regulations specified in this document.
Label Protection
Do not tamper with any signs on the SmartLogger enclosure because these signs contain
important information about safe operation.
Do not remove or damage the nameplate at the rear of the SmartLogger enclosure
because it contains important product information.
Installation
Ensure that the SmartLogger is not connected to a power supply and is not powered on

2 Product Overview
2.1 Overview
Function
The SmartLogger is a highly integrated device dedicated for monitoring and managing the PV
power system. It converges ports, converts protocols, collects and stores data, and centrally
monitors and maintains devices in the PV power system.
Features
The SmartLogger provides the following features:
Wide application
−Industrial-grade application, wide temperature range: –40°C to +60°C
−High altitude: applicable at an altitude of 4000 m
Various communication modes
−Bluetooth
Has a built-in Bluetooth module through which the SUN2000 APP (APP for short)
connects to the SmartLogger for parameter configuration and device maintenance.
The SmartLogger Bluetooth is named as LOG+the last eight figures of the SN of
the SmartLogger.
−Optical fiber ring switch
Provides two 100M Ethernet optical ports that support RSTP and STP to implement
fiber ring networking. If RSTP is used, fiber ring protection can be completed
within 10 seconds. If STP is used, fiber ring protection can be completed within 60
seconds.
−PLC
The SmartLogger-10-C has a built-in PLC CCO module through which
southbound devices connect to the SmartLogger over AC power cables.
The built-in PLC CCO module has the maximum voltage class of 800 VAC.
−Ethernet electrical port
Provides two 10/100M Ethernet electrical ports that can be used as southbound
ports to connect to southbound devices or used as northbound ports to connect to an
NMS.

A southbound port connects to a downstream device for collecting data and setting parameters.
Southbound devices include the SUN2000, environmental monitoring instrument (EMI), power
meter, box-type transformer, and PID module.
A northbound port connects to an upstream NMS for uploading data.
−RS485
Supports six RS485 routes and access of devices that use Modbus-RTU,
IEC103, and DL/T645.
RS485 supports the modbus-slave mode. If RS485 is set to Modbus-Slave, the
SmartLogger works in slave mode and can interwork with a third-party device,
such as a data collector and a communication manager.
Graphical data
−In addition to displaying the electricity yield and real-time monitoring information
in graphic and text format, the embedded WebUI can also display performance data
of power stations and devices in tables or curves.
−The APP displays the electricity yield and real-time monitoring information in
graphic and text format.
Centralized monitoring
−Manages up to 200 devices in centralized mode and supports the access of up to 150
SUN2000s.
−Allows you to monitor and manage the PV power system on the embedded WebUI,
for example, viewing real-time information about power stations, devices, and
faults, setting device parameters, and maintaining devices in remote mode.
−Allows you to monitor the devices in the PV power system on theAPP in real time,
such as viewing information about power stations, devices, products, and faults,
setting device parameters, and maintaining devices.
Easy maintenance
−Allows users to upgrade the firmware of the SmartLogger and export data by using
a USB flash drive.
−Allows you to upgrade the firmware of the SmartLogger, SUN2000, PLC module,
and PID module, and export logs and data over the embedded WebUI.
−Allows you to manage the devices connecting to the SmartLogger, upgrade the
firmware of these devices, exports data from these devices, and classify and query
alarms over the app.
Intelligent management
−Automatically searches for and accesses Huawei SUN2000s, PLC modules, and
PID modules. If you import a parameter configuration table, the SmartLogger can
access third-party devices that support Modbus-RTU and IEC103.
−Automatically assigns RS485 addresses to the connected Huawei SUN2000s and
PID modules, and allows for RS485 address adjustment based on ESNs to facilitate
remote configuration and maintenance.
−Supports remote configuration of SUN2000 parameters over the embedded WebUI
and synchronizes the parameters from one SUN2000 to other SUN2000s in batches.
−Automatically collects the data generated during the communication disconnection
from the SUN2000 or manually collects the data over the embedded WebUI after
the connection resumes.
Remote maintenance

−Simultaneously connects to multiple NMSs (including Huawei and third-party
NMSs) over Modbus-TCP and IEC104. Huawei NMS features centralized O&M,
big data analytics, intelligent diagnosis, and mobile O&M.
−Supports connection to a third-party NMS over File Transfer Protocol (FTP).
−Sends electricity yield and alarms to users by emails.
Grid scheduling
−The SmartLogger supports various power grid scheduling modes and therefore can
meet the requirements of power grid companies in different countries.
−Implements rapid active power control and reactive power compensation for all the
SUN2000s connecting to the SmartLogger.

The SmartLogger2000-10-C is integrated with the PLC central coordinator (CCO) that can work
with the SUN2000 integrated with the PLC station (STA) to implement PLC networking over power
cables.
The SmartLogger2000-11-C is not integrated with the PLC CCO. If PLC networking with the
SUN2000 integrated with the PLC STA is required, connect a PLC CCO to the
SmartLogger2000-11-C.

a:
If the APP fails to connect to the SmartLogger or you have forgotten the IP address, you
can press the Default key to reset the Bluetooth module or restore the IP address to the
default IP address (192.168.0.10).
To reset and restart the Bluetooth module, press and hold down the Default key for
3–10s until the BLU indicator blinks at short intervals (0.125s on and 0.125s off) and all
other indicators are off, and then release the Default key.
To restore the IP address to the default IP address, press and hold down the Default key
for more than 10s until the RUN indicator blinks at short intervals (0.125s on and
0.125s off) and all other indicators are off, and then release the Default key. The
operation is valid within 5 minutes.
2.3 Nameplate Description
A nameplate is attached at the back of the SmartLogger. The content of the nameplate
includes the SmartLogger model, rated power specifications, and certification marks. Figure
2-5 shows the nameplate of the SmartLogger2000-10-C.

2.4 Typical Networking Scenarios
Fiber+RS485/PLC Networking
A fiber network is classified into a ring network and a star network, as shown in Figure 2-6
and Figure 2-7 respectively.
In the fiber networking, the SmartLogger connects to an inverter over an RS485
communications cable or anAC power cable, connects to a box-type transformer over an
RS485 communications cable or an Ethernet network cable, and connects to southbound
devices such as the EMI and power meter over RS485 communications cables.
The SmartLogger can work with the SUN2000 equipped with the PLC STA module over an embedded
or external PLC CCO module to implement PLC networking over power cables.
Figure 2-6 Fiber ring network diagram
The SmartLogger provides two 100M Ethernet optical ports to implement ring networking.
A maximum of 16 SmartLoggers can be connected to form a fiber ring network. Each SmartLogger
can connect to southbound devices such as the inverter, EMI, and power meter.
Multiple fiber ring networks can converge over an Ethernet switch or SmartLogger and then connect
to an NMS.
