More and more people want not only to generate their own solar energy, but also to use it intelligently at the moments that matter. The EcoFlow STREAM Ultra X + STREAM AC Pro is a bundle consisting of two Stream units that together form one powerful and flexible Stream setup. The Ultra X is installed outdoors and processes the energy generated by the connected solar panels, while the AC Pro ensures stable and efficient distribution to appliances and the home electrical system indoors.
Within this setup, the two models complement each other logically. In this bundle, the Stream Ultra X is the unit to which the solar panels are connected. With four MPPT inputs, it supports a total solar input of up to 2000 W. This allows you to build a compact system in which surplus generation does not immediately flow back to the grid, but remains available for later use. The Stream AC Pro strengthens the AC side of the system. By operating two units that work together as a single set, you create a more stable foundation for powering appliances, handling fluctuating loads, and distributing stored energy more efficiently.
In terms of output, each unit delivers 1200 W. As a combined set, this results in up to 2300 W, sufficient to power multiple devices simultaneously via the AC outlets. Feed-in via the wall socket is possible up to 800 W per unit, with a maximum feed-in power of 800 W per phase. When solar generation is temporarily lower, the system can, if configured, also recharge from the grid at favorable times, for example when using a dynamic energy tariff.
Control is handled via EcoFlow OASIS with the AI Energy Assistant. The app analyzes consumption, generation, and tariffs in real time and automatically switches between direct use, storage, feed-in, and grid charging. This allows you to get more out of your solar panels and build a Stream setup that can later be easily expanded with additional Stream units, up to a maximum storage capacity of 11.52 kWh.
