Always use meters rated <strong>CAT III 1500V<\/strong> or higher for string-level PV work.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why is CAT III 1500V important for solar maintenance?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">CAT III 1500V ensures the meter can safely withstand high-energy transients present in PV strings, combiner boxes, and inverter inputs.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is a clamp meter necessary for solar PV maintenance?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes.
