3.5 Local Install Assistant

Local Install Assistant is a new function integrated with MAC

DTU. Please download

the Installer App (for installer/distributor use only) first.

MAC

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.
