This spot check is based on the requirements of NB/T 32004-2013 "Photovoltaic grid-connected inverter technical specifications" and other standards, protection connection, rated input and output, conversion efficiency, harmonics and waveform distortion of photovoltaic grid-connected inverter products. Multiple items such as power factor, DC component, over/under voltage protection, operating overvoltage, and power-frequency withstand voltage of solid insulation were tested. Gudwei GW5000D-NS single-phase two-way products have excellent performance in the sampling process, which proves that its stable, efficient and reliable product performance is worthy of consumers' trust.
In recent years, under the stimulus of a series of favorable policies of the country, the photovoltaic power generation industry has ushered in the spring, but it is worth noting that according to the overall situation of the spot check of the PV inverter by the AQSIQ, the pass rate of the spot check is not optimistic. This time, Goodwin successfully passed the national sampling inspection, hoping to enhance consumers' confidence in PV inverters. At the same time, it also encouraged every employee of the company to make persistent efforts to provide customers with better products and services.
In addition, in terms of enhancing product reliability, Gu Dewei constantly seeks the support of well-known certification institutions at home and abroad. In addition to safety certification, Gu Dewei products are sent to Germany for VDE reliability testing; through continuous strengthening of laboratory system construction Gu Dewei is now qualified as a TÃœV Rheinland laboratory and has been approved as a provincial engineering technology research and development center. Since its inception, Goodwin has been focusing on the development and production of photovoltaic inverters, always putting quality at the ** position. Committed to providing stable, reliable and high quality inverter products for photovoltaic green business.
