Enphase IQ Batteries help keep power flowing even when the weather turns on you or the grid has a bad day. Learn how to get the most out of your IQ Battery during a grid outage.

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.
