DTU-Pro-S 4G LTE Communication Module Hoymiles

The DTU-Pro-S (4G version) communication module is a data transmission device designed for photovoltaic systems with Hoymiles microinverters. It collects information from microinverters via Sub-1G connectivity and transmits it to the S-Miles Cloud platform, providing remote access to data and alarms as well as the ability for remote operation and updates.

Manufacturer: Hoymiles Power Electronics Inc. is a specialist in monitoring solutions and photovoltaic microinverters. The company offers the S-Miles Cloud platform and configuration tools (S-Miles Toolkit) enabling local and remote configuration and management of PV systems.
