PV SOLAR PANEL ARAY, 6 pnls
My utility does not credit or compensate for excess power. Trying to detect when power is going back into grid, "excess pwr". Smart meter has a LCD display of " ERR 07" when excess per flowing to utility. When detecting power direction l will contactor switch to water heating or home heating. This would economically encourge green energy production. Can you help?

For a whole lot of reasons I wish there was an energy efficient way to do this without having a grid-connect system, but that's not your question.

Can you read the smart meter in real time? If you can get a data stream from it, you can use something to switch appliances on and off in order to "waste" the minimum amount of power -- or in your case store it in the form of heated water.

My first stop would be determining if I can read the meter data remotely and in real time.
