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
2
(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:
DC 
FV 
 AC
Legend of parameters for single-phase PV systems:
PRp Performance Ratio (active power)
Pdc  DC power at inverter input

DC
 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

AC
 Inverter performance
Vac  AC voltage at inverter output
Iac  AC current at inverter output
Irr  Solar irradiation
Pnom  Nominal power of the photovoltaic system
Tpv  Temperature of photovoltaic panels
Tenv  Environmental temperature
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).
