Huawei&#8217;s Smart I-V Curve Diagnosis solution replaces this manual process with automatic online scanning technology. The system actively analyzes voltage-current curve deviations to detect abnormalities early, enabling operators to perform predictive maintenance efficiently.  <\/p><\/blockquote>\n<h2 data-path-to-node=\"10\">Key features<\/h2>\n<ul data-path-to-node=\"11\">\n<li>\n<p id=\"p-rc_2330bd5c84591606-421\" data-path-to-node=\"11,0,0\">One-Click Operation: The entire I-V curve scanning process across all strings is executed completely online and remotely.
