Tesla OTA update silently disconnects Australian home batteries
Tesla pushed an over-the-air software update that disabled the vehicle-to-home discharge function on Australian Powerwalls and Tesla EVs enrolled in home energy management, cutting households off from using their EV batteries as backup power — without prior notice or an in-app explanation.
- Affected owners bought their EVs specifically for V2H resilience during grid outages
- Tesla cited 'grid compliance review' in one-to-one support responses; no public statement issued
- Australia's energy regulator AEMO has not yet commented; consumer groups have been notified
