Note: This is a demo version of the dataset.
Overview
This dataset contains electrical measurements from the four inverters of the Kampusareena building's solar power plant. The plant has a maximum power production capacity of 57 kW, with the power output directed to the top floor ventilation machine room.
Solar Power Plant Specifications
- Total Capacity: 57 kW
- Location: Kampusareena building, Tampere University
Inverter Configuration
The solar power plant consists of four inverters distributed across three walls:
- West Wall: 1x SMA STP8000TL (8 kW)
- Southwest Wall: 1x SMA STP15000TL (15 kW)
- Southeast Wall: 2x SMA STP17000TL (2 x 17 kW)
Measurements
The dataset includes various electrical parameters, such as:
- Frequency
- Current
- Voltage
- Power
- Energy
Data Collection Frequency
- Most data: 1-second interval
- Static inverter data: Once per day or upon collector restart (marked as "read once" in the available measurements list)

Important Notes
- Data Quality Issue: Data collected before 2018-08-08 may contain erroneous values (large negative numbers like -2147483648). This occurred when the collection system misinterpreted the "no data" signal from non-operating inverters, often during nighttime.
