Wait a minute! You are not using a net metering arraingement. You have one meter for the service feeding the house and shop, and a second meter for the inverter output. You are buying High (Utility) and selling Low (Solar). Correct?

You want to use the "cheaper" solar power when it less than the utility power and buy the utility power when there isn't enough solar.
