To correctly size a solar pump inverter for an existing AC pump, you must match the inverter\u2019s Rated Output Current to the motor\u2019s Full Load Amps (FLA), typically applying a 1.15x safety margin. Sizing by kW alone is a common field error that leads to premature IGBT failure. Additionally, the PV array configuration must ensure the Vmp stays within the inverter’s MPPT window while the Voc never exceeds the maximum DC input voltage at the site\u2019s lowest temperature.<\/strong><\/p>\n \u0641\u064a \u0627\u0644\u0645\u064a\u062f\u0627\u0646\u060c \u0646\u0631\u0649 \u0641\u064a \u0643\u062b\u064a\u0631 \u0645\u0646 \u0627\u0644\u0623\u062d\u064a\u0627\u0646 \u0641\u0646\u064a\u064a \u0627\u0644\u062a\u0631\u0643\u064a\u0628 \u064a\u0642\u0648\u0645\u0648\u0646 \u0628\u062a\u0648\u0635\u064a\u0644 \u0645\u062d\u0648\u0644 \u0637\u0627\u0642\u0629 \u0628\u0642\u062f\u0631\u0629 7.5 \u0643\u064a\u0644\u0648\u0648\u0627\u0637 \u0628\u0645\u0636\u062e\u0629 \u0628\u0642\u062f\u0631\u0629 7.5 \u0643\u064a\u0644\u0648\u0648\u0627\u0637 \u0648\u064a\u062a\u0633\u0627\u0621\u0644\u0648\u0646 \u0639\u0646 \u0633\u0628\u0628 \u062a\u0639\u0637\u0644\u0647\u0627 \u0628\u0633\u0628\u0628 \u0627\u0644\u062a\u064a\u0627\u0631 \u0627\u0644\u0632\u0627\u0626\u062f.<\/p>\n \u0627\u0644\u062d\u0642\u064a\u0642\u0629:<\/strong> Power ratings are nominal.
