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).
If the remote unit SOLAR-0x is connected to the
main, the following values are also available:
Irr

Solar irradiation
Pnom

Nominal power of the photovoltaic system
Tpv

Measured temperature of the photovoltaic

panels
Tenv

Measured environmental temperature

5.2.3. Screen of photovoltaic systems with multi-MPPT inverter (only with MPP300)
For the sake of simplicity, further in this manual, the word “string” will be used, although
often the term “photovoltaic field” would be more correct. From the point of view of the
instrument, the management of a single string or of more parallel strings (photovoltaic
field) is identical.
The instrument SOLAR300N, used together with remote units SOLAR-02 and MPP300
(
optional ), allows testing PV systems characterized by inverters with 1 or more MPPTs
connected to the relevant PV fields (consisting in PV modules with the same direction and
inclination) and single-phase or three-phase output.
The remote unit MPP300 communicates with SOLAR300N (to manage data setting,
synchronization and download) through the USB connection cable and with the remote
unit SOLAR-02 (for recording irradiation and temperature values) via a wireless
radiofrequency (RF) connection, which is active up to a maximum distance of 1m between
the units.
For further details on the use of MPP300, please see the unit’s user manual.
