5.2.3.2. Multi-MPPT photovoltaic system screen – Three-phase output
When SOLAR300N is in connection with MPP300, the display shows the following
parameters:
DC
PV 
 AC
PARAMETER CAPTION:
PRp:  Performance Ratio (ref. active powers)
Pdc  Inverter input DC power

DC
 Photovoltaic panel performance
Pac  Inverter output AC power

AC
 Inverter performance
Pnom  Photovoltaic system rated power
If the remote unit SOLAR-02 is connected to the
MPP300, the following values are also available:
Irr  Solar irradiation
Tpv  Default photovoltaic panel temperature
Tenv  Default environmental temperature
When Tenv or Tpv values are displayed in blue, it
means that these values are different from the
default ones, as those measured by SOLAR-02
are not available (see §5.3.2.4).

Pressing the F3 (DC) key displays the following screen:
PARAMETER CAPTION:
Vdcx  Inverter input DC voltage
Idcx  Inverter input DC current
Pdcx  Inverter input DC power
x=1,2,3 according to the number of MPPTs set

Pressing the F4 (AC) key displays the following screen:
PARAMETER CAPTION:
Vacxy  Inverter output phase x-phase y AC
voltage
Iacx  Inverter output phase x AC current
Pacx  Inverter output phase x AC power
x=1,2,3 - Phases of the system AC side

5.2.4. Value screens for NPV systems
Further in this manual the expression “Page x/y” will be used, to indicate that the current page
number (x) and the total number of pages (y) depend on the instrument settings. Pressing
cyclically F1 key or arrow keys left of right the meter shows the other pages of TRMS
measured values which are described in below pictures. Pressing ESC key to go back to
