1.The estimated electricity cost savings are calculated using the following formula: Annual Savings = Annual Solar Generation × electricity price × Self-Consumption Rate Annual Solar Generation: Based on the configured solar input capacity (W), assuming installation in a typical Central European city (e.g. Munich, Germany), facing due south (180°) at a 40° tilt. Three common configurations include: - 2 × 520W panels → approx. 1,000W input - 4 × 520W panels → approx. 2,000W input - 4 × 520W + 2 × 450W panels → approx. 2,800W input Generation estimates are based on an average of 4.5 sunlight hours per day. Source: https://pvwatts.nrel.gov/pvwatts.php Electricity Price: Based on national residential electricity averages, which vary by country and provider. For calculation purposes, €0.40/kWh is commonly referenced as a representative average for Germany. Self-Consumption Rate: Estimated using HTW Berlin’s Independence Calculator, assuming an average annual household electricity consumption of 4,000 kWh. Source: https://volker-quaschning.de/software/unabhaengig/index_e.php Actual savings may vary depending on installation conditions, household consumption habits, regional weather, and electricity tariff changes. The estimated environmental contribution is calculated using the following formula: Annual Environmental Contribution (kg CO₂e avoided) = Annual Solar Generation × 997 / 1000 This formula assumes that for every 1,000 kWh of solar energy generated, approximately 997 kg of CO₂ emissions are avoided. Actual environmental impact may vary depending on the local electricity mix and carbon intensity in your region. 2. The maximum capacity is 6 units, expandable up to 11.52kWh with the EcoFlow STREAM Ultra or EcoFlow STREAM AC Pro. 3. 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. 4. 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. 5. 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/) 6. 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. 7. Actual EcoFlow app functionality may vary; the screens shown are for illustrative purposes only.
