Third-party solar inverters, environment monitoring instruments (EMIs),
Smart Transformer Stations (STSs), and power meters that use the
Modbus-RTU protocol
– Power meters that use the DL/T645 protocol
– Devices that use the IEC103 protocol
● Ethernet networking, which connects to the solar inverter, Smart Power
Control System (Smart PCS), Smart String Energy Storage System (ESS),
MBUS CCO, and STS.
● 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 northbound wired networks: ber
ring network, ber star network, and Ethernet star network.
