VooluValdaja - Technical Datasheet


  1. Primary Purpose: 
    1. To optimize energy production (e.g., solar or wind) and consumption to maximize savings or profit. It achieves this by monitoring production, consumption, battery levels and NordPoolSpot prices and enabling end-users to participate in flexibility markets (mFRR, aFRR).
  2. Secondary Functionality: 
    1. Provide an alternative access for monitoring and control, allowing users to disconnect their energy production equipment from the manufacturer's cloud. 
    2. Integrates all components of an energy production/consumption system (Solar, EV Charging, HVAC), treating it as a unified entity, offering a holistic energy management solution.
