 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:

Description
Page  Operating Instructions for Powador .-. TL_EN
ENEN 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”
function 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 unit’s delivery state. The option can be congured in the Settings menu.
.. Interfaces
RS interface
Use this monitoring option if you cannot check the functioning of the system on-site on a regular basis, e.g. if your
place of residence is located a great distance from the system. To connect the RS interface, contact your author-
ised electrician.
For monitoring your PV system using the RS interface, KACO new energy GmbH oers monitoring devices:
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 monitoring a system comprising several inverters, we recommend you use an external data logging and moni-
toring system.
USB interface
The USB connection of the inverter is a type A socket. You will nd the USB connection on the connection circuit
board in the upper area on the inside of the door. The USB connection 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.
S interface
The S interface transmits pulses between a pulsing counter and a tari metering unit. It is a galvanically isolated
transistor output. It is designed according to DIN EN -:- (pulse output devices for electromechanical
and electronic meters).
NOTE
The S interface sends a specic number of pulses per kilowatt-hour output.
The number of pulses per kilowatt-hour output that can be sent by the S interface depends on the
maximum feed-in power of the inverter and can be set in the menu.
30.0-36.0 TL3 500, 1,000 or 2,000 pulses/kWh.
39.0-60.0 TL3 500 or 1000 pulses/kWh
72.0 TL3 500 pulses/kWh
“Inverter O" input
If Powador protect is installed as a central grid and system protection, the fail-safe disconnection of suitable KACO
inverters from the public grid can be initiated by a digital signal instead of tie circuit-breakers. This requires the
inverters in the photovoltaic system to be connected to the Powador protect. Information on installation and use
can be found in this manual, in the Powador protect manual and in the instructions for use of the Powador protect
on the KACO web site.
