Many inverters have the option to zero-sell (no export to the grid) but you need an additional CT on the main service conductors so the inverter can monitor the loads and ramp down production if it starts to get close to producing more than the loads require.
I'd suggest getting into the manuals and white papers of the inverter manufacturers to determine if they can do this. I believe both SolarEdge and Enphase can do it. I'd assume others can as well.
