Group of parameters number [663]
Settings of the inverter parameters, load, control, command and other components and functions of the
inverter.
7.1 FOTOCONTROL / PEG
Group of parameters number [4]
Parameters for setting functions of the inverter, intended for deployment in photovoltaic power plants, where
power source are DC photovoltaic (PV) panels or peak energy generators (GSE) with battery as a source of
DC voltage.

Description
Def.
Nr. paral. strings
[701]
Number of paralelly connected strings. String is a section of several serialy
coupled DC voltage sources (PV panels or batteries).
1
0 ÷ Nr. of strings
10
Inverter monitors the string currents by the extension module for string current
measurement. This value determines the number of measured currents. [735] (page 15).

(str. 14) by product type.
Number
of
panels/cells [507]
Represents the number of PV panels coupled in series in one string, or the
number of batteries coupled in series (GSE).
10.0
0.1 ÷ 1000.0
This parameter determines the ratio of calculating the value of Voltage per cell [477]
(page 15) from the DC link voltage. When serial-parallel coupling is used, this value is
represented as the number of panels/batteries in one block (string).
Vdc AC contactor

Minimum voltage on DC input power terminals to switch on the AC contactor.

Switching on og the AC contactor is an essential condition for START of the FOTO
CONTROL inverters and production of energy. Value of this parameter should be close to
the Maximum Power Point. Too low values can cause switch on-off cycles or fault during
start-up of the inverter.

Autodetection
voltage [805]
Turning on the mode of autotuning of Vdc AC contactor on [791] (page 35).
When this autodetection is turned on, inverter automatically adjusts the value of
Vdc AC contactor on [791] (page 35), to suppress the frequent start and stop of
the inverter. Autodetection measures the DC voltage right after the auto off after
decrease of generated power below the value of Run condition [683] (page 40).

switch off [504]
Allowing switching off of the AC contactor during the all faults when the Auto off
[681] (page 40) is turned on, for FOTO CONTROL family inverters.
When the AC contactor switch off is disabled, its switch off can occur during the
fault E5-DC undervoltage (page 32) only.
