Service technicians can use this menu item for changing additional
MSD parameters.
3.4 Cooling
The internal temperature control system prevents excessive oper-
ating temperatures. When the internal temperature is too high, the
inverter adjusts the power consumption from the PV generators to
reduce the heat dissipation and operating temperature.
The inverter is convection cooled via fins on the front and rear side.
A maintenance-free fan circulates the heat within the closed housing
evenly over the entire surface of the housing.
3.5 Grid monitoring
The inverter constantly monitors the mains grid parameters while
feeding the grid. If the grid deviates from the legally prescribed
specifications then the inverter automatically switches off. When the
grid conforms to the legally prescribed specifications then the
inverter automatically switches on again.
3.6 Data communication
The device has the following communication interfaces:
n
1x RJ45 socket (Ethernet for TCP/IP network) for communica-
tion, e. g. with a central data server
n
2x RJ45 sockets (RS485 bus) for communication with external
devices, e. g. a data logger
n
1x RJ10 socket (Modbus RTU) for communication e. g. with an
external energy counter
3.6.1 Data
The inverter can transmit a wide range of data to other devices.
Some of this data is shown on the display and certain data is stored
in the internal memory (EEPROM) as described below.
n
Voltage and current of the PV generator
n
Power and current fed into the grid
n
Voltage and frequency of the power grid
n
Energy yields on a daily, monthly and annual basis
n
Error conditions, notes
n
Version information
n
Event messages with date
n
Energy yields on a daily, monthly and annual basis
The storage resolution of the energy yield data is as follows:
