PV plant parameters

1. Press MENU key, move the cursor onto EFF by using the
arrow keys (,) and confirm with ENTER. The display
shows the values of the output electrical parameters of
the photovoltaic generator (DC side).
2. Press the ENTER key. The instrument shows the
following options: "Set PV plant" and "Set Instrum".
3. Use the arrow keys (,) to select "Set PV plant" and
confirm with ENTER. The instrument shows the following
screen:
4. By means arrow keys ( , ) the herewith parameters
are set:
 Pmax  maximum nominal power of the PV
installation expressed in kW
 Gamma  coefficient of variation of power with the
temperature, standard parameter of PV module
(range: -0.3  -0.5%/°C typical)
 Noct  nominal working temperature of a PV cell,
standard parameter of PV module (range: 42  48°C
typical)
 Te, Tc  set of default values of environmental
temperature and PV module temperature. These
values are considered by the meter only without the
auxiliary probe connected to emote unit SOLAR-02
 Corr. Type  set the corrective term Ptpv for DC
efficiency calculation and for maximum DC efficiency
visualization (see § 5.2.3)
