From ESS News

Tesla has added a new product to its residential battery energy storage offering, making it possible for Powerwall 3 owners to expand their systems more affordably and effectively.

Just like Powerwall 3, the DC expansion unit has an energy capacity of 13.5 kWh. However, it does not integrate some expensive components, such as an inverter, which makes it $1,000 cheaper than a regular Powerwall 3.

Powerwall 3 owners can add up to three expansion units to increase their system’s capacity. In such a setup, the original Powerwall 3 is responsible for power conversion, site control, and solar coupling.
