Preparing for Installer Toolkit Communications
The following process assumes all Ensemble equipment has been installed in a code compliant
manner, tested for appropriate voltages and are ready to be energized.
 For all products, always follow the SAFETY INSTRUCTIONS and instructions in the Enphase
quick install guides and installation manuals.
DANGER! Risk of electric shock. When energizing equipment in step D, check that Encharge
units are properly wired as prompted. Miswiring can result in a safety hazard. Note that the
ground connection does not have a L1 or L2 connection as this introduces a safety hazard.
 Ensemble is commissioned using Installer Toolkit. Ensure Installer Toolkit is updated to
version 3.X or later:
