[RE-wrenches] how to prevent selling to grid with grid tie inverter

[Will White]

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.

Thanks,
Will
