Product description

1720W EcoFlow STREAM Ultra Balcony Power Plant – with STREAM AC 3.84 kWh total capacity

With the 1720 W EcoFlow STREAM Ultra balcony power plant, you get a powerful complete solution for decentralized power generation. The set combines four high-quality DAH Solar 430 W bifacial solar modules with the advanced EcoFlow STREAM Ultra 1.92 kWh energy storage system and the EcoFlow STREAM AC expansion battery. A BKW smart meter for precise consumption analysis and the appropriate parallel connection cable are also included.

Maximum yields thanks to bifacial technology – 4× DAH Solar 430 W

The bifacial double-glass modules utilize light from both sides, enabling up to 25% higher yields . The N-type TOPCon cells stand for high efficiency, low degradation, and reliable performance – even in lower light conditions. The 30-year performance guarantee ensures long-term peace of mind.

EcoFlow STREAM Ultra – Intelligent control & flexible MPPTs

The STREAM Ultra offers you a weatherproof IP65 housing, integrated inverter and 1.92 kWh LiFePO4 storage. Four independent MPPT inputs allow for optimal alignment of each module group – perfect for variable installation areas.

EcoFlow STREAM AC – Expandable storage for growing needs

The STREAM AC is a pure expansion battery without its own AC output and adds another 1.92 kWh to your STREAM system with additional storage.

3.84 kWh total capacity – simply connected

The included STREAM parallel connection cable (55 cm) allows you to seamlessly combine STREAM Ultra and STREAM AC into an integrated 3.84 kWh system . This way, your balcony power plant can be flexibly adapted to your needs.

EcoFlow Smart Meter BKW – Full control over your energy consumption

The 3-phase EcoFlow Smart Meter delivers minute-by-minute consumption data directly to the app. It detects peak consumption, helps with optimization, and shifts loads to cheaper tariff times – the ideal basis for an energy-efficient home.

Set contents:

  • 1 × EcoFlow STREAM Ultra with 1.92 kWh LiFePO4 storage & integrated inverter
  • 1 × EcoFlow STREAM AC extension battery
  • 4 × DAH Solar 430 W bifacial solar modules (N-Type TOPCon, double glass)
  • 1 × EcoFlow Smart Meter BKW
  • 1 × STREAM parallel connection cable (55 cm)

Quick installation – completely plug-and-play

The four MPPT inputs allow for direct connection of the modules. Pre-assembled cables and Schuko plugs make installation easy, even without prior knowledge. Your system will be ready to use in no time.

EcoFlow App – Monitor energy flows live

With the EcoFlow app, you control your entire system. You can see in real time how much electricity is generated, stored, or consumed – and easily optimize your self-consumption via smartphone.

Your advantages at a glance:

  • Total power: 1720 W (4 × 430 W bifacial DAH) + 3.84 kWh storage
  • Up to 25% higher yield thanks to bifacial module technology
  • Intelligent control via EcoFlow App & Smart Meter
  • 4 MPPT inputs for optimal module alignment
  • IP65 – weatherproof & durable
  • Up to 6000 charging cycles at 70% capacity
  • 10-year warranty on the STREAM system, 30 years on solar modules

Whether as an entry into solar energy or as an expansion for more independence – the EcoFlow STREAM Ultra balcony power plant with 3.84 kWh storage offers you maximum flexibility, smart control and reliable efficiency.
