All-in-One Hybrid System
The smart core of the EcoFlow STREAM Plug & Play Power Plant — combining energy storage and a built-in microinverter in one seamless solution.
How Does It Work to Drive Your Energy Bills to 0?
As the morning sun rises, EcoFlow STREAM Ultra instantly captures solar energy for your home, storing any surplus automatically. At night, this stored power runs your appliances, directly or through the grid. Generating up to 2,218kWh annually, it meets 71.3% of household needs, cutting electricity bills to almost zero¹.
Dual-mode 2800W solar input
EcoFlow STREAM Ultra features a 4-MPPT design, supporting up to 2,000W solar input. It also works with third-party microinverters; connecting to the solar battery adds 800W more. Maximises power generation from every sunlit area.
2300W AC output
Run two appliances independently via dual AC outlets, with 1,200W output per battery and auto-boost up to 2,300W. Pair with another STREAM Ultra or STREAM AC Pro for full 2,300W AC output. The built-in battery ensures off-grid use and backup during outages.
One Step Closer To 0 Bills

FAQ
The system prioritizes solar energy. When solar generation falls short of the power demand, the battery automatically steps in to make up the difference. If there’s still a shortfall, the grid supplies the remaining power.When solar output exceeds consumption, the excess energy is first stored in the battery. Any additional surplus can be exported to the grid, depending on your settings and in compliance with local regulations.
All devices must be connected to the same network and added to the same “Space” within the EcoFlow app.
To access the full functionality of the STREAM Series, a connection to Wi-Fi and the EcoFlow app is required. Bluetooth or LAN-only connections will not support features like remote control or historical data tracking.
Yes, a temperature rise during use is normal and does not affect the product’s lifespan. The unit has passed rigorous testing and includes overheat protection. For best performance, install it out of direct sunlight with at least 3 cm clearance from walls or objects, and away from flammable materials.
The system can be self-installed and maintained. However, in the UK, local regulations require the EcoFlow STREAM DIY Cable to be wired into the distribution board, which must be done by a certified installer or electrician.
If you disable the feed-in protection switch in the EcoFlow app, the excess solar power will be fed into the grid.
For safety and compliance reasons, the STREAM system will automatically detect a grid anomaly and stop feeding current into the grid during a power outage. You can then plug in your appliances directly into the AC outlets to use internal battery or solar power.
Compensation policies may vary by region. You should contact your local grid operator using the contact information provided on your electricity bill to inquire.
As long as the panels meet the input range for the PV port and use the same type of connector, they can be used. Each PV port’s input range is: operating voltage 15-60V, operating current ≤14A.
Due to regulatory limits, it is recommended to connect no more than one microinverter.
Yes, as long as the solar panel meets the conditions of operating voltage (15-60V) and operating current (≤14A). This can optimize solar utilization during low sunlight conditions.
Not necessarily. It might prioritize using one device's power or discharge multiple devices simultaneously. The system employs an intelligent charging and discharging strategy based on the current power levels of the devices, the power consumption of the appliances, the actual connection setup, and your settings in the app. Thus, the discharging performance of specific devices may vary.
The AI TOU feature means that the EcoFlow app will use dynamic electricity price data from the local power company to perform smart charge and discharge strategies based on peak and off-peak pricing, maximizing your electricity bill savings. This feature requires a subscription.*An AI TOU strategy will only be generated when the price difference between peak and off-peak is substantial enough because charging and discharging involve losses. If the economic benefits are less than the battery loss, charging and discharging will not take place.
No. / No. The Portable Power Station can only be charged by the STREAM Series products, not discharge to them. If you need to expand capacity or power, you can increase the number of STREAM Series products in the STREAM system (up to 6 devices per system).
1. EcoFlow STREAM Ultra delivers 2,218kWh of solar energy annually, achieving 71.3% coverage of Germany's average household consumption (3,113kWh/year) through 24/7 solar power supply. Based on the electricity rate of €0.40/kWh, this system provides annual savings of €887. Actual savings may vary depending on usage behavior and regional energy pricing.

3. The maximum capacity is 6 units, expandable up to 11.52kWh with the EcoFlow STREAM Ultra or EcoFlow STREAM AC Pro.
4. Certain AI features in the EcoFlow app require a premium subscription. Please refer to the EcoFlow app for details on subscription plans and feature availability.
5. The calculation is an estimate based on 10 kWh/day electricity consumption in Munich, Germany (representing Central Europe), using STREAM series products (6kWh batteries and 2800W PV). It is simulated by AI, factoring in fluctuations in electricity prices and usage for a closer reflection of real-world conditions. Actual results may vary depending on local conditions.
6. The EcoFlow app integrates weather data from Solcast, running over 100 million data operations per hour to deliver forecasts with up to 94% accuracy and horizons of up to three days. (https://solcast.com/)
7. After installing STREAM Series battery and compatible Smart Meter, users can connect appliances to wall outlets via compatible Smart Plugs, enabling remote on/off control and operation scheduling through the EcoFlow app—thereby minimizing solar energy waste.
