5.7.2.3. Result for data of RecMPP type
This page shows the values of the parameters measured and calculated during the test /
recording phase together with the MPP300 unit (optional).
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 recognizes the condition of “ steady irradiation ” for a
detected measuring point when, with AVERAGE irradiation value measured
by the pyranometer > minimum threshold set (see § 5.3.3.3),
the difference
between the maximum and minimum irradiation values measured is <
20W/m
2
(with IP

1min)
If there are more points satisfying the above-mentioned condition, the
instrument considers the one in which the combination of the performance
values takes the maximum value.

Please see § 5.3.2 and § 10.1 for further information about the mathematic relationships
used.
1. Press the
F2 , F3 and F4 keys to respectively display the Total, DC and AC input and
output values of the inverter relevant to the maximum performance point.
2. Press the
ESC key (or the smart icon ) to exit the function and go back to the
“Recording Analysis” page (Fig. 134).
