20.5 kW Hybrid Power Plant
Department of Converters for Renewable Energy Acquisition
At the company’s new headquarters located at 28–30 Aleksandrowska Street in Toruń, there is a 41.2 kWp hybrid power plant based on our proprietary converters:
- PS100PV/5.5 kW – single-phase photovoltaic inverter, 5.5 kW
- PS100H/5.5 kW – single-phase hybrid (solar-wind) inverter, 5.5 kW
- PS300/PV/10 kW – three-phase photovoltaic inverter, 10 kW
This power plant serves as a laboratory for the Department of Converters for Renewable Energy Acquisition.
The source of electrical energy is 139 photovoltaic panels with a total output of 38.2 kWp and a horizontal-axis wind turbine rated at 3 kW.
The panels are installed on the roof of the production hall (Power Plant I) and on the ground (Power Plant II).
The wind turbine is located in the southern part of the headquarters on a 15-meter-high mast.
