Tesla has confirmed that the brand new Mannequin Y Efficiency helps bidirectional charging for each vehicle-to-home (V2H) and vehicle-to-load (V2L) functions.
For now, it solely works with Tesla’s outlet adapter dongle.
We’ve got recognized that Tesla’s onboard charger has had some bidirectional charging capability for some time now.
I even efficiently discharged a 2023 Mannequin Y utilizing my buddy’s new Sigenergy battery system with a bidirectional charger earlier this summer season.
Nevertheless, Tesla doesn’t formally help the capability in any car aside from the Cybertruck… till now.
With the discharge of the brand new Mannequin Y Efficiency within the US yesterday, Tesla has began reaching out to prospects who ordered and confirmed that the car helps bidirectional charging:
- Automobile-to-Load (V2L):
- Powers exterior units (e.g., instruments, tenting gear, home equipment) by way of the cost port utilizing a suitable V2L adapter (e.g., Tesla’s discharger or third-party like Tlyard, ~$200–$400).
- Supplies as much as 11.5 kW of export energy (120V/240V retailers, ~3–5 kW steady) from the 82 kWh battery.
- Enabled by way of OTA software program replace (model 2025.20 or later, anticipated This fall 2025).
- Automobile-to-Residence (V2H):
- Provides energy to a house for backup or grid offset, requiring a Tesla Powerwall 3 or suitable bidirectional inverter and V2H adapter (~$1,000–$2,500 for {hardware}/set up).
Tesla additionally mentioned on X right now:
New Mannequin Y Efficiency presents Automobile to Load (120V 20A AC) with Tesla Outlet Adapter
Primarily based on the communications with prospects and this message on X, it seems that the function solely works with adapters for now, such because the Tesla Powershare outlet adapter:

However extra capability might be enabled via software program updates later this quarter.
Electrek’s Take
Tesla confirmed the function for the Mannequin Y Efficiency, however the car clearly makes use of the identical onboard charger as in different refreshed Mannequin Y.
Moreover, we all know that the onboard chargers in earlier Tesla automobiles for the previous few years are able to bidirectional charging. Tesla is solely not making it obtainable.
Now, it’s confirming it on the brand new Efficiency model to attempt to promote the costlier variant, however I might assume that it’s going to finally be enabled on different automobiles.
There’s no purpose to not, and Tesla would solely obtain function parity with most new EVs hitting the marketplace for years now.
