•
Check the cables for correct polarity.
•
Ensure the DC Switch is set to position "0" before connecting the connectors.
•
The system voltage must not exceed the maximum input voltage of the inverter (see
Type plate). PV modules are suitable for a maximum system voltage according to IEC
61730 Class A.
Overvoltage will destroy the inverter.
If necessary, check the string layout to avoid an electrical surge.
•
Any type of contamination (dust, moisture, etc.) negatively influences the
functionality of the connector system over the intended period of use. It is therefore
essential to avoid contamination during the connector assembly and installation.
•
The voltage in the DC cables correlates with the intensity of the solar radiation onto
the PV array. It is lower in the morning and evening hours or when the PV panels are
shaded.
