5.  Installation Planning and Preparation

5.1  Pre-installation

5.1.1  System Capacity

The DTU-Pro-S is capable of monitoring up to 99 PV modules. If the communication between the DTU 
and microinverter is affected by the installation conditions, the number of PV modules that the DTU 
can monitor may be reduced.

Note: The maximum number of modules is only possible in open space when installation conditions 
detailed in DTU and microinverter manuals are fulfilled and the microinverter and DTU are properly 
placed apart as required.

5.1.2  Environmental Requirements for DTU Installation:

•  The DTU should be installed away from dust, liquid, acidic, or corrosive gas.
•  The ambient temperature should be between -20ºC and 55ºC.

If you plan to install the DTU on the wall, please prepare two #8 (4.166 mm diameter) screws and a 
screwdriver in advance.
