User Manual
MBUS (PLC) Communication
The MBUS (PLC) communication board loads communication signals onto power cables for
transmission.
FE Communication (Optional)
FE communication is mainly used in distributed rooftop scenarios with a small number of
inverters. The inverter can directly connect to the PC over the Ethernet to implement
monitoring networking.
If FE communication is used, set Ethernet and Management system for the SUN2000 on the
SUN2000 APP.

Figure 5-25 Communication mode for multiple SUN2000s
 The RS485 communication distance between the SUN2000 at the end of the daisy chain and the
SmartLogger cannot exceed 1000 meters.
 If multiple SUN2000s need to communicate with one another and are connected to a PC over the
SmartLogger1000, a maximum of three daisy chains can be configured.
 If multiple SUN2000s need to communicate with one another and are connected to a PC over the
SmartLogger2000, a maximum of six daisy chains can be configured.

To ensure the system response speed, it is recommended that the number of devices on each daisy
chain be less than 30.
The built-in MBUS (PLC) module in the SUN2000 does not need to be connected with cables.

FE communication is optional for the SUN2000-36KTL.
 If the SUN2000-36KTL adopts FE communications mode, it supports only RS485 and FE
communications modes, and does not support MBUS (PLC) communications mode.
 If FE communication is used, a maximum of 10 SUN2000s can be connected. In addition, the
network management software (such as the NetEco) needs to be installed on the PC for monitoring
networking.
 For operations with the SUN2000 APP, see the SUN2000 APP User Manual.
 For operations with the NMS, see the iManager NetEco 1000S User Manual (iManager NetEco
1000S V100R002C20 and later).
