NOTICE
Incorrectly dimensioned solar system.
If the solar system is dimensioned incorrectly,
this may damage the inverter.
► Always take the technical specifications of
the inverter (input voltage range, maximum
current and maximum input power) into ac-
count when calculating the number of solar
modules.
NOTICE
Overheating of the DC connections.
Exceeding the maximum current can cause the
DC connections to overheat and catch fire.
► Always take the maximum current of the DC
connections into account when planning the
installation.
