Warning message.
• LED (A), green: „Operation" displays the
operational state.
(A)
• LED (B), red: „Earth Fault" displays an insula-
tion resistance fault or PV grounding (GND)
fault on the DC side.
(C)
• LED (C), yellow: „Failure" displays existing
faults internally or externally and whether the
grid feed-in operation has been interrupted.
EXPLANATION
The input voltage (UPV) is lower than 100 V.
The solar inverter is not feeding power to the grid.
Input voltages:
UPV: 100 V to 150 V
(self test ongoing).
Starting conditions are tested.
Normal operational state:
UPV: 150 V to 450 V.
Internal or external fault
(interrupted feed).
