Tesla Powerwall 3 - 13.5kWh Expansion Battery Unit
The Tesla Powerwall 3 – 13.5kWh Expansion Battery Unit is designed to increase the energy storage capacity of your existing Powerwall 3 system. This DC-coupled lithium-ion battery connects directly to the Powerwall 3 and uses the same inverter, making it a simple and efficient upgrade without additional hardware. Built with an IP67 / NEMA 3R weather-rated enclosure, it can be installed indoors or outdoors and operates reliably in temperatures from –20°C to 50°C (–4°F to 122°F). With the ability to add up to three expansion units per Powerwall 3, homeowners can significantly increase backup power and maximize solar energy usage.
