Troubleshooting an Enphase system

Need help troubleshooting your Vivint Solar system with an Enphase inverter? You’ve come to the right place. Follow the below steps to troubleshoot your solar energy system, so we can help you generate clean energy for you and your household.

Step 1. Check your solar devices

The first thing we’re going to do is check that all of your solar devices have been properly activated. To do this:

    1. Locate your AC Disconnect. It’s usually on the outside of your home, or in your garage.

    1. Ensure that the lever on the side of the box is pulled up in the “ON” position.

    1. Go to your electrical breaker box. It could be inside your home, on the outside of your home, or inside your garage.

    1. Open the breaker box and look for your solar breakers. They may be labeled “solar,” “solar breaker,” “pv,” or “photovoltaic.” Check to ensure the solar breakers are switched to the “ON” position. (Note, the “ON” position is normally the direction facing inwards, towards the center of the breaker box.)

    1. Depending on your area or the set up of your solar energy system, we may have installed additional solar breakers in a secondary box near your electrical panel. If you see a grey or metal box, open it and check to see if it contains other solar breakers. To open the grey box, grip the two latches at the side and pull them towards you until they pop open. On the metal box, there is a little ring at the bottom. Push the little ring in while simultaneously pulling down on the front face of the box. It should slip down and rotate open.

    1. Check to ensure the breakers are switched to the “ON” position.

Step 2. Identify your Envoy model

In order to effectively troubleshoot your solar energy system, we need to understand which type of Enphase monitor or “Envoy” we installed for your solar energy system. To do that:

    1. Locate the weatherproof box near your AC disconnect or electrical panel.* To open it, grip the two latches on the side of the box and pull them towards you until they pop open.

    1. Inside the box, you should see a small device that looks a little like a computer.

If your device is white and pill-shaped, it means you have an Envoy R. Click the link to go to the next step in Troubleshooting an Enphase system with an Envoy R.
