Fronius IG 15 - Manual (Page 24)

Depending on the operating status, the LED assumes different colours
(1) LED lights up green:
- a green light starts as soon as the FRONIUS IG unit has completed
the startup phase, it stays green as long as the operation of feeding
power into the network continues
- it indicates faultless operation of the photovoltaic equipment
(2) LED flashes green:
- as long as the photovoltaic equipment is operating without fault
- and an additional message is displayed on the screen
Note! A message appears for example if there is an insulation
fault, which however does not affect the function of the FRONIUS
IG. However for safety reasons we recommend that the insulation
fault is remedied as soon as possible.
Depending on the country setup, the inverter can also disconnect
from the public grid when there is an insulation error and stop
feeding energy into the grid.
The FRONIUS IG with display shows a status message. A message is
displayed in the FRONIUS IG.access software for the FRONIUS IG wit-
hout display.
If a message (e.g. „502“, Section „Status diagnosis and remedy) is shown,
rectify the relevant status and acknowledge this by pressing the „Enter“
button.
(3) LED lights up orange:
- The FRONUS IG unit will enter the automatic startup-phase, as soon
as after sunrise the photovoltaic modules yield sufficient power output
