2.The monitoring system of Hoymiles
The DTU is the key component in Hoymiles monitoring system. It is the relay station of
the monitoring system, which operates between the Hoymiles microinverters and the
Hoymiles Monitoring Server. The DTU communicates with the microinverters in the system
via 2.4G RF wireless to collect the data and status of the microinverters in the system. At the
same time, DTU connects to the Internet through WIFI,which realizes the information
exchange with the Hoymiles cloud monitoring service platform and sends all the running
data of microinverters and status of the system to the Hoymiles cloud monitoring server. It
receives the control commands from the cloud monitoring server and sends the data to the
microinverters in the system to achieve remote operation and maintenance.

Other Elements in the Hoymiles Microinverter System
The Microinverter: It converts the DC output of solar modules into grid-compliant AC power.
It sends the output electrical information of PV panels and the operation data of the
microinverters to the DTU, which is the hardware basis of the panel-level monitoring. With
efficiency up to 96.7% and MPPT efficiency up to 99.9%, Hoymiles microinverters rank in the
first level around the world in 2015.
The Hoymiles Monitoring Server: It collects the operation data and status of the
microinverters in the system, and provides the panel-level monitoring for the users and
maintenance staffs t o achieve remote operation and maintenance, which can improve
operational and maintenance efficiency.
3. DTU Installation Operation
3.1 Install The DTU
1.Plug the DTU connection adapter into the wall socket (the wall socket should be more than
1 meter above the ground).

7
2.Or plug the DTU into the power adapter and plug it into the cable outlet. Place the socket
on the table (when the table is placed, the table surface should be more than 1 meter
above the ground).
Note: The table should not be metal or concrete structure (to prevent the effects on 2.4G RF
signal).
3.The DTU is placed as far as 90 degrees vertically upwards.
4.The distance between the DTU and the router should be as close as possible.
3.2 WIFI Configuration Process
Connect the wireless name of DTUW- via computer or mobile phone, and then open the
browser and enter 10.10.100.254 to open the wifi configuration page. The username and
password are ‘admin’ by default. After entering, click the wifi parameter menu on the left
menu bar to enter the wifi parameter configuration. Then click the search button in the lower
right corner, select the wifi name to be connected to the DTU and enter the password, then
click Save and click Restart next.
Note: Non-professionals should not modify other parameters.

3.3 Boot Process
When the DTU starts to work, the red, green and blue lights are on for one second, then
the red light is on. The green light flashes to indicate that the search is slightly reversed and
connected to WIFI. The red and green lights flash alternately to indicate that the server is
connected and the WIFI is searched. After the search, the green light stops flashing and
turns solid.

FCC Statement
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause undesired
operation.
NOTE: This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates uses and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver
is connected.
- Consult the dealer or an experienced radio/TV technician for help.
WARNING: Any changes or modifications not expressly approved by the party responsible
for compliance could void the user's authority to operate this equipment.
The device must not be co-located or operating in conjunction with any other antenna or
transmitter.

IC Statement
This device complies with Industry Canada licence-exempt RSS standard(s). Operation
is subject to the following two conditions: (1) this device may not cause interference, and (2)
this device must accept any interference, including interference that may cause undesired
operation of the device.
Under Industry Canada regulations, this radio transmitter may only operate using an
antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry
Canada. To reduce potential radio interference to other users, the antenna type and its gain
should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more
than that necessary for successful
communication.
Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut
fonctionner avec une antenne d'un type et d'un gain maximal (ou inf érieur) approuvé pour
l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage
radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son
gain de sorte que la puissance isotrope rayonn ée équivalente (p.i.r.e.) ne dépasse pas
l'intensité nécessaire à l'établissement d'une communication satisfaisante.
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils
radio exempts de licence. L'exploitation est autoris é e aux deux conditions suivantes : (1)
l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout
brouillage radioélectrique subi,même si le brouillage est susceptible d'en compromettre le
fonctionnement.
The device must not be co-located or operating in conjunction with any other antenna or
Transmitter.
To comply with FCC’ s and Industry Canada’s RF radiation exposure limits for general
population/uncontrolled exposure, this device must be installed to provide a separation
distance of at least 20cm from all persons.
