Your savings with STREAM

Herein lies the biggest advantage: With an EcoFlow STREAM balcony power plant, you not only lower your electricity bill – you use self-generated electricity precisely when you are at home . The stored solar power supplies you in the evenings and mornings, instead of going unused at midday. Even an average household with an annual consumption of 3,500 kWh (approx. €1,395 electricity costs/year) can save up to €350 per year .

👉 Your investment will have paid for itself in just two years – and you'll benefit permanently after that. The EcoFlow app helps you get even more out of it: schedules, automations, and integration into your smart home (e.g., Shelly, Tibber, Tapo) ensure that devices run exactly when battery power and sunlight are available.

Example calculation (simplified assumptions)

• Electricity price: €0.40/kWh (≈ €1,395 / 3,500 kWh)
• Daily profile: You are often out and about during the day, using electricity mainly in the mornings/evenings .
• PV generation: On average , 3.0 kWh of solar power is available per day.

Without storage

• Used directly during the day: 1.0 kWh
• Unused: 2.0 kWh
• Savings per day: 1.0 kWh × €0.40 = €0.40
• Approximately €146 per year

With STREAM Max (1.92 kWh) + app control

• Used directly during the day: 1.0 kWh
• Stored in the battery and used in the evening: 1.5 kWh
• Remaining (weather/losses): 0.5 kWh
• Savings per day: (1.0 + 1.5) kWh × €0.40 = €1.00
• Approximately €365 per year

What the app specifically offers

• Schedules: Dishwasher/dryer start automatically when the battery reaches a certain level.
• Load shifting: Operate the hot water boiler or heating pump in the evening using stored energy.
• Optimization: Smooth out peak consumption and maximize self-consumption with smart home partners (e.g. Shelly, Tibber, Tapo).

This will noticeably increase your self-consumption rate and your independence from the grid. Every kilowatt-hour you consume yourself reduces your running costs – day after day.

• Tibber: Take advantage of dynamic electricity tariffs and optimize your grid consumption. Your STREAM system can then adapt to off-peak tariff times and increase your self-consumption.
• Tapo: With Tapo's smart sockets and lamps, you can conveniently control devices via app and ensure that solar power is used efficiently.

Your everyday benefits

• Automation: Appliances such as washing machines, dryers or dishwashers start precisely when stored solar power is available.
• Flexibility: Adapt schedules and routines to fit your daily schedule.
• Convenience: Everything can be centrally controlled via the EcoFlow app and combined with other smart home components.

This way, your STREAM becomes not just a power source, but the heart of a smart and efficient home.
