I have solar and Powerwalls and I've been TBC for a while now. I'm on PG&E EV2A and have set the times and buy rates to match EV2A. I set the sell rate rate at $0.03 less to account for NBCs.
When recharging the Powerwalls in the mornings it works the way I want. It prioritizes my solar consumption to the house over running it from the grid and only runs from the grid when there is no solar or it thinks the Powerwalls aren't going to get recharged before 3 pm. However during partial peak and peak it exports all solar to the grid and my house runs off the Powerwalls. During partial peak and peak hours I want it to self consume the solar, send the excess to the grid, and only draw from the Powerwalls when I'm not producing enough solar.
Someone suggested setting the sell price to accommodate round trip losses so I set off partial peak and peak sell prices to the buy price minus 10% minus $0.03. Nothing changed.
Someone said that setting the sell price to 15% lower than the buy prices would make it prioritize self consumption of solar during peak hours so I tried that. It ran just like when I had the sell prices set to $0.03 lower or included round trip losses.
So then I tried setting the sell price to $0.10 across the board for off peak, partial peak, and peak to see what happened. That caused me to run off the Powerwalls during off peak and run off the grid during peak.
So then I tried setting the sell prices to 20% lower than the buy prices. That worked! - for one day. Then it reverted to exporting all solar to the grid during partial peak and peak hours.
People have claimed that they have been able to prioritize self consumption of solar during partial peak and peak hours by manipulating the rates. What rates do I enter to achieve this?
