Kehua has supplied its inverters for a 10MW solar system at Promet-Plast, a medical supply manufacturer in Poland aiming for zero-carbon emissions. The factory's innovative multi-energy system not only harnesses solar power but also integrates wind energy, hydrogen production, and lithium battery storage, achieving 100% renewable energy usage. Located in Olawa, Poland, this project utilizes 83 units of SPI125K-B and SPI100K-B inverters with 20kV medium voltage technology. By implementing Kehua's inverters, the project is estimated to generate 8,800 MWh of electricity annually, providing significant cost savings for Promet-Plast. Kehua's SPI100-125K-B inverters support up to 9 MPPTs and 18 strings, featuring excellent string expansion capability that minimizes energy waste due to inconsistent PV array orientation. The intelligent sub-array communication box allows for effective system monitoring and management, enhancing user experience and control over each inverter. Moreover, Kehua's inverters boast multiple protection strategies, including temperature, surge, and AC short circuit protection, ensuring system safety at an IP66 level. Overall, Kehua's solutions not only optimize solar energy utilization but also meet technical standards and enhance the reliability of renewable energy systems.
