hoymiles DTU-Plus-S-C Data Transfer Unit Module User Manual

Description

The DTU-Plus-S-C serves to collect and transmit data from micro-inverters in the Hoymiles microinverter system. It uses Ethernet and 4G technology to communicate with the monitoring platform S-Miles Cloud. It is also equipped with industrial communication interfaces that support various communication schemes for power plants.

The DTU-Plus-S-C can reduce O&M efforts signi icantly by providing module- level monitoring data and fault alarms in real-time, either on-site or virtually, and enabling remote O&M through the S-Miles Cloud or third-party platforms.
