4 FIELD OF APPLICATION AND GENERAL DESCRIPTION OF
THE PARALLEL STRING PANEL (PSP)
Figure 4-1: PVI-STRINGCOMB(-S)
The PVI-STRINGCOMB(-S) and its variants (Figure 4-1) are devices designed
exclusively for parallel connection of the photovoltaic field strings, allowing for
protection in the case of breakdown.
Besides connecting the strings, they allow the electrical quantities and other type
of quantities for the entire photovoltaic field to be monitored through the following
checks:
−
Reading the total voltage of the field.
−
Checking the operation of the internal fuses, to protect the photovoltaic
panels.
−
Checking of the status of the internal protection against overvoltage (DC
side).
−
Temperature check.
−
General checks on the surrounding environment through external sensors.
