 Description
. Mode of Operation
The inverter converts the DC voltage generated by the PV modules into AC voltage and feeds it into the grid. The
starting procedure begins when there is sucient sunlight and a specic minimum voltage is present in the inverter.
The feed-in process begins once the PV generator has passed the insulation test and the grid parameters are within
the requirements imposed by the grid operator for a specic monitoring time. If, as it gets dark, the voltage drops
below the minimum voltage value, feed-in operation ends and the inverter switches o.

.. Electrical functions
A potential-free relay contact is integrated in the inverter. Use this contact for one of the following functions:
Fault signal relay
The potential-free relay contact closes as soon as there is a fault during operation. You use this function, for example,
to signal a fault visually or acoustically.
Priwatt
The energy that is provided by the PV system can be put to use directly by the appliances that are connected in your
home.
The potential-free contact can switch larger appliances (e.g. air conditioning units) on and o with the Priwatt func-
tion activated. This requires an external power supply and an external load relay.
When the function is active, either the remaining runtime (in hours and minutes) or the shutdown threshold (in kW)
is displayed on the start screen depending on the operating mode selected. The Priwatt function is not active in the
factory default setting. The option can be congured in the Settings menu.
.. Interfaces
You congure the interfaces and the web server in the Settings menu.
The inverter has the following interfaces for communication and remote monitoring:
Ethernet interface
Monitoring can occur directly on the unit using the integrated Ethernet interface. A local web server is installed in
the unit for this purpose. For the monitoring of a system consisting of multiple inverters, we recommend the utiliza-
tion of the Powador-web portal on our homepage.
RS interface
In addition to the monitoring via the Ethernet interface, the monitoring can be executed via the RS interface.
USB interface
The USB connection of the inverter is a type A socket. It is located on the connection board in the door. The USB con-
nection is specied to draw mA of power. Use the USB interface to read out stored operating data and to load
software updates using a FAT-formatted USB stick.
“Inverter O” input
If Powador-protect is installed as the central grid and system protection, the fail-safe shutdown of suitable Powador
or blueplanet inverters from the public grid can be initiated by a digital signal instead of external circuit-breakers.
This requires the inverters in the photovoltaic system to be connected to the Powador-protect.
If a Powador-protect is used for fast shutdown, it must be used as grid protection. The RS interface is not
required for this.
For information on the installation and use see this manual, the Powador protect operating instructions and the
instructions for use of the Powador protect on the KACO new energy website.

Lifting and installing the unit
ඣWall holder mounted.
. Use the lateral openings for lifting or insert the transport device into the lateral slots and lift the unit at the
designated positions (see Figure  on page ).
. Hang the inverter on the wall holder using the suspension brackets on the back of the housing.
NOTE: Keep in mind that the lower marking on the housing must protrude over the upper outer contour of the
wall holder. (See Figure  on page ). Ensure that the upper marking is ush with the upper edge of the outer
contour when lowering the unit. The outer contour of the wall holder must be ush with the outer contour of the
housing.
. Insert the provided screw into the bracket on the wall holder and fasten the inverter to secure against dis-
placement.
Alternatively: At this point, the screw mentioned at step  can be replaced by a special screw as anti-theft protec-
tion.
» Installation of the inverter is complete. Proceed with the electrical installation.
CAUTION
Property damage as a result of condensation
During pre-assembly of the inverters, moisture can penetrate into the interior via the DC plug connec-
tors and the dust-protected threaded connections. The resulting condensate can cause damage to the
unit during installation and start-up.
ඣKeep the unit closed during pre-assembly and do not open the connection area until you perform
installation.
› Use sealing covers to seal o all plug connectors and threaded connections.
› Prior to installation, check the inner area for condensation and if necessary, allow it to dry suciently
before installation.
› Immediately remove any moisture from the housing.
