Connecting a Tesla Powerwall

You sign in with Tesla, not with us. Once you approve, the forecast reads what your Powerwall is doing every five minutes, and the Action plan can set battery timers on it.

Connect in three steps, and we never see your password

On your Account page, open the inverter card, pick Tesla Powerwall, give it a name and press Connect.
Tesla’s own sign-in page opens. Sign in there and approve access to your energy site. Your password goes to Tesla, not to solarprod.
You land back on your Account page with the Powerwall connected. If your Tesla account has more than one site, pick the one you want.

What we read: solar, battery, grid and load

Solar production, grid import and export, and household load, every five minutes.
Battery charge level, every fifteen minutes. That is as often as Tesla gives it.
Your day-by-day history, so the forecast can check itself and learn your shading and usage.

What we can set: battery timers, and your backup reserve

Press Implement this plan under the Action plan and we turn it into import and export timers on the Powerwall. The battery follows them at full power in both directions.

Timers are rebuilt every morning from the new forecast, so they track the weather and your plan.
Your backup reserve is set to the floor in your layout, so a blackout still finds charge in the battery.
Turn it off at any time from the same panel, and the Powerwall goes back to running itself.

One thing Tesla keeps to itself: stopping solar export

We can tell the Powerwall not to export, and Tesla will accept the setting. On most Australian sites it then does nothing, because Tesla only switches owner export control on when their support team enables it for the site. So the negative-price shield can stop the battery exporting, but not your panels.

If negative prices matter to you, ask Tesla support to enable export control on your site. Once they do, the shield works as intended.
Battery timers are not affected. They work whether or not export control is enabled.

If the connection stops, reconnect and nothing is lost

Tesla sign-ins expire now and then. The card shows the connection as needing attention; press Connect and approve again.
Reconnecting picks up the same site, so your layout, timers and history carry on.
To disconnect for good, remove the connection on your Account page and revoke solarprod from your Tesla account settings.
