Intelligent energy management with AI
The integrated AI system recognizes consumption patterns, analyzes tariff data, and automatically redirects energy as needed. For even distribution, energy from other units is switched on when one unit reaches its capacity limit. This ensures a continuous supply and optimal utilization of the stored electricity.
Dynamic electricity tariff usage (TOU model)
The Time-of-Use (TOU) model analyzes electricity prices from sources such as Nord Pool, Epex Spot, or Tibber in real time. The system automatically charges when prices are low and feeds in when prices are high—for maximum savings through intelligent tariff usage.
The STREAM Ultra Bundle includes:
- 1x EcoFlow STREAM Ultra 1.92kWh all-in-one storage system 4 MPPT
- Depending on selection: 1x - 5x EcoFlow STREAM AC Pro 1.92kWh LiFePO4 2300W storage
- Depending on selection: 1x - 3x EcoFlow STREAM Parallel Connection Cable 0.55m
EcoFlow STREAM Ultra
The EcoFlow STREAM Ultra (MPN: EFSTREAMULTRA800W-EU) combines solar power generation, storage, and an integrated micro inverter in one compact system—ideal for almost complete self-sufficiency. With up to 2,218 kWh of yield per year, it covers around 71% of a household's electricity needs. Thanks to four MPPT inputs and up to 2,000W of PV power, it makes optimal use of every minute of sunshine. In typical households, savings of up to €1,109 per year are possible – without feeding into the grid, but through clever self-consumption optimization.
