The SmartLogger is dedicated for monitoring and managing the PV power generating system.
It converges all ports, converts protocols, collects and stores data, and centrally monitors and
maintains the PV power generating system.
Networking
The SmartLogger applies to a PV system.
It can monitor Huawei inverters, PID, and other devices.
It supports third-party devices such as inverters, environment monitoring instruments,
box-type transformers, and smart meters that use the standard Modbus protocol or
provide RS485 ports.
It can simultaneously connect to the Huawei and third-party network management
systems by using the Modbus-TCP and IEC104 protocols.
It can connect to a multi-functional power meter over DLT645.
The SmartLogger networking is shown in Figure 2-1.

Features
The SmartLogger has the following features:
Central monitoring
−Centrally monitors a maximum of 80 devices.
−Allows users to view information about the power station, devices, products, and
alarms, set parameters, and maintain devices on the liquid crystal display (LCD).
−Allows users to monitor and manage the PV power generating system on the
embedded WebUI, for example, viewing real-time information about the power
station, devices, and faults, and setting device parameters in remote mode.
Graphical data
−Displays energy yields and real-time monitoring information on the LCD in
graphics and texts.
−Displays energy yields, real-time monitoring information, and performance data of
the power station and devices on the embedded WebUI in tables and curves.
Convenient maintenance
−Allows users to upgrade the firmware of the SmartLogger and inverters and export
data by using a USB flash drive.
−Allows users to upgrade the firmware of the SmartLogger or inverters and export
logs over the embedded WebUI.
Grid dispatching

Supports power grid dispatching: active power reduction and reactive power
compensation.
Intelligent management
−Automatically scans and identifies Huawei inverters and supports protocol
conversion for third-party devices
−Supports access from third-party devices that use the standard Modbus-RTU
protocol.
−Automatically assigns RS485 addresses to the connected inverters and allows for
adjusting RS485 addresses based on device sequence numbers to facilitate remote
configuration and maintenance.
−Supports remote setting of inverter parameters and synchronizes the parameters of
one inverter to other inverters in batches.
Remote maintenance
−Supports connection to both Huawei NMS and a third-party NMS using
Modbus-TCP and IEC104 protocol to remotely manage all devices.
−Allows users to access a third-party NMS over the File Transfer Protocol (FTP).
−Sends energy yield and fault information to users by emails.
