Can I monitor my energy usage?

Yes! The Tesla app lets you track your energy production, storage, and consumption in real time. You can see how much solar energy your system is generating, how much your Powerwall 2 is storing, and how much electricity your home is using. The app also notifies you of any grid outages, so you’ll know immediately if a blackout occurs. Additionally, it provides insights and tips to optimise your energy usage, helping you get the most out of your solar and battery system while reducing electricity costs.
