The SmartLogger monitors and manages PV power systems. It converges all ports, converts protocols, collects and stores data, and centrally monitors and maintains the devices in PV power systems.

Network Application

The SmartLogger applies to PV power systems. It supports the following:

  • Local operations on the SmartLogger using the mobile phone app through the built-in WLAN
  • RS485 networking, which enables the SmartLogger to connect to:
    • Huawei devices such as solar inverters and PID modules
    • Third-party solar inverters, environment monitoring instruments (EMIs), transformer stations, and power meters that use the Modbus-RTU protocol
    • Power meters that use the DL/T645 protocol
    • Devices that use the IEC103 protocol
  • MBUS networking, which enables the SmartLogger to connect to Huawei solar inverters and PID-PVBOXs that support MBUS communication
  • Connection to management systems:
    • Connects to a management system that uses the Modbus TCP protocol over a wired or wireless network.
    • Connects to a management system that uses the IEC104 protocol in the LAN over a wired network.

The SmartLogger cannot be connected to a management system that uses the IEC104 protocol over a 4G/3G/2G or LTE dedicated network.

Typical Networking Scenarios

  • The SmartLogger supports the following wired networks: fiber ring network, fiber star network, and Ethernet star network.
Figure 2-3 Fiber ring network
  • A maximum of 15 SmartLoggers can be connected to form a fiber ring network. Each SmartLogger can connect to devices such as solar inverters, EMIs, and power meters.
  • Multiple fiber ring networks can be connected to the management system through an Ethernet switch.
Figure 2-4 Fiber or Ethernet star network
  • Multiple SmartLoggers can be connected to the management system through an Ethernet switch.
  • When the SmartLogger connects to an Ethernet switch over optical fibers, the maximum communication distance is 12 km (with the 100M optical module) or 10 km (with the 1000M optical module). The maximum communication distance is 100 m when an Ethernet cable is used for connection.
  • The SmartLogger supports the following wireless networks: 4G/3G/2G networking and LTE dedicated networking.
Figure 2-5 4G networking
Figure 2-6 LTE dedicated networking
  • The WAN port of the SmartLogger connects to the customer-premises equipment (CPE) through the power over Ethernet (PoE) module and PoE SPD.
  • The IP addresses of the SmartLogger and CPE must be on the same network segment.
