CPS PID effect prevention technology awarded Chinese utility innovation patent
In September, “a method to prevent PID effect on PV panels” declared by Chint Power Systems was awarded with the utility innovation patent by Chinese Intellectual Property Office. Meanwhile, this technology submitted as a patent for invention is in the process of audit now.
"A method to prevent PID effect on PV panels” is an innovative utility solution to the PID (Potential Induced Degradation) effect that is ubiquitous on PV panels. This patent aims to prevent the PID effect on PV panels from the PV power system. When the PV inverter is in normal operation, the voltage of PV panel is measured to monitor the inverter’s working condition. When the PV inverter stops working, the reverse voltage is imposed on PV panels to essentially prevent the PID effect, extend the service life of PV panels and save the PV system costs.
Chint Power Systems, which is the new technology enterprise, high and new technology achievement transformation company holds the principle that science prospers enterprise with research and innovation. Chint Power Systems highly focuses on the patent acquisition by propagating the company culture of technology innovation and revolution among staff. Energy Balancer, which is the patented product, has been widely applied in many PV systems domestically and abroad. In the whole PV system, it plays a vital role in keeping the conversion efficiency stable.
The patent acquisition has proved the innovation ability of Chint Power Systems. The company will further complete the intellectual property protection system, develop the innovation mechanism, take advantage of intellectual property and continuously strengthen the kernel competence.
