• Note that only professionals may install or replace DTU. • Do not try to repair the DTU without approval from Hoymiles. If the DTU is damaged, send the DTU back to your installer for repairing/replacement. Disassembling the DTU without approval from Hoymiles will invalidate the remaining warranty period.
The DTU The DTU is a key component in the Hoymiles microinverter system. It works as the communication gateway between the Hoymiles microinverters and the S-Miles Cloud (Hoymiles Monitoring Platform). The DTU communicates wirelessly with the microinverters via 2.4 GHz Proprietary RF (Nordic), and collects the operation data of the system.
Refer to the microinverter’s Manual or Quick Installation Guide for detailed installation steps. 2) Locate the DTU The maximum communication distance of Hoymiles DTU is 150 m in open space. The walls, roofs, or other obstacles in between will affect the signal and reduce the communication distance in actual installations.
