Hi ... tried to search to see if this question had been answered, but my Google-fu did not find what I was looking for. Is it known what the efficiency is for exporting solar to grid and reimporting? For example, for every kWh exported to grid, what is the estimated round trip loss? I'm trying to maximize my power generation and would like to charge my Tesla with excess solar once the Powerwalls have fully charged. There has to be some sort of loss during the roundtrip to/from the grid. I also REALLY wish Tesla had better integration to allow you to utilize solar generation in this manner. I have a Wallbox that lets me change the charge rate in the app from 6~40Amp real time - so I can easily adjust charge rate on the fly based on excess generation. I believe the next release of vehicle FW is going to allow this type of setting as well from the Tesla App. Thanks!
