中车株洲电力机车研究所有限公司研制的500 k W光伏逆变器宽度仅1 m(简称“米柜”),为光伏发电行业目前最高功率密度等级逆变器产品。2016年3月30日,该逆变器通过了业内最严格的效率测试标准CGC/GF 035:2013《光伏并网逆变器中国效率技术条件》的认证,中国加权效率超过98%,获得最高效率等级“A”。中国加权效率综合考虑了中国气候条件的影响,通过不同输出功率条件下逆变器的发电效率配以
The 500 kW photovoltaic inverter developed by Zhuzhou Electric Locomotive Research Institute Co., Ltd. has a width of only 1 m (referred to as “rice cabinet” for short) and is currently the highest power density inverter in the photovoltaic power generation industry. On March 30, 2016, the inverter passed the certification of China’s most stringent efficiency test standard CGC / GF 035: 2013 “Technical Conditions of China’s Efficiency of Photovoltaic Grid-tied Inverters”. The weighted efficiency of China reached more than 98%, reaching the highest level Efficiency level “A ”. China’s weighted efficiency takes into account the impact of climatic conditions in China. By matching the power generation efficiency of the inverter with different output power
