CALCULATIONS FOR CURRENT CARRYING CONDUCTORS
#5 Aggregate Panel Output Wire Ampacity Calculation
Output Circuit OCP Calc.
(Inverter Imp)*(Total # of Inverters)*(1.25) = 86.25 A
Agg Panel Imax (Inverter Imp)*(Total # of Inverters) = 69.0 A
AWG #3, (Derated Amps=100)*(Temp Der.=0.91)*(CND Fill Der.=1) = 91.0 A
91.0 A > 69.0 A, therefore AC wire size is valid.
#4A,4B Junction Box 1 Output Wire Ampacity Calculation
Using largest ampacity of separate branches for calculation = 16.0 A
AWG #10, (Derated Amps=35)*(Temp Der.=0.71)*(CND Fill Der.=0.8) = 19.9 A
19.9 A > 16.0 A, therefore AC wire size is valid.
#3 Microinverter Output Wire Ampacity Calculation - Branch 1, 2, 3, 4, 5
Branch Output Circuit OCP Calc. (Inverter Imp)*(# of Inverters)*(1.25) = 20.0 A
Using largest ampacity of separate branches for calculation
Branch Output Circuit Imax (Inverter Imp)*(# of Inverters) = 16.0 A
AWG #12, (Derated Amps=25)*(Temp Der.=0.91)*(CND Fill Der.=1) = 22.75 A
22.75 A > 16.0 A, therefore AC wire size is valid.
