3.2.2 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 off 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 configured in the Settings menu.
3.2.3 Interfaces
You configure 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 utilization of the Powador-web
portal on our homepage.
RS485 interface
In addition to the monitoring via the Ethernet interface, the monitoring can be executed via the RS485 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 specified to draw 100 mA of power. Use the USB interface to read out stored operating data and to load
software updates using a FAT32-formatted USB stick.
“Inverter Off” input
If Powador protect is installed as a central grid and system protection, the fail-safe disconnection of suitable Pow-
ador or blueplanet inverters from the public grid can be initiated by a digital signal instead of external interface
switches. 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 RS485 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.
