Sunways AT 5000 - Connection of Temperature and Irradiation Sensor

43
Connection of temperature and
irradiation sensor
The optional addition of an irradiation
sensor (model Si-01TC-K from Ingenieur
-
büro Mencke & Tegtmeyer) with an
integrated PT-100 temperature sensor for
temperature measurement enables the
acquisition of irradiation data and the
corresponding module temperature and
storage in the internal data memory as
a 5-minute mean value. This additional
measuring unit helps analyse the system
output. Based on the values, any errors
on the PV generator, e.g. shading or fail
-
ure of solar cells, can be detected.
