The backlight of the display is switched on by pressing any button. The operating states of
the inverter are shown as follows:

Cooling
The inverter may heat up during operation. This is a normal operating characteristic.
When the internal temperature rises above a certain value, an internal temperature control-
ler regulates the power consumption from the PV generator. The operating temperature
decreases when power consumption is lower.
A fan disperses the waste heat inside the closed case evenly onto the case surface.
Cooling fins allow the heat to dissipate to the surrounding.

Grid monitoring
The grid monitoring in the device permanently monitors the grid parameters of the public
grid. If the grid monitoring detects a deviation of the grid parameters from the statutory re-
quirements, the device switches off automatically. When the public grid meets the statutory
requirements again, the device switches on again automatically.

Data
3.7.1 Data communication
The device has the following communication interfaces:
•
"LAN" connection (Ethernet for TCP/IP network) for the communication with a central
data server
•
"COM2" connection (Modbus RTU) for the communication with e.g. an external energy
meter
•
"COM1" connection (RS485 bus) for the communication with external devices, e.g. with
a data logger (in the case of StecaGrid ####_2: two connections)
For data analysis purposes, the inverter can provide a wide range of data via the RS485
and LAN interfaces (e.g. data logger). The RS485 bus also allows the connection to other
inverters.
