6.7.3. Carrying out IVCK Tests with remote unit
Irradiance and temperature measurements (if the instrument is set in temperature
measuring mode “MEAS”) with the aid of a remote unit SOLAR03 connected via
Bluetooth to the instrument are recommended in case of unstable irradiance conditions
or if a comparison is necessary with the module’s rated values declared by the
manufacturer.
CAUTION
Check that no remote unit is currently activated. In case it is not, please
carry out the connecting procedure described in § 6.2.
The maximum voltage between inputs P, N, E and C is 1500VDC. Do not
measure voltages exceeding the limits given in this manual.
Do not perform tests on PV modules or strings connected to the DC/AC
converter.
The maximum temperature which can be tolerated by the instrument is
40°C
Standard IEC/EN62446 requires that measurements are performed string by
string. Even if the instrument is designed to manage inrush current for single
strings or strings connected in parallel, we recommend testing one string at
a time accordin
to the standard’s prescriptions.
The instrument can operate combined with remote unit SOLAR03 in one of the following
modes:
Presence of remote unit SOLAR03 active and connected the instrument directly
provides the results of measurements @STC
Presence of remote unit SOLAR03 active, connected and recording: the
instrument directly provides the results of measurements @STC
Modes 1 and 2 are basically the same in case the instrument and the remote unit
SOLAR03 are directly connected.
Presence of remote unit SOLAR03 active, recording, NOT connected the
instrument provides the results of measurements @OPC with no outcome, then
automatically and simultaneously converts them to @STC only after data have been
transferred from the remote unit at the end of recording and upon the next
connection.
