- Page 4 The DTU The DTU is a key component in the Hoymiles microinverter system. It works as the communication gateway between the Hoymiles microinverters and the S-Miles Cloud (Hoymiles Monitoring Platform). The DTU communicates wirelessly with the microinverters via 2.4 GHz Proprietary RF (Nordic), and collects the operation data of the system. Meanwhile, the DTU connects to the Internet via the router and communicates with the S-Miles Cloud. The microinverter system operation data will be uploaded to the S-Miles Cloud via DTU. The S-Miles Cloud (Hoymiles Monitoring Platform) It collects the operation data and status of the microinverters in the system and provides module-level monitoring for users and maintenance staff.
