KACO Gerätetechnik GmbH 13 Installation Instructions Powador 01xi
Explanation of individual parameters:
- Undervoltage break threshold:
If the grid voltage falls below a defined value the
inverter must terminate its power delivery operation and
disconnect from the grid. According to the applicable
Directive the defined value can be 1.0 to 0.8 of the grid
voltage value (184V …230V). Under standard operating
conditions the inverter shuts down at 190V and is thus
within the permissible range. Under special
circumstances your Electrical Supply Company can
request that the inverter shuts down at a different
voltage - in this case you can use the menu item
"Minimum grid voltage" to set the new break threshold.
The min. grid voltage can be adjusted in the range
between 190 V and 230 V in increments of 2 volts.
By all means ensure that the standard VDE 0126-1 is
observed.
- Overvoltage break threshold
If the grid voltage should exceed a defined value the
inverter must terminate its input operation and
disconnect from the mains. According to the directive,
this value can be 1.0 to 1.15 of the rated voltage (230V
.... 264V). Under standard operating conditions the
inverter shuts down at 264V and is thus within the
permissible range. Under special circumstances your
Utility Company may request that the inverter shuts
down at a different voltage - in this case you can use
the menu item "Maximum grid voltage" to set the new
break threshold.
- Grid frequency:
The grid frequency is also monitored. If it should fall
below a defined value the inverter must terminate its
power delivery operation and disconnect from the grid.
Both thresholds can be adjusted in increments of 0.1
Hz. The min. grid frequency range is between 49,8, –
60,0Hz, the max. frequency range is between 60,0 Hz
and 50,2,0 Hz (factory setting if 49,8, –50,2, Hz).
- Scaling Grid Voltages and Grid current:
Prior to shipment all the displayed values are checked
and adjusted in our factory. If the grid voltage shown on
the display should not correspond to the grid voltage
actually measured the value can be adjusted. If the grid
voltage shown on the display is too low you can use the
menu item "SCALING xxx +” to increase the value. If
the grid voltage shown on the display should be too
high you can use "SCALING xxx -" to reduce this value.
This scaling is available for adjusting the solar voltage,
generator current, grid voltage and grid current.
- Scaling of intermediate circuit voltage:
This parameter must only be changed by a service
technician!
- SO interface:
The SO interface is used to control a large display. Use
this parameter to adjust how many pulses per kWh are
to be transmitted. The possible settings are 500, 2000
and 1500 pulses per kWh.
After changing these parameters the inverter must be
reset to its original condition.
The inverter can now assume “normal” operation and
be left unattended. Application/Acceptance of Utility
Company
6. Applications/Acceptance by Your
Utility Company
The practices of the responsible Utility Company must
be observed for all applications and acceptances of
your PV installation. Some of the documents you will
need for application and acceptance are enclosed to
these installation instructions.
The usual setting-up procedure is as follows:
- Submittal of documents to the Utility Company
(responsibility of your solar installer)
- Installation
- Installation of power meter by the Utility Company
- Acceptance of your installation by the Utility Company
You will require the following documents:
- Application / Completion notice by the registered
installation company
- Location plan showing the estate borders and place
of installation
- Complete circuit diagram of installation and utilities
(unipolar view);
- Data sheet for independent power generating plants
(VDEW form) (responsibility of your solar installation
company);
- Description of the protection devices indicating the
type, circuit, make and function (responsibility of your
solar installation company);
- Description of the inverter / declaration of conformity
of the manufacturer;
- Information on the short-circuit resistance of circuit
components
The “Set” key is used to change the
respective parameter. Depending on the
parameter, the value increases or
decreases. The values are continuous,
i.e. if you have reached the max. value,
they will be reset to the min. value.
To do this, disconnect the inverter from
all voltage sources and reset the
jumper to its original position.
