General about Microinverter System
The Microinverter
It converts the DC output of solar panels into grid-compliant AC power. It
sends the output information of solar panels and the operation data of the
microinverters to the WiFi Stick (DTU), which is the hardware basis of
panel-level monitoring.
The WiFi Stick (DTU)
The DTU is a key component in the 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. Meanwhile, the DTU connects to
the Internet via the router and communicates with the S-Miles Cloud
(Hoymiles Monitoring Platform). The microinverter system operation data
will be uploaded to the S-Miles Cloud (Hoymiles Monitoring Platform) via
DTU.
The S-Miles Cloud (Hoymiles Monitoring Platform)
It collects the operation data and status of the microinverters in the system
and provides panel-level monitoring for users.
Installation
System Capacity
The DTU can monitor up to two micro-inverters with a maximum of four
solar modules. If the communication between the DTU and the
microinverters suffers interference caused by installation conditions, the
number of solar panels that the DTU can monitor may be reduced.
Basic Conditions Required
Before installing the DTU, make sure that the site meets the following
requirements:
• Install the DTU close to the router.
• Stable Internet connection.
• The straight distance between the DTU and the microinverter must
be less than 10 meters.
• The location should be 1.0 meter above the ground and 0.8 meters
away from corners.
Environmental requirements for DTU installation:
• Away from dust, liquid, acids, or corrosive gas.
• The temperature should be between -20ºC and 55ºC.
