Recently, our company commissioned the Jiangsu Institute of Electronic Information Product Quality Supervision and Inspection (Jiangsu Information Security Testing Center) to conduct IEC61000 standard testing on two of our products, the intelligent sun tracker controller and intelligent communication box. The testing of this standard indicates that the products have high quality stability and reliability, and both products have reached international leading levels. During the test, the photovoltaic tracking controller TCU works in conjunction with the NCU communication box and motor. After the NCU communication box and TCU are identified and connected, the entire system is judged to be functioning properly by the motor. The inspection items include RF electromagnetic field radiation immunity, RF field induced conduction disturbance, electrostatic discharge, and other items. The conclusion is that the test has passed, once again proving that our solar tracking controller can withstand multiple tests.
