Why choose Tesla Powerwall 3 for your battery storage?

Best performance

The Powerwall 3 delivers top-tier performance with a high-efficiency DC-coupled design, ideal to power appliances like hot tub, HVAC, or EV with a single battery.


Most durable

Engineered for resilience, it excels in challenging climates and offers a comprehensive labor warranty, ensuring reliability and a single point of repair.


Easiest to install

Powerwall 3 features straightforward backup installations and DC-coupled battery expansions with a unified app experience.


Best value

Powerwall 3 offers the best value with the lowest installed cost, superior payback economics, and maximum lifetime value, making it a smart financial decision.


Single point of repair

Both inverter and storage issues are addressed in one accessible location, eliminating the need for complex setups or risky trips to the roof to manage micro inverters.


Hurricane proof

Powerwall 3’s resilient design, with all power electronics positioned at the top, ensures it can continue operating even while submerged in water.


10 years of warranty

Powerwall 3 comes with a robust 10-year warranty that covers full replacement costs and labor reimbursement.


Safer battery chemistry

Tesla Powerwall 3 has embraced a significant shift in battery technology by utilizing Lithium Iron Phosphate chemistry, known for its enhanced safety and longevity. This advancement marks a notable departure from the traditional lithium-ion batteries commonly found in electric vehicles. Lithium Iron Phosphate batteries are particularly well-suited for residential use due to their inherently stable chemical structure, which substantially reduces the risk of thermal runaway—a common concern with cobalt-based lithium-ion batteries.

Single power conversion for better efficiency

Tesla Powerwall 3 features a single-step DC to AC conversion process, achieving 89% efficiency, compared to traditional systems with about 86% efficiency due to three power conversions. It handles up to 20kW DC of solar per unit, delivering 11.5kW AC to power homes and simultaneously charging at 5kW DC. Such efficiency allows it to maximize daily solar energy use, support larger systems, and avoid energy wastage, effectively adding 30 extra days of solar production annually. This design represents a significant upgrade from the Powerwall 2, enhancing both energy capture and overall system productivity.


Effortlessly expandable energy storage

Tesla Powerwall 3 is engineered for seamless scalability through its DC Expansion feature, making it simpler and more cost-effective to install systems with multiple units. Each expansion adds 13.5kWh of energy to the Powerwall 3 system without requiring additional expensive components, as these are already managed by the main unit which handles power conversion, site control, and solar coupling. This design significantly reduces the overall cost and complexity of system expansion. The flexibility to add expansions anytime allows homeowners to adapt their energy systems to meet changing needs, ensuring that growing energy demands are met efficiently and economically.
