PV Connection
4.4.1 Connecting PV to the Inverter
Cable Requirements:
Minimum Insulator Voltage
10 AWG – 6AWG (Max) (6 mm
2
– 16 mm
2
) 600V
Consult with your installer to ensure that appropriate cable sizing is used due to various factors such as
voltage drop and VOC.
Reminder
Verify the lowest ambient temperature of the installation location. The rated VOC on the solar module
nameplate is obtained at STC (77°F/25°C). As the ambient temperature drops, the solar module VOC
increases. Please ensure the maximum solar string voltage, corrected at the lowest temperature, does
not exceed the inverter’s maximum input voltage of 600V.
