Operating Instructions Powador 12.0 TL3-20.0 TL3 Page 9
3.2.4.2 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
monitoring system.
3.2.4.3 USB interface
The USB connection of the inverter is a type A socket. It is located on the connection board on the underside of the
inverter under a cover. The USB connection is specified to draw 100 mA of power. Use the USB interface for reading
out stored operating data and loading software updates using a FAT32-formatted USB stick.
3.2.4.4 S0 interface
The S0 interface transmits pulses between a pulsing counter and a tariff metering unit. It is a galvanically isolated
transistor output. It is designed according to DIN EN 62053-31:1999-04 (pulse output devices for electromechanical
and electronic meters).
The S0 interface pulse rate can be chosen in three unit intervals (500, 1,000 and 2,000 pulses/kWh).
3.2.4.5 Digital input
If Powador protect is installed as a central grid and system protection, the fail-safe disconnection of suitable
Powador 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. For information on the installation
and use see this manual, the Powador protect manual and the instructions for use of the Powador protect on the
KACO web site.
3.2.4.6 Fault signal relay/Powador-priwatt
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.
Powador-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. In Powador-priwatt mode, the potential-free contact takes care of this function.
The potential-free contact switches larger appliances (e.g. air conditioning units) on and off. This requires an external
power supply (max. 30 V DC) and an external load relay. Both can be obtained as part of the Powador-priwatt switch
from your specialist retailer.
The "Powador-priwatt" function is not active in the unit's factory default state. The option can be configured in the
Settings menu.
When the function is active, either the remaining runtime (in minutes) or the shutdown threshold (in kW) is
displayed on the start screen depending on the operating mode selected.
