overvoltage, severe weather, fi re)
– Insuffi cient ventilation of the unit
– Failure to observe the relevant safety regulations
– Transport damage.
All warranty claims must be handled at the premises of KACO

in its original or equivalent packaging. The costs for these
services cannot be borne by KACO new energy GmbH.
KACO new energy GmbH will only perform warranty services
if the defective unit is returned to KACO new energy GmbH
together with a copy of the invoice which was issued to the
user by the dealer. The name plate on the unit must be fully
legible. If these requirements are not fulfi lled, KACO new

4 Operation
The grid feed process begins in the morning when suffi cient
light is available, and, therefore, when a certain minimum
voltage is present at the inverter. The inverter enables grid
feed after a country-specifi c start-up time (see Installation
Manual, section 4, “Technical Data”).
If, as nightfall approaches, the voltage drops below the
minimum voltage, the grid feed mode ends and the inverter
switches off.

4.2 LED displays
During normal operation, the photovoltaic modules generate
voltage as soon as the insolation is suffi cient. If this voltage is
present in the inverter at a certain level for a certain time, the
inverter begins to feed into the grid.
The inverter is equipped with three LEDs, which give informa-
tion about the various operating statuses as follows.
