That's a valid concern. They need X amount of road tested miles before they can release a beta to customers. With not many Cybertrucks driving around it'll take a long time to achieve that.

Do you need a Powerwall to take full odvantage of the Power Share? What if you have to go somewhere in the CT, will your house lose power if you don't have a Powerwall?
Is the battery in the CT a 12 volt or a 48 volt? If it's a 48 volt then it's probably a lithium battery in which case it could have shut itself down due to an internal failure or being discharged too much.
