In times of rising energy prices and growing environmental responsibility, the EcoFlow STREAM Series offers a well thought-out complete solution for anyone who wants to take their power supply into their own hands – uncomplicated, powerful and modular. You can now pre-order the balcony power plant system.
Intelligent energy supply through AI – the new standard
Conventional balcony power stations have their limits – for example in terms of limited feed-in power or the inconvenience of changing batteries. The STREAM series addresses these limitations with a sophisticated concept: an AI-supported balcony power station network. This networks and controls several batteries in the entire household fully automatically. This means that even appliances with high energy requirements can be supplied with solar power at all times – regardless of the time of day or battery position.
At the heart of this innovation is the intelligent control system, which coordinates and prioritizes all energy sources in the household. The AI decides independently when energy is stored, used or fed into the grid – depending on consumption patterns, the position of the sun and the electricity tariff. The big advantage: users don’t have to worry about anything, but benefit from maximum efficiency and minimum electricity costs.
According to the manufacturer, the EcoFlow app plays a central role in this. It offers functions such as AI-TOU (Time-of-Use), which automatically charges batteries at off-peak times and discharges them at peak times, as well as an AI power forecast that predicts generation and consumption with up to 94% accuracy. The Adaptive Energy Architect continuously analyses consumption patterns and optimizes system settings in the background – a real highlight for smart home enthusiasts.
Flexible system variants for beginners to power users
The STREAM series comprises four central components: STREAM Ultra X, STREAM Ultra, STREAM Pro and STREAM AC Pro – each designed for different user groups. The micro inverter with up to 1,200 W PV input is recommended for beginners. Those who already have a solar system, on the other hand, can expand the storage system modularly with the STREAM AC Pro, which is scalable from 1.92 kWh to up to 21 kWh.
The high-end STREAM Ultra and STREAM Pro models score points with all-in-one functionality, i.e. integrated storage and inverter in one device. Particularly impressive: the STREAM Ultra achieves a combined PV input of up to 2,800 W, which is more than sufficient even for larger households or intensive usage scenarios.
Another highlight is the 2,300 W dual-mode bypass AC output: this allows almost all household appliances – from coffee machines to air conditioners – to be supplied directly with solar power. The parallel feed into the grid and supply of appliances via direct connection ensures maximum flexibility.
Plug & play with style and safety
Despite its advanced technology, the STREAM series remains extremely user-friendly. Installation is carried out without drilling or complex cabling: simply connect and solar power production begins. The design is compact, around 40 % smaller than conventional systems and therefore also fits on small balconies or in urban apartments.
EcoFlow has also thought about safety: IP65 weatherproofing, overcurrent protection and whisper-quiet operation at just 30 dB guarantee reliable use – indoors and outdoors, in sunshine and rain.

The EcoFlow STREAM Series is more than just a balcony power station – it is a scalable, intelligent and user-friendly energy system that combines modern technology with real utility value. Ideal for anyone who wants to reduce their energy costs and improve their carbon footprint while maintaining control over their power supply.
You can now pre-order the models from the EcoFlow STREAM series in the EcoFlow online store and on Amazon. You can save big during the Early Bird promotion period until May 31, 2025.
The STREAM series from EcoFlow officially launches on May 15 at 9 a.m. (CET) and sets a new industry standard in the balcony power plant sector – with powerful, AI-supported energy management via the EcoFlow app. STREAM users get access to a free standard plan or can upgrade to the premium plan for even more control, automation and optimization options.
Free plan with best-in-class features
The standard plan, which is available to all STREAM users free of charge, already outperforms many competitive offerings:
- AI Mode: combines solar forecasts, time-of-use (TOU) electricity rates and real-world consumption patterns for smart scheduling solutions.
- AI assistant: Supports users in goal setting and energy planning through smart question-answer interactions.
- Prioritization of energy consumption: Intelligent planning of grid charging/discharging and appliance use.
- Automatic emergency power supply, self-consumption mode, battery SOC balancing technology and more.
Premium plan: For power users
The Premium plan (€9.99/month or €99/year) extends the range of functions by:
- Enhanced AI mode: real-time load forecast and precise solar forecast (accuracy: 94%); supports dynamic price data from over 600 energy providers in Europe; increased AI computing power.
- AI Energy Insights (to be released in August): Provides in-depth diagnostics, efficiency analysis and individual optimization recommendations.
- Pro-level prioritization of energy consumption (coming in August): Utilizes preset or custom prioritization and automation combined with solar redundancy and dynamic pricing to intelligently manage appliances for maximum solar energy usage and overall efficiency.
From May 15 to August 31, all STREAM customers will receive a 3-month free trial of the premium plan.
If users decide to upgrade to the annual plan by December 31, 2025, they will benefit from a €30 discount and pay only €69 per year.
