Service Type and Voltage: L1-L2 240 VAC Split-Phase 211 to 264 VAC 208 VAC Single-Phase 183 to 229 VAC NOTE: All 208 VAC installations require that you use the Enphase IQ Gateway to commission the Enphase Microinverters to propagate correct grid profile settings for 208 VAC trip points. B.
IQ8 / IQ8+ / IQ8M / IQ8A / IQ8H Micro Installation and Operation Each Enphase Microinverter, IQ Gateway, and IQ Battery have a removable serial number label. Build the installation map by peeling the serial number labels from the microinverter mounting plates and placing the labels on the map. You will also place the Enphase IQ Gateway and IQ Battery serial number on the map after installation.
IQ8 / IQ8+ / IQ8M / IQ8A / IQ8H Micro Installation and Operation WARNING: Risk of electric shock. Risk of fire. Install sealing caps on all unused AC connectors as these connectors become live when the system is energized. Sealing caps are required for protection against moisture ingress. NOTE: If you need to remove a sealing cap, you must use the Enphase Disconnect Tool. See Disconnect a Microinverter” on page 27.
IQ8 / IQ8+ / IQ8M / IQ8A / IQ8H Micro Installation and Operation F. Attach the terminated cable end to the PV racking with a cable clip or tie wrap so that the cable and terminator. Do not touch the roof. WARNING: The terminator cannot be re-used. If you unscrew the nut, you must discard the terminator. Step 8: Complete Installation of the Junction Box A. Connect the Enphase IQ Cable into the junction box. B. Refer to the wiring diagrams on page 47 for more information.
IQ8 / IQ8+ / IQ8M / IQ8A / IQ8H Micro Installation and Operation • Enphase Wireless communication kit enables direct communication between IQ Battery, IQ System Controller, and the Gateway using 2.4 GHz frequency. The kit is connected to one of the USB ports on the IQ Gateway. • An Enphase Mobile Connect™ cellular modem is required unless already present to ensure the best performance of your system. The cellular modem connects to a USB port on the IQ Gateway.
IQ8 / IQ8+ / IQ8M / IQ8A / IQ8H Micro Installation and Operation Enphase Energy System PV Solar Grid Agnostic – Sunlight backup In the PV Solar Grid Agnostic configuration in Enphase Energy System, IQ Smart controller smart switch is installed on the line-side of the main load panels. This allows a properly sized Enphase Energy system to provide power to all loads in the main load panel in the event of a grid outage and PV solar presence.
IQ8 / IQ8+ / IQ8M / IQ8A / IQ8H Micro Installation and Operation In the home essentials backup (main load panel) configuration, IQ System Controller is installed on the line-side of the main load panels rated up to 200A. This allows a properly sized Enphase Energy System to provide power to all loads in the main load panel in the event of a grid outage. In this configuration, the IQ System Controller can be configured with a main breaker to act as the service disconnecting means.
