5.7.2.2. Result for data of RecPV type
This page (not available for RecPV* data as these recordings are, in fact, incomplete)
displays the values of the parameters measured and calculated during the testing /
recording phase. In particular, the instrument:

Do not show any results if do not exist on the PV installation a “stable irradiance ”
condition more than the minimum irradiance threshold (see § 5.3.3.3)

Display the best performance values if during the recording, the Irradiance values
reached the “ stable ” condition and its values were higher than the minimum irradiance
threshold (see § 5.3.3.3)
CAUTION
The instrument acknowledge the “ stable irradiance ” condition for a detected
point of measure when, with MEDIUM value of irradiance measured by the
pyranometer > set minimum irradiance threshold (see § 5.3.3.3),
the
difference between Maximum and Minimum values of irradiance in the
same point is < 20W/m

(with IP

1min)
If more points satified the a.m. conditions, the meter consider the point
correspondent to a maximum efficiencies combination
The instrument displays the following parameters:


Photovoltaic panel performance
Vdc

DC voltage at inverter input
Idc

DC current at inverter input
Pac

AC power at inverter output
Pf

Power factor at inverter output


The display of the Tenv or Tpv values in blue
indicates that the mentioned values are the
default ones, as the ones measured by SOLAR-
0x are not available (see § 5.3.2.4
).
