What does 'Open Circuit Voltage' (Voc) signify when wiring multiple rooftop solar panels into an MPPT controller?

Next

 Correct IncorrectThe maximum voltage the solar array produces when disconnected with no load. In series wiring, voltages add together and must never exceed the controller's maximum Voc limit in freezing temperatures.

What does 'Open Circuit Voltage' (Voc) signify when wiring multiple rooftop solar panels into an MPPT controller?

• The voltage when the panels are covered in blankets
• The battery voltage at 50% charge
• The power consumed by the display backlight
• The maximum unloaded voltage output of the array, which must never exceed the charge controller's rated input limit
