Regarding "Casey, bschwartz did it through an inverter."
Yes, I am grid tied.
Yes, I do sometimes run the meter backwards with my diesel engine.
NO, it is not approved that way by the power company.
They are OK with my solar panels turning my meter backwards, but if they ever thought that I was using my engine to supliment it, they might just yank my permit.
In this small town, I don't suspect for a minute that anyone would ever know (or really care that much) the source of my power generation.
Original point of Casey's still stands. My system is NOT grid tied approved with the diesel.
