Tesla has expanded its Vehicle-to-Home (V2H) feature to its Model 3 and Model Y, as announced on October 6, 2026. This follows the launch of the Cybertruck in 2023, which originally included Vehicle-to-Load (V2L) capabilities, allowing the vehicle to power external devices, and later introduced experimental Vehicle-to-Grid (V2G) functionality in Texas. The new V2H feature allows the vehicle’s battery to power a home during a blackout or help reduce strain on the power grid during peak times. However, the feature is currently limited in scope and availability. The V2H feature is available to select American owners of the Model 3 and Model Y, enabling the vehicle to act as a backup generator capable of powering a home for more than two days during a blackout. However, Tesla requires owners to purchase a Powerwall 3, its home battery priced at a minimum of €5,500 without installation costs, to unlock the V2H functionality. This requirement does not apply to the Cybertruck, which only needs a "Powershare" gateway to enable similar features. The availability of the V2H feature is limited to specific models. Tesla states that only Model 3 and Model Y vehicles sold in the United States since October 1, 2026, and some earlier models (without further details provided) can access the Powershare function. The availability of this feature in other markets, including Europe, remains unclear. Additionally, the Model 3 and Model Y must be equipped with a specific inverter to activate the function, meaning only newly produced models with the necessary equipment can access the feature. It is currently uncertain whether this functionality will be extended to Tesla’s Berlin plant or other international markets.
