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 “priwatt” mode, the potential-free contact takes care of this function.
The potential-free contact switches larger consumers (e.g. air conditioning units) on and off . This requires an exter-
nal power supply (max. 30 V DC) and an external load relay. Both can be obtained as part of the priwatt-switch from
your specialist retailer.
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 confi gured in the Settings menu.
3.2.3 Interfaces
You confi 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 monitoring a system comprising several inverters, we recommend you use an external data logging and moni-
toring system.
RS485 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 RS485 interface, contact your author-
ised electrician.
For monitoring your PV system using the RS485 interface, KACO new energy GmbH off ers monitoring devices:
Only the RS485 interface continues to transmit data if the inverter in an inverter group fails.
USB interface
The USB connection of the inverter is a type A socket. It is located on the connection circuit board behind the cover
for the connection area. The USB connection is specifi ed 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.
"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 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 new energy website.
S0 interface (optional)
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).
The optional interface module is available from the service department of KACO new energy.
