Anti-islanding methodology The anti-islanding methodology used by Enphase IQ8 Series Microinverters is UL Listed and tested in accordance with IEEE 1547-2018 and UL 1741-SB. IQ8 Series Microinverter uses the Group 1 method of anti-islanding based on the definitions provided...
Page 11 PV array. The IQ Gateway collects production and performance data from the IQ8P Microinverters over on-site AC power lines and transmits the data to the Enphase App through a broadband or cellular connection. The IQ Gateway can monitor up to 600 IQ8P Microinverters and up to 39 IQ Batteries.
Page 12 65°C (149°F). 1.1.3 Ease of design PV systems using Enphase microinverters are very simple to design and install. You will not need string calculations or cumbersome conventional string inverters. You can install individual PV modules in any combination of PV module quantity, type, age, and orientation. Each microinverter quickly mounts on the PV racking directly beneath each PV module.
Page 13 Planning for microinverter installation 2.1 Compatibility The IQ8P Microinverters are electrically compatible with PV modules, as listed in the following table. No enforced DC/AC ratio and maximum input power. Modules can be paired if the open circuit voltage (V ) and short circuit current (I ) of the PV module at the extreme temperatures (lowest temperature for voltage and highest temperature for current) do not exceed the microinverter’s...
Page 14 Select the correct wire size based on the distance from the beginning of the microinverter AC branch circuit to the breaker in the load center. Enphase recommends a voltage rise total of less than 2% for the sections from the microinverter AC branch circuit to the breaker in the load center.
Page 15 Planning for microinverter installation is also important to have insurance that protects against lightning and electrical surges. Enphase has tested the following devices: Leviton 51110-SRG • Schneider SquareD HEPD50 • NOTE: Protection against lightning and resulting voltage surges must be in accordance with local standards.
Page 16 Enphase microinverter installation 4. Enphase microinverter installation Installing the Enphase IQ8P Microinverters involves several key steps. Each step listed here is detailed in the following pages. 1. Position the IQ Cable 2. Position the junction box 3. Mount the microinverters 4. Create an installation map 5.
Page 17 240 VAC split-phase 211 to 264 VAC NOTE: All installations require that you use the Enphase IQ Gateway to commission the microinverters to propagate correct grid profile settings. This will also ensure that the microinverter’s firmware is upgraded whenever a newer version is available.

Loose cables can become a tripping hazard. Dress the IQ Cable to reduce this risk. © 2024 Enphase Energy Inc. All rights reserved. December 2024 IOM-00080-2.0-EN...
Page 21 4.7 Terminate the unused end of the cable Terminate the unused end of the Enphase IQ Cable as follows. 1. Remove 13 mm (½ inch) of the cable sheath from the conductors. Use the IQ Terminator loop to measure 13 mm.

Page 24 IQ Batteries, and the IQ System Controller smart switch. It collects system performance information and transmits that information over the internet to Enphase Cloud. An IQ Gateway is required for Enphase Energy Systems with IQ Series Microinverters. Note the IQ Gateway is included in an Enphase IQ Combiner.
Page 25 Generator Home loads For grid-tied mode, after the IQ8P Microinverter installations, energize the system as follows: 1. Turn ON the AC disconnect or circuit breaker for the branch circuit. 2. Turn ON the main utility-grid AC circuit breaker. Your system starts producing power after a five-minute wait time.
Page 26 200 A. 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.
Page 27 Follow all the safety measures described in this manual. Qualified personnel can use the following troubleshooting steps if the PV system does not operate correctly. WARNING: Risk of electric shock. Do not attempt to repair the Enphase microinverter; it contains no user-serviceable parts. If it fails, contact Enphase Support to obtain an RMA (return merchandise authorization) number and start the replacement process.
Page 28 6.1.2 DC Resistance Low – Power off condition For all IQ8P Microinverters, a solid red status LED when DC power has been cycled indicates the microinverter has detected a DC Resistance Low–Power Off event. The LED will remain red, and the fault will continue to be reported by the gateway until the error has been cleared.
Page 29 WARNING: Risk of electric shock. Always de-energize the AC branch circuit before servicing. Never disconnect the DC or AC connectors under load. WARNING: The Enphase microinverters are powered by DC power from the PV modules. Ensure you disconnect the DC connections, reconnect the DC power, and then watch for the solid green for about six seconds after connecting to the DC power.
Page 30 If problems remain after following the troubleshooting steps listed previously, contact Enphase Support. If Enphase authorizes a replacement, follow these steps. To ensure the microinverter is not disconnected from the PV modules under load, follow the disconnection steps in the order shown: 1.
