Does solar inverter is intelliegent one?

I have doubt for example if my load consume 12kw per hour and if my solar panel produces 8kw/hr then what will be choice of inverter to satisfy the load.
1) does it take 8kw from panel and remaining 4kw from main
OR
2)it takes all 12kw from main

A grid tied inverter (GTI), also called a grid-interactive system, will produce the maximum power that the PV array is capable of supplying at the moment and fee that into your electrical system.
If the output is lower than your consumption, the excess comes from the power company (POCO) through the meter.
If the output is higher than your consumption, the excess is fed back through the meter to POCO.
This requires an interconnection agreement between you and POCO, and a meter which is configured to count down when power is flowing out. If that is not done, you will be billed for any power you send back as if you were using it instead.

Well, according to my experience in solar technology, solar inverters are intelligent one as well as cost efficient, but I still doubt their overall efficiency.
