Don't know your system specifics but can likely accomplish this by setting Backup reserve to whatever (eg 20%) in Tesla app and then setting up 2 automations in Netzero:I'm also a net exporter and will be following this thread. What I'd be hoping to achieve:
3pm to midnight - Prioritize solar generation to self consumption and send excess to grid. Run off Powerwalls when solar generation is insufficient to power home.
Midnight to sunrise - Continue to run off my Powerwalls until I hit my reserve.
Sunrise to 3pm - Prioritize solar production to self consumption. Send excess solar to Powerwalls until full then send excess solar to grid. If Powerwalls aren't going to be fully recharged by 3pm then engage grid charging to get them fully charged by 3pm.
What I'd really like is a self consumption mode that would never draw from the grid between 4-9pm and only draw from the grid between 3-4pm and 9pm to midnight if necessary to avoid drawing from the grid between 4-9pm.
Looking forward to seeing what other people do.
- 2pm: Time-based Control, Enable grid charge
- 3pm: Self-Powered, Disable grid charge
The last part you could add to the 3pm automation a backup reserve of say, 90%, if you think worst case usage from 4-9pm is 70% of your Powerwalls, then a 4pm automation to change reserve to 20%...
