Hello everyone, today I will introduce to you the networking introduction of Smartlogger3000.
Function
The SmartLogger is a dedicated device for monitoring and managing the PV power system. It aggregates ports, converts protocols, aggregates data, stores data, monitors devices in a centralized manner, and maintains devices in the PV power system.
Networking Application
The SmartLogger applies to PV power systems.
Supports local operations on the SmartLogger through the built-in Wi-Fi.
Supports RS485 networking.
- Connects to Huawei inverters and PID devices.
- Connects to third-party inverters, EMIs, box-type transformer stations, and electric meters that comply with the standard Modbus-RTU protocol.
- Connects to a power meter that uses the DL/T645 protocol.
- Connects to devices that comply with the standard IEC103 protocol.
MBUS networking is supported to connect Huawei inverters and PID-PVBOXs that support MBUS communication.
Supports connection to the management system:
- Connects to the management system that uses the Modbus TCP protocol over a wired or wireless network.
- Connects to the management system that uses the IEC104 protocol on the LAN through a wired network. Note:
The SmartLogger cannot connect to the management system that complies with the IEC104 protocol through a 4G/3G/2G network or an LTE dedicated network.
Typical Networking Scenarios
The SmartLogger supports the following wired networks: fiber ring topology, fiber star topology, and Ethernet star topology.
Figure 1 Fiber ring topology
Note:
A maximum of 15 SmartLoggers can be connected to a fiber ring network consisting of SmartLoggers. Each SmartLogger can be connected to devices such as inverters, EMIs, and electric meters.
Multiple optical ring networks can be converged by using Ethernet switches and then connected to the management system.
Figure 2 Optical fiber or Ethernet star topology
Note:
Multiple SmartLoggers can be converged through Ethernet switches and then connected to the management system.
When the SmartLogger is connected to an Ethernet switch through optical fibers, the maximum communication distance is 12 km (with 100 Mbit/s optical modules configured) or 10 km (with 1000 Mbit/s optical modules configured). When the SmartLogger is connected through Ethernet cables, the maximum communication distance is 100 m.
The SmartLogger supports 4G/3G/2G networks and LTE dedicated networks.

Figure 4 LTE private network networking
Note:
The WAN port of the SmartLogger connects to the customer-premises equipment (CPE) through the PoE module and PoE SPD.
The IP address of the SmartLogger and the IP address of the CPE must be in the same network segment.
