4 DIAGNOSTICS
Group of parameters number [2]
Diagnostic information (quantities and states).
4.1 Fotocontrol / PGE
Group of parameters number [744]
Quantities relevant to the control of PV power plant or peak energy generator (PEG).
MENU \ DIAGNOSTICS \ FOTOCONTROL / PGE
Name [ID]
Description
Dim.
Sum DC
currents
[634]
Sum of DC currents flowing from all PV or battery strings. For FOTO CONTROL inverter
which do not have the extension module for DC current measurement this value is
calculated as a sum of all DC strings. The check of sum strings can be turned on by
String check [747] (page 36).
A
Voltage per
cell [477]
The voltage of single photovoltaic (PV) panel or one cell of battery. It is calculated as the
quotient of the DC link voltage and the parameter Number of panels/cells [507] (page
35).
V
DC input
power [632]
Instantaneous input power (power of solar panels). It is calculated as a product of DC
Voltage [46] (page 19) and Sum DC currents [634] (page 15).
W
Inv.
efficiency
[859]
Inverter efficiency calculated from the ratio of Active grid power [70] (page 17) and DC
input power [632] (page 15) in percent. When the power is lower than 10% of the Max.
gen. power [808] (page 45) , this value is not calculated, but set to 99.9%. Permament
decrease of the efficiency can be caused by malfunction of inverter components or
incorrect configuration. The efficiency can be guarded by the optional fault set by [864]
(page 36).
%
String
unbalance
[928]
Determines the percentage error of string currents. This unbalance is calculated as the
difference between the lowest and highest value of the currents. Short-term unbalance
may arise due to uneven lighting of PV panels in cloudy weather. Long-lasting unbalance
may be caused by uneven number of PV panels installed in the strings, permanent
damage or by partial shielding of the panels. This test can be turned on/off in String
check [747] (page 36).
%
PEG BAT
SOC [1166]
PEG battery state of charge in percents of PEG Nom. Ah [1164] (page 35).
