Calculations
A. 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
