METREL MI3115 - On-Line Synchronization of Environmental Data between PV Remote WL and Instrument

MI 3115 PV Analyser
Single tests
44
The best working practice is to establish a permanent on-line wireless connection between
the A 1785 PV remote WL and the instrument during the tests.
If the wireless connection is established between the PV remote WL and the instrument
during the PV test the environmental data from the remote unit will be automatically sent
to the instrument and considered in the test.
See On-line synchronization of environmental data between PV Remote WL and
instrument.
If there is no wireless connection with the PV remote WL during the PV test, it is possible to
log the environmental data with the A 1785 PV Remote WL and synchronize the
environmental data later. For the measurement on the instrument, manually entered
environmental data will be considered, if data from PV Remote WL is not available. The
measured environmental data with PV Remote WL, can be downloaded to the instrument
and synchronized with selected saved measurements anytime later.
See Synchronization of environmental data between PV Remote WL and instrument after
the test.
6.4.1 On-line synchronization of environmental data between PV Remote
WL and instrument
Following data measured with PV remote will be automatically synchronized during the
measurement on the instrument:
Irr
Irradiance at time of measurement
Tcell
PV cell temperature at time of measurement
Tcell (5 min)
PV cell temperature 5 min before test
Tcell (10 min)
PV cell temperature 10 min before test
Tcell (15 min)
PV cell temperature 15 min before test
Tamb
Ambient temperature at time of measurement
Note
• Only environmental data available at a time of measurement are sent to
instrument. Data like Tcell (5 min), Tcell (10 min) and Tcell (15 min) are available
after specific time after start logging.
Procedure
In single test starting menu switch Environmental data parameter to Remote.
Before the test, check that Wi-Fi connection between PV remote WL and instrument is
established.
PV remote WL must be logging environmental data. For more information see PV Remote
WL Instruction manual.
