How does the STREAM system work?

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.

EcoFlow STREAM Series Set Specifications

1. STREAM Ultra

EcoFlow STREAM Ultra delivers 2,218 kWh of solar energy annually, achieving 71.3% coverage of Germany’s average household consumption (3,113 kWh/year) through a 24/7 solar power supply. Based on the electricity rate of €0.40/kWh, this system provides annual savings of €1,109. Actual savings may vary depending on usage behaviour and regional energy prices.

2. STREAM Pro

3. STREAM AC Pro

EcoFlow STREAM AC Pro collects 1,041 kWh of solar energy annually. With Germany’s average household consumption of 3,113 kWh/year, this system covers 33.4% of total energy needs through continuous day-night solar supply. The electricity rate of €0.40/kWh translates to an annual savings of €412. Savings may vary based on consumption patterns and energy price fluctuations.

• The maximum capacity is 6 units, expandable up to 11.52 kWh with the EcoFlow STREAM Ultra or EcoFlow STREAM AC Pro.
• The calculation is an estimate based on 10 kWh/day electricity consumption in Munich, Germany (representing Central Europe), using STREAM series products (6 kWh 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.
• After installing the STREAM Series battery and a 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.

FAQ

1. What is required to enable energy balancing between multiple STREAM Series units?
   All devices must be connected to the same network and added to the same “Space” within the EcoFlow app.
2. Does the STREAM Series need to be connected to Wi-Fi and 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.
3. Is it normal for the product to heat up during use?
   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.
4. Can I install the STREAM Series by myself?
   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.
5. Will the excess power generated by the STREAM system be fed into the grid?
   If you disable the feed-in protection switch in the EcoFlow app, the excess solar power will be fed into the grid.
6. How does the system continue to supply power during a blackout?
   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 the internal battery or solar power.
7. Can I receive compensation for excess power fed into the grid by the STREAM system?
   Compensation policies may vary by region. You should contact your local grid operator using the contact information provided on your electricity bill to inquire.
8. Can third-party solar panels be used with the STREAM Series?
   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.
9. How many microinverters can the STREAM Series support? Can third-party microinverters be used?
   Due to regulatory limits, it is recommended to connect no more than one microinverter.
10. Each MPPT of the STREAM Ultra/Pro has a maximum power of 500W. Can I connect solar panels with more than 500W to each port?
    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.
11. If there are multiple devices in the STREAM system, will it prioritize using up one device’s power before starting to use another’s?
    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.
12. What does the AI TOU feature of the STREAM Series refer to?
    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. The 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.
13. Can I connect the STREAM Series to the output port of a Portable Power Station? Can I connect a Portable Power Station to the STREAM Series’ AC outlets to use it as an additional power pack?
    No. / No. The Portable Power Station can only be charged by the STREAM Series products, not discharged 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).
