energy provider and done by professionals. For a grid-tie system it would make more sense to use all the panels and a full size inverter but I doubt the installers will even use your Ebay stuff.
If I understand correctly you want to charge a UPS which is already an inverter but with a battery.
So what you might want is to charge that battery.
If you can access that battery and connect it's terminals with one of these connected to your solar panel :
you are good to go.
If you want to run the UPS off-grid you need an external battery and an inverter capable of the power the UPS can handle, that would be very expensive.
Edit:
The batteries in a typical UPS are not very large. A standard PC might run 30-60 minutes. Even only a single 180W panel might be a bit overkill for them.
It might help if you explain why you want to do this.
