Which outcome occurs when a photovoltaic charge controller's freewheeling diode circuit fails short?

💡 Explanation

Excessive panel back-current flow occurs because a failed-short diode allows reverse current through the photovoltaic array, bypassing blocking functions; therefore, the panel overheats significantly rather than the battery overcharging assuming functional MPPT.
