1.1 Read this First
This manual includes important instructions for installing and maintaining the Aptos Data
Transfer Unit (MACTM DTU).
1.2 Safety Instructions
Note that only professionals can install or replace DTU.
Do not try to repair DTU without approval from Aptos. If DTU is damaged, please return
to your installer for repairing/replacing. Disassembling DTU without approval from Aptos will
invalidate remaining of the warranty period.
Please read all instructions, warnings, and technical specifications carefully.
Do not use Aptos products in ways unspecified by manufacturer. Doing so may result
death/injury to persons or damage to equipment.
1.3 User
This manual is only for professional installation and maintenance personnel to use.
1.4 Support and Contact Information

2. Aptos Solar Technology Microinverter System
2.1 Microinverter
The Microinverter converts the DC output of PV modules into grid-compliant AC power. It
sends the output information of PV modules and the operation data of the microinverters to
the DTU, which is the hardware basis of the module-level monitoring. With conversion
efficiency up to 96.7%and MPPT efficiency up to 99.9%, Aptos microinverters rank in
the first class of the world’s microinverter industry.
2.2 DTU
The DTU is the key component in Aptos microinverter system. It works as the
communication gateway, which operates between the Aptos microinverters and the
Aptos Monitoring Server. The DTU communicates with the microinverter wirelessly via
2.4GHz Proprietary RF (Nordic), collecting the operation data of the system. Meanwhile, the
DTU connects to the Internet via router and communicates with Aptos Monitoring Server. The
microinverter system operation data will be uploaded to Aptos Monitoring Server via DTU.
2.3 Aptos Monitoring Server
The Aptos Monitoring Server collects the operation data and status of the microinverters in
the system and provides the module-level monitoring for the users and maintenance staff.

b. Export Control Type.
Type 1: Zero Export: to limit the exporting power to zero so that it can prevent the
generated power feed back to the grid.
Type 2: Export Limit: to limit the exporting power within a certain value.
Type 3: Production and Consumption Monitoring: enable to measure the PV
generating under a high accuracy.

Note: Please refer to “Aptos Export Management Technical Note” for more details.
3.3 Remote Active Power Control (RS485 port)
Some countries require generating plants to be equipped with a logic interface (input port) in
order to cease output active power or limit active power to a regulating level. This logic
input can be RS485 port, Ethernet port, etc. MACTM DTU provide RTU Modbus protocol
over RS485 port for this remote active power control. For more information, please refer to
“Modbus implementation Technical Note”.
3.4 DRM Port

3.5 Local Install Assistant
Local Install Assistant is a new function integrated with MACTM DTU. Please download
the Installer App (for installer/distributor use only) first.
MACTM DTU has improved from the previous generation of DTU products. New
functions allow installer to:
a. One step to complete the WiFi configuration;
b. Station overall Inverters status indication allows the installer to see how many MI under
this DTU is working properly (and the details for each MI) and how many is abnormal (and
the details for each MI) with one glance of eyes;
c. Add the Connection status, which will display the signal strength between each MI with
connected DTU, so that installer can adjust the DTU installation location accordingly. This
function will simplify the DTU installation, and avoid a second visit by the installler due to a
poor connection between DTU and certain MI.
Note: Please refer to “Aptos Local Install Assistant Technical Note” for more details.

4. DTU Installation
4.1 System Capacity
The MACTM DTU is capable of monitoring up to 99 panels. If the communication between
the DTU and microinverter caused by the installation conditions, the number of PV modules
that the DTU can monitor may be reduced.
Note: Max. monitoring quantity is for open space, installation condition meets the
requirement from both DTU and Microinverter manual, and the distance between
Microinverter and DTU needs to be within the required range.
4.2 Basic Conditions Required
Before installing the DTU, ensure that the site meets the following requirements:
Standard 220 VAC power outlet.
Stable broadband internet connection.
Router with Ethernet port.
The environmental requirements for DTU installation:
Away from dust, liquid, acidic, or corrosive gas.
The temperature should be between -20ºC and 55ºC.
If you plan to install the DTU on the wall, please prepared two #8 (4.166mm diameter) screws
and a screwdriver in advance.
