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 added when one unit reaches its capacity limit. This ensures 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 set includes:
4x Luxen Solar 450W Bifacial Solar Module TopCon Full Black
1x EcoFlow STREAM Ultra 1.92kWh all-in-one storage system 4 MPPT
1x EcoFlow Three-Phase Smart Meter
1x - 5x EcoFlow STREAM AC Pro 1.92 kWh Storage LiFePO4 2300W (optional)
Optional:
Solar module carrier for flat roof mounting, tilt adjustable, or
Solar module holder for balcony railings Adjustable angle
