System Design Calculations Report (Non -Code) 2.1. PV Source Clrcult Voltage Range Test This test confirms that the voltage of the PV Source Circuit will always remain within the DC input voltage window of the system's inverter, microinverters, or power optimizers. 2.1.1.

String Voc at Low Temperature 42.25V The module Voc (39.48V) will Increase to 42.25V at the design low temperature (09C). (0°C - 25°C) X-0.111V1C + 39.48V = 42.25V The total Voc for the string is 42.25V. 42.25V X 1= 42.25V B. String Vmp at High Temperature 27.97V Estimated cell temperature equals the design high temperature (33°C) plus 300C (the estimated difference between ambienttemperalures and the cell temperature for a roof mount with tilt). 330C + 300C = 630C The module Vmp (32.19V) will drop to 27.97V at the design high temperature (33°C). (63°C - 25°C) X-0.111V/C+ 32.19V = 27.97V The total Vmp for the string is 27.97V. 27.97V X 1= 27.97V Validation Tests The minimum Vmp must exceed the minimum PASS input voltage of the connected device 27.97V> BV=true The maximum Voc must not exceed the max input PASS voltage of the connected device 42.25V <48V = true
