Adjusting inverter output in solar power system

[Martin 1]

Hi guys,
Newbie here
I have basic knowledge of electricity
Try to find a solution for a solar system that is grid tied and I do not want to deliver back to the grid
All of the grid tied inverters are delivering back to the grid if you don't use all
This is not allowed by my power provider
I was thinking about a system that will reduce the output of the inverter
Is this possible?
Want to make that like reading an input from the usage and let that control the output from the inverter
What you all think
All comments are welcome

There are a few options:

1. Make sure your load never falls below the maximum output of the inverter
2. Use something other than a grid-tie inverter.

Steve thanks for your reply
Option 1 is very difficult because my load varies from 0.5-10kW
2 is maybe better then was thinking of mini inverters that will switch on with the load increase
Then I have to find a way to measure the load and make switch points with contactors or something like that
Could measure the load with CT's then I need to get a electronic circuit
Is this possible?

It's a difficult problem. What you essentially want to do is to use solar power when it's available and to supplement it with grid power, but without feeding the excess solar power to the grid.

If you find a way, let me know. (OK, there are ways, but if you find an *efficient* way, let me know)
