Product description

2000 W EcoFlow STREAM Ultra X Balcony Power Plant – Set with 3.84 kWh Storage & Roof Mounts

The 2000 W EcoFlow STREAM Ultra X balcony power plant is your premium solution for maximum independence and extended storage times. With four 500 W DAH bifacial solar panels, a powerful 3.84 kWh battery, and a comprehensive WATTSTUNDE roof mounting kit for tiled roofs, you receive a complete package that perfectly combines efficiency, performance, and safety.

Maximum energy yield with bifacial modules

DAH's four 500W double-glass modules utilize sunlight from both sides, generating up to 25% more energy than conventional solar panels. Thanks to state-of-the-art N-Type TOPCon cell technology, you benefit from high efficiency, low degradation, and a long lifespan – backed by a 30-year performance guarantee.

EcoFlow STREAM Ultra X – double the storage capacity

The STREAM Ultra X offers double the storage capacity of the STREAM Ultra with its 3.84 kWh LiFePO4 battery. Four MPPT inputs allow you to operate each module separately – perfect for different roof orientations or partial shading. This ensures you get the most out of your solar setup, even with complex roof conditions.

Complete set with WATTSTUNDE roof mount

For secure installation, the set includes a complete WATTSTUNDE mounting system for tiled roofs. With sturdy roof hooks, rails, end and mid clamps, you can mount your solar panels securely, weatherproof, and durably directly onto your roof.

Easy installation & smart control

The pre-assembled cables and Schuko plug make setup particularly easy. The EcoFlow app gives you full control over generation, storage status, and consumption at all times – directly from your smartphone.
