The IQ Battery 5P may ship with one of two cover variants: Variant A (two conduit entry points) or Variant B (one conduit entry point). While both variants meet all functional and safety requirements, Variant B requires special attention during installation. Since it provides only a single conduit opening, installers must route both power and control communication cables through the same conduit.

For outdoor installations, ensure proper ingress protection when using one conduit for both cables. Use flexible conduits with sealing hubs rated for outdoor applications. Cable glands are not suitable for outdoor use. This variation does not affect product performance, but correct routing is essential for compliance and reliability.

Variant A - Two conduit entry points

Variant B - One conduit entry point

Proper installation and commissioning are essential to ensure reliable operation of Enphase FlexPhase battery systems.

By installing new, higher-wattage panels with IQ8 Microinverters, installers can unlock the full potential of sites where IQ7 Microinverters have already been installed.

Supported system configurations include Solar Only and Solar Plus Batteries without backup; supported batteries include the IQ Battery 5P.

Further details:

An additional IQ Gateway is not required when expanding an IQ7 Microinverter site with IQ8 Microinverters. An automatic software upgrade during commissioning of the newly added IQ8 Microinverters will ensure compatibility with the existing IQ7 Microinverters present at the site.

Commissioning of the new IQ8 Microinverters requires the latest Enphase Installer App and IQ Gateway software version.

Download the latest user manual explaining the wiring scheme, to ensure the smooth operation of all the devices in the system and to follow the local wiring regulations. The following instructions apply specifically to the installation and wiring of new IQ System Controllers. Existing commissioned and operational Enphase Energy Systems do not require any wiring modifications.

This brief provides further detail about supported system configurations, as well the technical information required to evaluate sites and plan the installation of Enphase Energy Systems in Australia and New Zealand. 

While installing the IQ System Controller 3 INT, use the gateway replacement feature in the Enphase Installer Portal or Enphase Installer App to move the microinverters from the existing gateway to the IQ Gateway embedded in the IQ System Controller 3 INT.

Once this is done, power down and remove the legacy gateway from the site before commissioning the system via the Enphase Installer App. This is a must to avoid conflicts between the legacy gateway and the IQ System Controller 3 INT.

To learn more about gateway replacement, refer to the tech brief.

Before turning on the IQ System Controller 3 INT:

1. Ensure the System Shutdown Switch (SSD) is wired to the IO board terminal of the IQ System Controller 3 INT.
2. Ensure the SSD is in the ON position until the system is commissioned via the Enphase Installer App. The switch is to be operated only after the system is fully commissioned.

   

3. If the bottom LED inside the IQ System Controller 3 INT is glowing solid red, indicating a shutdown state, contact Enphase Support for further assistance.

This release is available for in-progress Enphase Energy System installations using the latest version of the Enphase Installer App and as an over-the-air update for already installed systems. Read the full release notes for more information.

Learn more about the steps to complete a software update: 

1. Before you leave for the install site, open the Enphase Installer App and confirm you are running version 3.27.0. If not, then download the latest update from the Apple App Store or Google Play Store.
   

2. In the Installer App settings, check to see if the IQ Gateway has already automatically downloaded version 7.03.120. If not, tap ’Download’. We recommend performing this step in the office over Wi-Fi prior to going into the field.
   
   

3. Once you arrive on-site, connect to the IQ Gateway and tap ’Update Software (v07.03.120)’.   
   
   

Ensure proper grid profile propagation and the ability to disable power production in the IQ Gateway with two short steps:

1. Update to the latest version of the Enphase Installer App.
2. Update the IQ Gateway software to version 7.00.92 or later through the Enphase Installer App before provisioning the devices. Software updates can take up to 15-20 minutes.
