5.9 Parameter programming
Various operating mode parameters can be set in the
parameter 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. Insert
disconnecting time for fast and slow undervoltage.
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.
Insert disconnecting time for fast and slow overvoltage.
Under and overfrequency switch-off:
The line frequency is also monitored. If the line fre-
quency 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. Insert disconnecting
time for fast and slow grid frequency.
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 unfavorable weather condi-
tions. 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.
Ground fault monitoring:
One pole of the PV generator is grounded in the unit
using a fuse. Ground fault monitoring is triggered in the
event of an ground fault in the generator. This prevents
possible damage to the modules.
Power limitation:
The gradation is in 10 W increments and is limited to 50
% of the initial value. → Set power limitation
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.
