Product description

2000 W EcoFlow STREAM Ultra X Balcony Power Plant – Complete Set with Storage, Mounting Brackets & Bifacial Solar Modules

With the 2000 W EcoFlow STREAM Ultra X balcony power plant, you get an efficient complete solution for decentralized energy supply directly at home. The set combines four State-of-the-art DAH Solar Frame Black 500 W bifacial solar modules with the powerful EcoFlow STREAM Ultra X including microinverter, 3.84 kWh storage and four WATTSTUNDE balcony brackets – ideal for quick installation on mesh balconies.

Maximum yields in a limited space – 4x DAH Solar Frame Black 500 W

DAH Solar's bifacial double-glass modules enable up to 25% higher energy yields compared to conventional solar modules thanks to their ability to utilize light from both sides. The integrated N-type TOPCon cell technology ensures exceptionally high efficiency, low degradation, and reliable performance – even in low light conditions. A 30-year performance guarantee provides additional investment security.

EcoFlow STREAM Ultra X – Maximum flexibility with 4 MPPT inputs

The EcoFlow STREAM Ultra X is a particularly powerful, AC-coupled energy storage system with a capacity of 3.84 kWh, four MPPT inputs (2000 W total), and modular expandability up to seven units. It can be integrated into existing balcony power systems via plug & play, supplies even high-power appliances up to 2300 W, and optimizes self-consumption thanks to the EcoFlow OASIS app and smart meter connectivity. Ideal for maximum independence, efficiency, and flexible energy supply.

Set contents:

  • 1 × EcoFlow STREAM Ultra X with integrated inverter and 3.84 kWh storage
  • 4 × DAH Solar Frame Black 500 W bifacial solar modules (double glass, N-Type TOPCon)
  • 4 × WATTSTUNDE balcony bracket BKW-HS (black) for mesh balconies
  • 4 x 3 m connection cables (MC4) for solar modules
  • 1 x 1.5 m Schuko cable for mains connection

Easy installation on the railing balcony – ready for use in no time.

Connecting the solar panels to the EcoFlow STREAM Ultra X is particularly straightforward thanks to the four integrated MPPT inputs. Each panel can be connected individually and independently – for maximum flexibility in terms of orientation and placement. The WATTSTUNDE balcony brackets BKW-HS included in the set ensure secure and stable mounting of the panels to the balcony railing. Four 4-meter connection cables and a 1.5-meter Schuko cable for mains connection are also included. This means your balcony power plant is ready to use in just a few minutes – no technical expertise required.

Intelligent energy distribution – greater self-sufficiency, lower electricity costs

The STREAM Ultra X detects your energy needs in real time, learns from them, and distributes power precisely where you need it – whether in the kitchen, home office, or workshop. With the EcoFlow app, you maintain full control over your energy flows and can conveniently optimize your consumption via smartphone.
