7.6 Communication
PV power stations are usually monitored from a central location.
Alongside the PV cells, the Protect PV.6x0/8x0 is a key component
of a power station, which is why various communication interfaces
are available as standard.
Available interfaces are:
Relay contacts
•
Optocouplers •
Various serial interfaces with protocols for integrating into •
higher-level monitoring systems
AEG PS offers additional components for monitoring PV power
stations, which are adapted for use with Protect PV and PV gener-
ators. This enables the client to monitor an entire PV power station
from a central location easily and reliably.
7.6.1 Communication Interface
The Protect PV 6x0/8x0 is equipped with a central communication
unit, an "MCC MultiCom interface".
This unit facilitates communication between PV inverters and
higher-level monitoring systems.
Central monitoring via the Internet, for example, is carried out us-
ing the "PV.LoG" or "Skylog" monitoring components. The connec-
tion between the inverter and the PV.LoG/Skylog data logger is es-
tablished via the Modbus protocol and has been optimally adapted
for monitoring and management purposes.
If you have any further questions, please contact AEG PS.
Another interface is the MCE Ethernet interface. It is required for
using AEG PS service remotely.
7.6.2 Serial Interfaces
Two separate potential-free serial interfaces are provided as
standard for the purpose of establishing communication connec-
tions. One interface – port X2 – is assigned the AEG PS-specific
protocol CBSER and is used locally for corresponding service
tools. The other one – port X5 – supports the Modbus protocol and
enables the Protect PV to be integrated into higher-level monitor-
ing and control systems with ease. This port can switch over from
RS-232 to RS-485.
(Default setting is RS-485)
The communication units and their connections are listed in Fig-
ure/Table 16.
The communication connections are located in the AC cabinet.
