Kampusareena solar power plant inverters

Electrical measurements from the 4 inverters of the solar power plant of Kampusareena. The maximum power production of the solar plant is 57 kW. The power output goes to the top floor ventilation machine room. Collected measurements include frequency, current, voltage, power and energy.

The inverters are the following:

  • For the west wall 1x SMA STP8000TL (8 kW)
  • For the southwest wall 1x SMA STP15000TL (15 kW)
  • For the southeast wall 2x SMA STP17000TL (2 x 17 kW)

Most of the data is collected with a one second interval. However there is some static data about the inverters that is fetched only once per day or whenever the collector is restarted. These values are marked as read once in the available measurements list.


  • Data collected before 2018-08-08 may contain erroneus data in the form of large negative numbers like -2147483648. This is because the collection system misinterpreted the value signaling that there were no data since the inverter was not operating. This often occurred during night time.

See the ProCem project for general information about how the measurements are stored and how they can be used. See the Kampusareena group for general information about the building.
