Enphase Inverter: New System Setup Guide

Last reviewed

Quick answer

To turn on a new Enphase solar system, switch on the solar breaker in your main panel, turn the outdoor disconnect to ON, then open the Enphase combiner (IQ Controller) and make sure every breaker inside is ON. Allow up to 5 minutes for the status lights to come on and production to start.

What you'll do

Turning on an Enphase system takes four steps, done in order: the solar breaker, the disconnect, the Enphase combiner, and a quick check of the status lights.

Step 1: Find the solar breaker in your main panel

Open your main electrical panel (the breaker panel).
Find the breaker labeled for solar. It is often marked with a black label tag.
Make sure it is in the ON position.
Some systems don't have this breaker, depending on how they were configured.

Step 2: Turn on the disconnect switch

Find the outdoor disconnect switch near your main panel.
Flip it to ON.
Check for a screen or light to turn on. That means power is flowing.

Step 3: Power on the Enphase combiner (IQ Controller)

Find your Enphase combiner box. It may also be called the IQ Controller.
Open the panel and make sure every breaker inside is ON.
Status lights on the device will start to come on as the system powers up.

Step 4: What do the Enphase status lights mean?

Light	What it means
Light 1 (Wi-Fi or cloud icon)	Your system is connected to the internet.
Light 2 (lightning bolt icon)	Your system is producing power.
Light 3	Usually stays off. Installers use it for service checks.
Light 4	Your microinverters are running with the correct grid settings.

Allow up to 5 minutes for all lights to turn on and for power production to begin.
