WARNING
Wrong parameter settings can lead to loss of func-
tionality as well as render your system unsafe.
Modifi cations may be made only in exceptional
cases and only after having consulted with the
manufacturer and the utility company.
ACTION
To switch to programming mode, hold down key “2” for
approx. 20 seconds. Use key “1” to scroll through the various
menu items. The menu is continuous. When you reach the
end, the display automatically returns to the fi rst item.
NOTE
After the country and grid type have been set, and either
the inverter is powered down or 10 minutes have elapsed,
and a change to the country or grid type is needed, a pass
code must be obtained from KACO support. Please have
the inverter serial number available when calling to obtain
the pass code.
Explanation of the individual parameters:
Country selection
During the initial start-up, the country can be selected and
changed again without entering a code. If no entry is made for
10 minutes or the unit is switched off, the country selection
is stored. For further changes, a code is needed that can be
obtained from service.
Line under and overvoltage switch-off:
The inverter is equipped with 1-phase monitoring. If the line
voltage drops below the value set for “Minimum line voltage”,
or exeeds the value set for “Maximum line votage”, the inverter
switches off. The minimum cut-off threshold can be set in 1 V
increments.
Under and overfrequency switch-off:
The line frequency is also monitored. If the line frequency drops
below the value set in “Minimum line frequency” or exceeds
the value set in “Maximum line frequency”, the inverter
switches off. Both limit values can be set in 0.1 Hz increments.
Disconnection time:
The disconnection time value for the under and overvotage
switch off stage 1, and the disconnection time value for the
under and overfrequency switch off stage 1 can be set in 0.01
sec increments.
Starting voltage for grid-feeding:
After sunrise, the inverter will begin to feed into the grid once
the voltage has reached 410 V (display: “Start from 410 V”).
This setting enables safe operation in any solar generator
confi guration. In rare cases, it may be necessary to adjust this
starting voltage threshold. At a low generator voltage (few
modules connected in series), the starting voltage may be
reduced to ensure a safe start-up, even during unfavorable
weather conditions. At a high generator voltage, the starting
voltage may be increased to ensure that the inverter does not
switch itself on and off too often with low power. The starting
voltage can be set within a range from 370 V to 500 V in 10 V
increments.
ACTION
Use the “Settings” key to change the parameter that is
shown. The value then either increases or decreases, depen-
ding on the parameter. The values here are also continuous,
i.e. after you reach the maximum value, they return to the
minimum value.
ACTION
To leave the parameter menu, press both keys at once. Upon
leaving the menu, the settings are saved.
