DTU Installation Procedure
(1) Install the PV Modules and microinverters
Please refer to the Microinverter
’
s Manual or Quick Installation Guide for the detail installation steps.
(2) Locate the DTU
The maximum communication distance of Hoymiles DTU is 150m in open space. The walls, roofs, or
other obstacles in between will affect the signal and reduce the communication distance in the real
installation.
The range of signal reduction for possible obstacles at the site has been shown below:
Material Relative signal range reductions
Wood/Glass 0-10%
Stone/Pressed cardboard 10%-40%
Reinforced concrete (reduction increases with the
amount of reinforcement)
10%-90%
Metal Up to 100%
Therefore, the DTU shall be placed as close to the microinverters as possible at the site to ensure
good communication between DTU and microinverters.
