Tesla Adds Powershare Home Backup to Model 3 and Model Y in US
Tesla has extended its Powershare Home Backup function to the Model 3 and Model Y, allowing the vehicles' traction batteries to supply electricity during a grid outage, according to electrive.
Tesla estimates that the Premium and Performance versions of the Model 3 and Model Y can provide more than two days of household backup power for a home consuming 30 kWh per day, electrive reported.
The system can supply up to 11.5 kW of continuous power. Powershare Home Backup currently requires a Tesla Powerwall 3 and a compatible Tesla Wall Connector.
Tesla guarantees compatibility for Model 3 and Model Y vehicles ordered in the US and Puerto Rico from 1 October 2026 onward, according to electrive. Some earlier vehicles will also be compatible depending on their hardware, though the brand does not assure this.
