For optimal functionality, including firmware updates and remote monitoring, a stable internet connection is recommended.If the Powerwall is disconnected from the internet, it will still function but may not be able to adjust settings or receive updates until reconnected. Additionally, it can operate using a landline telephone connection if needed.In summary, while the Powerwall can function offline during power outages, maintaining an internet connection is beneficial for full operational capabilities and system management.
