Personnel Requirements
Only qualified and trained electrical technicians are allowed to install and operate the
SmartLogger.
Operation personnel should understand the composition and working principles of the
PV grid-tied power generating system and local regulations.
Read this document thoroughly before operations. Huawei shall not be liable for any
consequence caused by violation of the storage, transportation, installation, and operation
regulations specified in this document.
Identification Protection
The signs on the SmartLogger shell specify important information about secure
operations. Do not damage the signs.
The nameplate attached to the bottom of the SmartLogger lists the SmartLogger
parameters. Do not damage the nameplate.
Installation
Before installation, read this document carefully. Huawei shall not be liable for any
consequence caused by violation of the regulations specified in this document.
Before installing the SmartLogger, ensure that it is not connected or energized.
Install the SmartLogger in well-ventilated environments to ensure system performance.
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 communications 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 ESN 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
Has a built-in PLC CCO module through which southbound devices connect to the
SmartLogger over AC power cables.
− 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 inverter, 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.
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 a maximum of 200 devices in centralized mode and supports the access of
up to 80 inverters.
− 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 the APP 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, inverter, AC combiner box,
PLC module, and PID module, and export logs and data over the embedded WebUI.
− Allows you to manage the devices connecting to the SmartLogger and classify
alarms over the APP.
Intelligent management
− Automatically searches for and accesses Huawei inverters, AC combiner boxes,
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 inverters, AC
combiner boxes, and PID modules, and allows for RS485 address adjustment based
on ESNs to facilitate remote configuration and maintenance.
− Supports remote configuration of inverter parameters over the embedded WebUI
and synchronizes the parameters from one inverter to other inverters in batches.

2.4 Typical Networking Scenarios
Fiber+RS485/PLC Networking
A fiber network can be a ring network or 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 an AC power cable, connects to a box-type transformer over the
RS485 communications cable or Ethernet network cable, and connects to southbound devices
such as the EMI and power meter over the RS485 communications cable.
The SmartLogger is integrated with the PLC central coordinator (CCO) that can work with the
SUN2000 integrated with the PLC station (STA) to implement power line communication (PLC)
networking over power cables.
Figure 2-6 Ring fiber 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.
Multiple SmartLoggers can converge over an Ethernet switch and then connect to an NMS.
The SmartLogger connects to the Ethernet switch over optical fibers with the maximum
communications distance of 12 km in between.
LTE+RS485/PLC Networking
Figure 2-8 shows the LTE+RS485/PLC networking diagram.
In the LTE wireless networking scenario, the SmartLogger connects to the inverter over an
RS485 communications cable or an AC power cable, connects to a box-type transformer over
the RS485 communications cable or Ethernet network cable, connects to southbound devices
such as the EMI and power meter over the RS485 communications cable, connects to a
customer premises equipment (CPE) over an Ethernet electrical port, and transmits
information collected from southbound devices to an NMS in wireless mode.
The IP addresses for the SmartLogger, CPE, and monitoring devices in the box-type transformer
must be in the same network segment.
The IP address planned for the SmartLogger needs to be imported to the third-party NMS for the
NMS to proactively connect to the SmartLogger.
The IP address planned for the box-type transformer needs to be imported to the third-party NMS for
the NMS to proactively connect to the box-type transformer.
The general power input cable of the SmartACU2000 smart array controller (smart array
controller for short) needs to be prepared by the customer. Recommended cable: four-core
multi-wire (L1, L2, L3, and GND) armored; operating voltage to the ground: ≥ 600 V; and
cross sectional area of a single core: 4mm
The cable from the busbar to the knife switch needs to be prepared by the customer.
Recommended cable: three-core multi-wire (L1, L2, and L3); operating voltage to the
ground: ≥ 600 V; cross sectional area of a single core: 4 mm
The SmartLogger can be connected to the SUN2000 through an RS485 communications

cable or AC power cable. If the RS485 communications mode is used, no AC power cable
is required between the SmartLogger and the X1 terminal block in the scenario with smart
array controllers; no AC power cable is required between the SmartLogger and the MCB
in the scenario without smart array controllers.
If the SmartLogger uses the RS485 communications mode, it is recommended that at least
two RS485 signal SPDs be installed. A maximum of three RS485 signal SPDs can be
installed for each site.
Scenario With a Smart Array Controller
The smart array controller, also a communication box, is an outdoor cabinet that controls the
communication of the PV array in a PV plant. The cabinet can house components such as the
SmartLogger, RS485 signal SPD, PID module, inductor, ATB, PoE module, and PoE SPD.
The PID module and inductor are configured only in the smart array controller with the PID module
and have been installed before delivery.
The X1 terminal block (general power input and AC output) and X2 terminal block (RS485
communications port) are in the upper part on the rear of the smart array controller.
Table 2-4 lists the components required for the fiber+RS485/PLC networking mode in the
scenario with a smart array controller.
