Button
Function
Calls up the submenu in which you can set the language.
Calls up the submenu in which you can set the time zone,
the time and the date of the display.
Calls up the submenu in which you can set the country of
use and the grid standard of the photovoltaic system. If
you do not set the grid standard, the device cannot be
operated.
The display shows information on the status of the central inverter and on
possible device fault messages.
During commissioning of the central inverter, you should set the correct
time zone, the time and the date in the display.
Interfaces
Each device has interfaces for data exchange via
CAN,
|
USB and
|
Ethernet.
|
CAN
To enable communication between the central inverter and other system
components, the manufacturer uses a special CAN protocol. On the
underside of the control cabinet, there are CAN interfaces for
communication between the central inverter and
other inverters of the manufacturer,
|
the manufacturer's signal converter GridControl,
|
the manufacturer's system monitoring.
|
Please note:
Each CAN bus may be a maximum of 350 m long. The length of the
|
CAN bus is the total of the CAN cable used.
Each CAN bus requires a terminated start and a terminated end.
|
Termination is achieved by a terminating resistor (R = 120 Ω) . This
prevents signal reflections at the end of the cable. Reflections disrupt
the data signal.
The CAN interfaces of the central inverter are not terminated. The
manufacturer's Monitoring Display has terminated CAN interfaces.
