feed-in mode (green LED lit).
DAMAGE POSSIBLE
Dirty or blocked fans mean that the
inverter is not adequately cooled.
Insufficient cooling of the inverter
may result in output reduction or
the failure of the system.
Always mount inverters in such a
way that falling parts cannot fall
into the inverter through the ven-
tilation grill or mount the optional
fan cover.
