This manual contains important instructions for use during the installation and maintenance of the IQ8 Series Microinverters. Important: Enphase IQ Series Microinverters require the IQ Cable. An IQ Gateway is required to monitor the performance of the IQ Microinverters and configure them to be compliant with certain Authority Having Jurisdictions (AHJs).
IQ Relay is rated for 20 A, whereas multi-phase IQ Relay is rated for 25 A. DANGER: Risk Do not use Enphase equipment in a manner not specified by the manufacturer. Doing so may cause death or injury to persons or damage to equipment.

Enphase microinverter. damage. The Enphase microinverter is not protected from damage due to moisture trapped in cabling systems. Never mate microinverters to cables that have been left disconnected and exposed to wet conditions. This voids the Enphase warranty.
• Microinverters and all DC connections must be installed inside the array boundary. Enphase further requires that the microinverters and DC connections be installed under the PV module to avoid direct exposure to rain, UV, and other harmful weather events.
9.5 mm (3/8") in white on a red background. Anti-islanding methodology The anti-islanding methodology used by Enphase IQ8P Microinverters is listed by UL and tested in accordance with IEEE1547-2018 and UL1741-SB. IQ8 Series Microinverter uses the Group 1 method of anti-islanding based on the definitions provided...
IQ Gateway collects production and performance data from the IQ8P Microinverters over onsite 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 39 IQ Batteries.
60°C (140°F). Ease of design PV systems using Enphase microinverters are very simple to design and install. You will not need string calculations or cumbersome traditional 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.
Enphase IQ Cable Planning and Ordering. 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...
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.
ENV-IQ-AM3-3P. • Enphase Installer App: Download the Enphase Installer App, open it, and log in to your Enphase Account. Use it later to scan microinverter serial numbers and connect to the IQ Gateway to track system installation progress. To download it, go https:/ /enphase.com/installers/apps...
Enphase IQ8P Microinverters Enphase microinverter installation Installing the Enphase IQ Series Microinverters involves several key steps. Each step listed here is detailed in the following pages. Step 1: Position the IQ Cable Step 2: Position the junction box Step 3: Mount the microinverters...
220 VAC three-phase 198 to 242 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.
When using UL 2703 mounting hardware, use the manufacturer’s recommended torque value. Step 4: Create an installation map The Enphase installation map is a diagram of the physical location of each microinverter in your PV installation. Copy or use the blank Enphase installation map to record microinverter placement for the system, or provide your own layout if you require a larger or more intricate installation map.
Enphase IQ8P Microinverters After you have created the installation map, use the Enphase Installer App (mobile app) to record serial numbers and configure the system. For details, refer to “Detect the Microinverters” in the help topics of the Enphase Installer App.
Disconnect a Microinverter. Step 7: Terminate the unused end of the cable Terminate the unused end of the Enphase IQ Cable as follows. IQ Terminator body A. Remove 13 mm (½ inch) of the cable sheath from the conductors. 13 mm Use the terminator loop to measure 13 mm.
Enphase IQ8P Microinverters Step 10: Enphase Energy System configurations The Enphase Energy System with IQ8P Microinverters can be used to form the PV solar grid- tied configuration. Enphase Energy System PV solar grid-tied For grid-tied mode, after the IQ8 Microinverter installation, energize the system as follows: A.
Enphase Installer Portal, during system registration, or through the Enphase Installer App at any time. You must have an IQ Gateway to set or change the grid profile to be compliant with certain jurisdictions.
Method: Clear this error using the Enphase Installer Portal • Log in to the Enphase Installer Portal and access the system. • Click the Events tab. The next screen shows the current “DC Resistance Low - Power Off”...
PV module electrical compatibility with the microinverter. K. Swap DC leads with a known good, adjacent PV module. If, after checking the Enphase Installer Portal periodically (this may take up to 30 minutes), the problem moves to the adjacent module, this indicates that the PV module is not functioning correctly.
M. Verify with your utility that the line frequency is within range. N. If the problem persists, contact Enphase Support at https:/ /enphase.com/en-ph/contact. Disconnect a microinverter If problems remain after following the troubleshooting steps listed previously, contact Enphase Support at https:/ /enphase.com/en-ph/contact. If Enphase authorizes a replacement, follow these steps.

J. Start the provisioning process for the newly added microinverter using the Enphase Installer App and by connecting the Enphase Installer App to IQ Gateway in AP mode. You can then “Start Provisioning Devices” through the Enphase Installer App.
Replacement parts and cabling Enphase IQ Cable planning and ordering The Enphase IQ Cable is a continuous length of 12 AWG, double insulated, outdoor-rated cable with integrated connectors for microinverters. These connectors are preinstalled along the IQ Cable at intervals to accommodate varying PV module widths. The microinverters plug directly into the cable connectors.
Technical data Technical considerations Be sure to apply the following when installing the Enphase IQ8 Series Microinverter system: WARNING: Risk of equipment damage. You must match the DC operating voltage range of the PV module with the allowable input voltage range of the microinverter.
20 mm x 1.1 mm x 6.5 mm (0.7" x 0.04" x 0.25") Enphase connector ratings Enphase connectors on the cable assemblies in the following table have a maximum current of 20 A, a maximum OCPD of 20 A, and a maximum ambient temperature of -40° to 79°C (-40° to 174.2°F) and are rated for disconnection under load.
