Abstract
本申请公开了一种逆变器、光伏发电系统及除湿方法，逆变器包括：透气阀和气流传动设备；透气阀安装在逆变器的机柜腔体的表面上；控制器和气流传动设备位于机柜腔体内；透气阀上设有透气膜；气流传动设备在以下至少一项预设条件成立时，将机柜腔体内的空气吹向透气膜，使机柜腔体内的空气通过透气膜溢出机柜腔体；至少一项预设条件包括：逆变器运行、机柜腔体内的湿度大于预设湿度和机柜腔体内的温度大于预设温度中的至少一项或多项。在逆变器的机柜腔体内设置气流传动设备，将机柜腔体内的高湿空气吹向透气阀的透气膜，使机柜腔体内的高湿控制通过透气膜溢出机柜腔体，强制机柜腔体内的空气排出，降低机柜腔体内的湿度，保护逆变器内电气元件。
