7. Communication and Monitoring
7.1 Communication Interface
This product has a communication interface RS232, RS485 and Ethernet interface,( USB and
CAN is optional) Samil Power can offer customer USB and CAN communication interface.
Operating information like output voltage, current, frequency, fault information, etc., can be
delivered to PC or hardware storage devices or other monitoring equipment via communication
interface.
7.2 Communication
When user want to know the information of the power station and manage the entire power
system. We offer below 4 types communications.
RS232 Communication for single inverter type
RS232 is one communication interface. It transmits the data between PC and one single
SolarLake series inverters (Figure 33). For communication cable, one end is male connector;
the other end is female connector.
Figure 33 RS232 Communication Diagram
One inverter can only be communicated with one PC at the same time through RS232 port. Thus
this method is generally used for single inverter’s communication, for examples
,
software updating
and serviceman’s testing.
RS485 Communication for Several inverters
RS485 is generally for multi inverters’ communication. Up to 32 inverters could communicate
at the same time, but wire length should be
≤
1200m. System monitor SolarPower Manager
should be configured to realize one PC communicates with multi inverters at the same time. Through
PC SolarPower Manager could get real time PV plants operating data. Please see Installation
Guide of SolarPower Manager for more information. Connect the system as blow (Figure34),
user can easily monitoring the PV power station.
