A 1785 PV Remote WL Preface

1 Preface
The PV Remote WL is a professional hand-held accessory intended to perform temperature
and solar irradiance measurements.
PV modules and connection terminals for measuring are often not on the same location. For
examples PV modules are on the roof and connection terminals are at the inverter, inside the
building. With the PV Remote WL, environmental parameters can be measured while electrical
parameters are measured with the instrument on another location. The clocks of main
instrument and PV Remote WL can be synchronized. This enables an easy pooling of data
measured at the same time after the tests are finished.
Contemporary measurement of electrical and environmental values is demanded in some
standards for calculation of efficiency of PV systems.
The graphic display with backlight offers easy reading of results, indications, measurement
parameters and messages.
