Hoymiles HMS-1600-4T & DTU Wlite S SET

The Hoymiles HMS-1600-4T & DTU WLite S SET combines the HMS-1600-4T 4-in-1 single-phase microinverter with the DTU-WLite-S data transfer unit for residential and small commercial PV systems. The HMS-1600-4T has a rated output power of 1600 VA and can connect up to four PV modules, with four independent MPPTs and one input per MPPT. It supports a maximum input voltage of 65 V, an MPPT voltage range of 16–60 V and a maximum input current of 4 × 14 A, making it suitable for commonly used PV modules in the approximately 320–540 W+ range. The 4-in-1 architecture helps reduce equipment and installation complexity. The DTU-WLite-S communicates with the microinverter through Sub-1G wireless technology, with a communication distance of up to 400 m in open space, and supports monitoring data from up to four solar panels. It then uses Wi-Fi to transfer data to S-Miles Cloud for module-level monitoring, alarm information and remote system management.
