POWER DURING A GRID OUTAGE
If you face a grid outage, solar and Powerwall automatically become your home’s main energy source. Each Powerwall can provide up to 5 kW of continuous power. You can back up any number of appliances, so long as their combined power usage does not exceed the total power rating of your Powerwalls.
The best way to extend your usage of Powerwall during a utility grid outage is to monitor your use of energy intensive appliances like air conditioners, washer or dryer.
TESLA STORM WATCH
When a storm or severe weather is on the horizon, increasing the likelihood of a utility power outage, Powerwall triggers Storm Watch.
This mode automatically charges Powerwall to maximum capacity so it can provide backup power. The Tesla app sends a notification that Powerwall has activated Storm Watch. The mode remains active until the weather event ends, at which time the system returns to its previously selected mode.
