Product description

2000 W EcoFlow STREAM Ultra X balcony power station – set with 3.84 kWh storage & roof mounts

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

Maximum energy yield with bifacial modules

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

EcoFlow STREAM Ultra X – double storage capacity

With its 3.84 kWh LiFePO? storage capacity, the STREAM Ultra X offers you twice the storage capacity of the STREAM Ultra. Four MPPT inputs ensure you can operate each module separately – perfect for different roof orientations or partial shading. This allows you to make the most of your solar setup, even under 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, and end and center clamps, you can mount your solar modules securely, weatherproof, and durably directly on your roof.

Easy installation & smart control

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

  • 1 × EcoFlow STREAM Ultra X with 3.84 kWh storage, integrated inverter & 4 MPPT inputs
