Installation Procedure; Step 1 - Measure Ac Voltage At The Electricity Network Connection - enphase M215 Installation And Operation Manual

Installation Procedure

Installing the Enphase Microinverter System involves several key steps. Each step listed below is detailed in the
following pages.
Step 1 – Measure AC Voltage at the Electricity network connection
Step 2 – Install the AC Branch Circuit Junction Box
Step 3 – Position the Enphase Engage Cable
Step 4 – Attach the Microinverters to the Mounting Rail
Step 5 – Dress the Enphase Engage Cable
Step 6 – Connect the Microinverters
Step 7 – Terminate the Unused End of the Engage Cable
Step 8 – Connect the Engage Cable to AC Junction Box(es)
Step 9 – Complete the Installation Map
Step 10 – Connect the PV Modules
Step 11 – Build the Virtual Array
WARNING: DO NOT connect Enphase Microinverters to the electricity network or energise the
AC circuit(s) until you have completed all of the installation procedures as described in the
following sections.
NOTE: Enphase Microinverters will not begin exporting power until the Envoy Communications
Gateway is installed and has detected all of the microinverters at the site. In addition, the grid
profile must be configured and the Envoy must have propagated these settings to the
microinverters. For instructions on this procedure, refer to the Envoy Installation and Operation
Manual at http://www.enphase.com/support/downloads.
Step 1 – Measure AC Voltage at the Electricity Network Connection
Measure AC line voltage at the electricity network connection to confirm that it is within range. Acceptable
ranges are shown in the following table.
Single-Phase Service
L1 to neutral
NOTE: Be sure the Engage Cable you are using matches the electricity network connection at
the site. Use 5G2.5 Engage Cable at sites with three-phase service, or use 3G2.5 Engage
Cable at sites with single-phase service. Check the labelling on the drop connectors to verify
the voltage type.
