Today for about 4 hours after charging up my PW's, I am feeding approximately 5kWh according the the Tesla App. How does that power returned back into my PG&E account. Is my smart meter actually running in reverse? Does the smart meter track the usage based on forward and backward? So at the end of the year the Smart Meter will either have forward balance or a reverse balance. I am trying to understand exactly how I get full utilization of returning power to the grid. Can someone help me understand how this works.
