摘　　要：文章以4个光伏阵列单元的通讯故障为例,介绍了光伏阵列单元在并网过程中遇到的问题。工程实践表明,汇流箱与光伏智能终端之间的RS485通信受工程接地、逆变器干扰、接线形式、通信布线和逆变器室设计施工影响很大。文章分析了问题的原因,提出了解决方案。This article introduced the problems of communication in photovohaic grid in four photovoltaic array elements. Communication interface RS485 between confluence box and photovoltaic intelligent terminal, was seriously impacted by engineering grounding, inverter interference, wiring pattern, communication wiring, inverter room design and construction. The paper analyzed the reasons of the problems and put forward the solutions
