Note: This guide relates to the use of Tesla Energy products for charging your EV from solar energy. See also our guide on Tesla EV compatibility.
Charge from gross solar production
EV charging can be matched to gross solar production for all Internet connected Tesla Solar Inverters, Gateways and Powerwalls.
Charge from excess solar production
EV charging can be matched to excess solar production where home energy consumption is monitored.
- Tesla Powerwall: Standard
- Tesla Energy Gateway: Optional
- Tesla Solar Inverter: Optional
If you would like to match your EV charging to excess solar production (rather than gross solar production) you will need to have monitoring of home energy consumption. Your options include:
Supplied by Tesla these meters integrate directly with the Tesla Solar inverter or gateway and provide visibility of all of your home energy consumption in the Tesla app. Contact Tesla for supply and installation.
Stand alone solar and grid monitoring
A separate solar and grid monitor can be installed to provide Charge HQ with a compatible solar data source.
Australian users: Wattwatchers, Solar Analytics
AC Coupled batteries
Users with a Tesla solar system that also have a supported AC coupled battery can rely on the battery integration which will include grid monitoring. A separate grid meter for the solar inverter is not required in such cases.
