Tesla Powerwall Self-Powered Mode

Tesla Powerwall Monitoring

Self Powered mode is the most popular Powerwall operating mode, and allows for self consumption, or operating exclusively from your own solar energy and stored battery power all day to the maximum capabilities of your system. Self-powered mode stores any solar energy that is not used during daytime to control your home in the evening. Whenever excess solar power is generated, Powerwall will charge.

Consume Power from Solar All Day and Night

Self Powered Mode

Self Powered mode works to keep your home from pulling energy from the grid as much as possible. The Powerwall will kick in and supply power anytime you don’t have enough solar energy to cover your home consumption. In properly sized systems where Self Powered mode is selected, homeowners will see solar powering their home usage during the day with excess energy routed to charge the Powerwall, and any excess beyond that will backfeed into the grid for net metering credits. In the evening when there’s no solar, or any time the home draws more energy than solar can provide, the Powerwall will kick in and supply power to the home loads with previously stored solar energy. It’s possible to size a system so the home practically never needs to pull energy from the grid.

How Self Powered Mode Works

Self Powered mode will algorithmically learn your home’s usage patterns and optimize to best offset them. Any time the Powerwall reads home consumption in the absence of solar energy or when that consumption exceeds solar energy production, it will discharge power to supply it. A reserve can be set anywhere from zero to 100 percent, once the Powerwall hits a state of charge that matches the reserve, it will pause Self Powered function and reserve its remaining energy in case of a power outage.

Does it only Power my Backed Up Loads?

No. It doesn’t matter what loads are in your backup load center as long as your system is functioning with a grid connection. The Powerwall can read all home consumption, so any time any load consumes energy, the Powerwall is able to discharge to offset it.

Will it Still Work in an Outage?

Yes. Any time an outage occurs, the Powerwall will automatically respond and switch to backup mode. The reserve setting also allows to always save an amount of energy of your choosing in case of an outrage. Note it’s okay to keep your reserve setting low under normal conditions–since solar will cover your usage during the day, the reserve can be set to just high enough power so your home could withstand an outage that occurs in the evening to the time the sun comes up and solar starts generating the following day.

How to Set Your App to Self Powered Mode:

Step 1: Select the “Customize” Menu from your Tesla App Homescreen

Step 2: Select the “Backup Only” Operating Mode

In Self Powered Mode, the system will optimize solar energy to the home, Powerwall and grid backfeed.
