The critical engineering goal is to ensure the total Vmp (Voltage at Maximum Power) of the solar string falls within the inverter&#8217;s peak efficiency window, and the total string Voc (Open Circuit Voltage) remains safely below the inverter&#8217;s maximum DC input at the site&#8217;s lowest recorded temperature.<\/strong><\/p>\n<h2>1.
