Product description
1425 W EcoFlow STREAM Ultra Balcony Power Plant – Set with Battery, 3 × 475 W Bifacial Solar Modules & Flat Roof Mounts
With this 1425 W EcoFlow STREAM Ultra balcony power plant, you get a powerful combination of 3 × 475 W bifacial solar modules, the EcoFlow STREAM Ultra with integrated microinverter and 1.92 kWh LiFePO4 battery, as well as 3 × WATTSTUNDE® flat roof mounts. This makes the set particularly suitable for stable installation on garage, terrace, or garden shed roofs – and for anyone looking to noticeably increase their self-consumption and energy independence.
Maximum Yield in Limited Space – 3 × DAH Solar Frame Black 475 W
The bifacial dual-glass modules from DAH Solar utilize light on both sides, achieving up to 25% more yield compared to traditional modules. Thanks to N-Type TOPCon technology, you benefit from high efficiency, low degradation, and reliable performance – even in weaker sunlight. The 30-year performance warranty provides additional peace of mind for your planning.
EcoFlow STREAM Ultra – Maximum Flexibility with 4 MPPT Inputs
The EcoFlow STREAM Ultra is a robust energy management system with an IP65 rating and an integrated inverter. The 1.92 kWh LiFePO4-based battery helps you not only generate solar power but also store and use it effectively. With 4 independent MPPT inputs, each module or module group can be operated optimally – ideal for different orientations or partial shading.
Set Contents:
- 1 × EcoFlow STREAM Ultra with integrated inverter and 1.92 kWh battery
- 3 × DAH Solar Frame Black 475 W bifacial solar modules (dual-glass, N-Type TOPCon)

Simple Installation on a Flat Roof – Quickly Ready for Use
Connecting to the STREAM Ultra is comfortably flexible thanks to the four MPPT inputs: you can connect each module individually and choose the orientation and tilt angle to suit your space. The WATTSTUNDE® HST120 flat roof mounts ensure a secure, stable attachment on a wide variety of flat roofs. With the 4 × 3 m MC4 cables and the 1.5 m Schuko cable, the system is quickly operational – without any complicated installation.
Intelligent Energy Distribution – More Independence, Lower Electricity Costs
The STREAM Ultra tracks your demand in real-time, learns typical consumption patterns, and directs energy precisely where it is needed – for example, in the kitchen, home office, or workshop. This allows you to increase self-consumption and reduce grid reliance in your daily life.
