    Powerwall 3 Quick Start

    In the rapidly advancing world of home energy solutions, the Powerwall 3 by Tesla represents a significant leap forward. This latest iteration not only retains the 13.5 kWh capacity of its predecessor, the Powerwall 2, but dramatically enhances output capabilities to 11.5 kW of continuous power.

    Substantial Improvements

    This marks a substantial improvement over the 5 kW offered by the Powerwall 2, with a peak output soaring to 36 kW for one second to accommodate very large loads, then a continuous 11.5 kW for all loads running in a house.

    The implications for homeowners are profound, enabling whole home backup with a singular unit, thereby eliminating the need for a critical loads panel.

    Coupling & Stacking

    The Powerwall 3’s versatility is further underscored by its AC and DC coupling capabilities, making it a more efficient choice for new solar installations or retrofitting existing systems. This feature, coupled with its ability to stack up to three additional 13.5 kWh DC battery units, distinguishes it from the Powerwall 2, allowing for up to 216 kWh of capacity!
