Tesla Energy is a pioneer in residential energy storage, best known for its flagship Powerwall home battery. Designed to deliver energy independence, whole-home backup power, and lower electricity bills, Tesla Powerwall systems store energy from solar panels or the grid for use anytime — day or night, during outages, or when utility rates are highest.

At the heart of Tesla’s residential battery lineup is the Powerwall 3, a fully integrated solar and storage solution. Each unit provides 13.5 kWh of usable energy capacity and delivers up to 11.5 kW of continuous AC power — enough to support most homes, including high-demand appliances like central air conditioning, well pumps, and electric ranges. With an integrated solar inverter supporting up to 20 kW DC of solar input, Powerwall 3 offers higher efficiency and simpler installations compared to previous generations.

Key Advantages of Tesla Powerwall

• Whole-Home Backup — Automatically detects outages and seamlessly powers your entire home without interruption.
• Scalability — Easily expand by adding Powerwall 3 units (up to 4) and Powerwall 3 Expansion modules (up to 3 per base unit) for total capacities reaching 94.5 kWh and continuous power up to 44 kW.
• Smart Energy Management — The intuitive Tesla App lets you monitor usage, customize modes (Storm Watch, Self-Powered, Time-Based Control), and optimize for maximum savings or resilience.
• Durability & Safety — Outdoor-rated (IP67), operates in extreme temperatures (-20°C to 50°C), and uses advanced lithium iron phosphate (LFP) chemistry for long life and enhanced safety.
• High Efficiency — Up to 97.5% solar-to-home/grid efficiency and strong performance in hot or cold climates.

Tesla Powerwall works with new or existing solar systems and can also be installed grid-only for backup and bill reduction. It supports seamless integration with Tesla’s ecosystem and third-party solar inverters (via Powerwall 2 compatibility where needed).

Backed by a 10-year warranty and proven in real-world outages worldwide, Tesla’s residential battery solutions continue to set the standard for reliable, intelligent home energy storage.

Whether you want to maximize solar self-consumption, protect against blackouts, or reduce peak-time charges, Tesla Powerwall delivers a smarter, more resilient way to power your home.
