This can happen because the inverter may still contain stored energy, long PV cables can create a small induced signal, or connected equipment may have a small leakage current.<\/p>\n<p>If the system still carries a significant operating current or continues to power connected equipment after the isolator is turned off, inspect the wiring, connected devices, and the isolator switch to ensure everything is functioning correctly.<\/p>\n<h4><strong><b>Q4: <\/b><\/strong><strong><b>Can YRO provide customized branding?<\/b><\/strong><\/h4>\n<p>Yes.<\/p>\n<p>OEM logo, packaging, and product customization are available for distributors and equipment manufacturers.<\/p>","protected":false},"excerpt":{"rendered":"<p>YRO DC Isolator Switch is designed for safe electrical isolation in solar PV\u00a0systems, providing reliable disconnection between PV modules, inverters, and DC circuits during installation, maintenance, and emergency situations.<\/p>","protected":false},"featured_media":5974,"template":"","meta":{"_acf_changed":false,"footnotes":""},"product_category":[70,71],"product_filter":[],"class_list":["post-5973","product","type-product","status-publish","has-post-thumbnail","hentry","product_category-isolator-switch","product_category-dc-isolator-switch"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.yroele.com\/de\/wp-json\/wp\/v2\/product\/5973","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.yroele.com\/de\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.yroele.com\/de\/wp-json\/wp\/v2\/types\/product"}],"version-history":[{"count":5,"href":"https:\/\/www.yroele.com\/de\/wp-json\/wp\/v2\/product\/5973\/revisions"}],"predecessor-version":[{"id":5993,"href":"https:\/\/www.yroele.com\/de\/wp-json\/wp\/v2\/product\/5973\/revisions\/5993"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.yroele.com\/de\/wp-json\/wp\/v2\/media\/5974"}],"wp:attachment":[{"href":"https:\/\/www.yroele.com\/de\/wp-json\/wp\/v2\/media?parent=5973"}],"wp:term":[{"taxonomy":"product_category","embeddable":true,"href":"https:\/\/www.yroele.com\/de\/wp-json\/wp\/v2\/product_category?post=5973"},{"taxonomy":"product_filter","embeddable":true,"href":"https:\/\/www.yroele.com\/de\/wp-json\/wp\/v2\/product_filter?post=5973"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
