VariantsWLite S / Lite S / Pro S
ConnectivityWi-Fi / 4G / Ethernet
Capacityup to 99 microinv.
MonitoringS-Miles Cloud

Monitoring gateways (data transmitters) for Hoymiles microinverters. They collect module-level data and alarms over a Sub-1G wireless link and send them to the S-Miles Cloud, where you can view system performance and run remote configuration and updates. DTU-WLite S supports up to 4 panels, DTU-Lite S and DTU-Pro S up to 99, and the Pro S variant adds Ethernet and 4G connectivity, RS485 ports and zero-export control.

Variants

Three models and selection.

Choose the model based on your microinstallation size and connectivity needs. WLite S suits a single microinverter, Lite S and Pro S handle up to 99 panels, and Pro S adds Ethernet, 4G and ports for peripheral devices.
