MI Toolkit
MI Toolkit is one of the toolkits that come with the S-Miles Cloud App. It can
be used for on-site inspection after the PV power station is complete, so that
the operation of the microinverter can be monitored without Site Creation.
For more operation details regarding MI Toolkit, please refer to “User Manual
for DTU-Lite-S SE”.

(refer to “Quick Installation Guide for S-miles Cloud Online Registration” for

Warning
– Only qualified personnel can install or replace the DTU.
– Do not attempt to repair the DTU by yourself. If the DTU breaks down, please
