Hoymiles gateway DTU-Pro-S is a data transfer unit that collects information and data from PV microinverters using a Sub-1G wireless solution and sends them to S-Miles Cloud, Hoymiles’ Monitoring Platform, using different communication options such as Ethernet, Wi-Fi or 4G. Supporting remote O&M and monitoring, users can easily read module-level data and alarms, and access remote operation and maintenance commands of the PV system at any time, from anywhere on S-Miles Cloud.
