Hoymiles gateway DTU-Pro and DTU-Pro-S Models are data transfer units that collect information and data from PV microinverters using a Sub-1G wireless solution and sends them to S-Miles Cloud, Hoymiles’ Monitoring Platform. 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.
