5.9 Parameter programming
Various operating mode parameters can be set in the param-
eter mode menu of blueplanet units.
! WARNING
Wrong parameter settings can lead to loss of
functionality as well as render your system
unsafe.
Modifications 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 first 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 undervoltage switch-off:
The inverter is equipped with 1-phase monitoring. If the line
voltage drops below the value set for “Minimum line voltage”,
the inverter switches off. The minimum cut-off threshold can
be set in 1 V increments.
Line overvoltage switch-off:
If the line voltage exceeds the value set for “Maximum line
voltage”, the inverter switches off. The 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.
Starting voltage for grid-feeding:
After sunrise, the inverter will begin to feed into the grid once
the voltage has reached 125 V / 200 V (display: “Start from 125
V / 200 V”). This setting enables safe operation in any solar
generator configuration. 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 unfa-
vorable 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 125 V to 150 V
or 200 V to 225 V in 5 V increments.
ACTION
Use the “Settings” key to change the parameter that
is shown. The value then either increases or decreases,
depending 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.
