2.2 Introduction

Photovoltaics are a fiercely competitive market. The primary focus
of the end user is on the annual energy yield of their photovolta-
ic system. The TRI-KA characteristics analyser with the wireless
TRI-SEN stands out due to its simple operation, its flexible mobil-
ity and its excellent price-performance ratio. It provides installers
with a quality control system for documentation of their PV
system data.
The TRI-KA with the TRI-SEN is an intelligent measuring and
documentation system that is indispensable for a professional
installation and maintenance of a PV system. It facilitates the
correct installation of a PV system and allows a comprehensive
documentation of the system quality.
The measuring system is based on the two portable measuring
instruments TRI-KA and TRI-SEN. It can be used to carry out the
following measurements and analyses:
TRI-KA
• Open-circuit voltage U
OC
• Short-circuit current I
SC
• I/U characteristic curve
• MPP voltage U
MPP
• MPP power I
MPP
• MPP output P
MPP
• STC characteristic curve
• STC values
• Fill factor
• Ideal characteristic curve of module manufacturer
TRI-SEN
• Global irradiation at module level
• Cell temperature
• Angle of inclination of the sensor
To convert the characteristic curves under standard test con-
ditions, the measured data are wirelessly transferred from the
TRI-SEN to the TRI-KA. This data transfer process enables a syn-
chronous measurement of the characteristic curves and the solar
irradiation irrespective of the location.
