Tesla Powerwall Monitoring

Tesla Powerwall 3 Monitoring

The Tesla Powerwall 3 comes with built-in energy monitoring through the Tesla app, giving you real-time insights into your solar production, battery storage, and home energy usage. You can track how much energy your home is using, how much solar you’re generating, and how much is being stored or exported to the grid — all from your phone.

Whether you’re at home or away, the Tesla app allows you to manage your energy system with ease. You can view backup status during a power outage, set usage priorities, and monitor savings over time. It’s simple, smart, and gives you full control over your home’s energy — anytime, anywhere.
Stay Powered During Storms
Stay connected during blackouts. When severe weather is on the way, Storm Watch automatically charges your Powerwall to full capacity. If the power goes out, Powerwall instantly takes over — keeping your lights, appliances, and even your solar system running.
