[RE-wrenches] "Keep that there PV off my grid!"

Is this instant excess or excess during a specific billing
period?

Does this violate Federal regulations?

Could you divert or bank the excess in process heat, water
pumping, or some other function?

Greetings Esteemed Wrenches,

 

My company was recently tasked to engineer a PV project in
Alabama. We sat down for a meeting with all of the local
big-shots. They proceeded to let us know that we are not
allowed to feed any excess PV power onto their grid,
production cannot exceed demand. I am hoping that y'all
might be able to steer me towards a contactor assembly or
device that would detect reverse current flow, trigger the
contactor, then open up the inverter AC output circuit. The
service is 3-phase, 208 volt. The maximum current we intend
to introduce is 70 amps, continuous.

 

Appreciate your advice,

 

Karl Jaeger
