7.11 LED operation and fault display
Three light-emitting diodes (LEDs), which display the operational state of the solar
inverter, are attached on the front:
Operation (A)
Earth Fault (B)
Failure (C)
● LED (A), green: „Operation“ displays the
operational state.
● LED (B), red: „Earth Fault“ displays an
insulation resistance fault or PV grounding
(GND) fault on the DC side.
● LED (C), yellow: „Failure“ displays existing
faults internally or externally and whether
the grid feed-in operation has been inter-
rupted.
