Connecting the Enphase Micro-Inverter to the electrical utility grid must only be done after receiving prior approval from the utility company. The body of the Enphase Micro-Inverter is the heat sink and can reach a temperature of 80!C. To reduce risk of burns, do not touch Do NOT disconnect the PV module from the Enphase Micro-Inverter without first removing AC power.
The distributed nature of the Micro-Inverter System insures that there is no single point of failure in the PV system. Enphase Micro-Inverters are designed to operate at full power at temperatures as high as 65!C (150!F). The inverter housing...
WARNING: Risk of electric shock. Normally grounded conductors may be ungrounded and energized when a ground fault is indicated. Installation of the Enphase Micro-Inverter System involves the following key steps: Installing the AC branch circuit junction box Attaching the Enphase Micro-Inverters to the racking...
GEC. WARNING: Use electrical system components approved for wet locations only. NOTE: Please refer to the Enphase website for a list of approved PV module racking systems. NOTE: The Enphase M175-24-240-S Micro Inverter is designed to operate with most 72-cell PV module configurations;...
The Enphase Installation Map is designed to be a diagrammatic representation of the physical location of each Enphase Micro-Inverter in your PV installation. This information will be used by Enphase to provide you with detailed information about the performance of your PV system and graphically visualize your PV system on the Enphase Enlighten website.
Enphase will create a graphical representation of your PV system on the Enlighten website. The Enlighten web server will provide you with detailed information regarding the performance of your PV system (please go to www.enphaseenergy.com for more information on the...
Proper operation of the Enphase Micro-Inverters can be verified via the Emu. Troubleshooting Adhere to all the safety measures described throughout this manual. Enphase recommends the following troubleshooting steps in the event your PV system does not operate correctly: WARNING: The Enphase Micro-Inverter contains no user serviceable parts.
Make sure that all the AC switches in the junction boxes are functioning properly and are closed. If the problem persists, please call customer support at Enphase Energy. Disconnecting the Enphase Micro-Inverter from the PV Module To insure the Micro-Inverter is not disconnected from the PV modules under load, adhere to the following procedure in the order shown: Turn off the AC disconnect on the AC branch circuit junction box.
Technical Data WARNING: It is required to match the DC operating voltage range of the PV module with the allowable input voltage range of the Enphase Micro-Inverter. WARNING: The maximum open circuit voltage of the PV module may not exceed the specified maximum input voltage of the Enphase Micro- Inverter.
