Enphase Enlighten App Showing No Data — Fix

What Does This Error Mean?

Enlighten showing no data usually means the Envoy gateway has lost its internet connection and cannot upload production data. Check the Envoy's status lights, restart the Envoy and your router, and confirm the Envoy's internet LED is green.

Affected Models

Enphase Envoy-S Metered
Enphase Envoy-S Standard
Enphase IQ Gateway
Enphase IQ Combiner

Common Causes

Envoy lost its internet connection — most common cause
Router replaced or password changed after an ISP upgrade
Enlighten app logged out or account session expired
Enphase cloud service outage
Envoy firmware update in progress — data upload paused temporarily

How to Fix It

Check the Envoy internet LED.

Look at the Envoy's front panel LEDs. The Internet LED should be solid green. If it is amber or red, the Envoy has no internet connection — the router or network credentials are the issue.
Restart the Envoy and the router.

Unplug the Envoy for 30 seconds, restart your home router, then plug the Envoy back in. Allow 10–15 minutes for the Envoy to reconnect to the Enphase cloud and begin uploading data.
Check whether production is actually happening.

In the Enlighten app, look at the last updated time. If the app says Last Updated 2 hours ago and it is a sunny afternoon, the system is still producing but just not uploading new data. The Envoy stores data locally and uploads when reconnected.
Log out and back in to the Enlighten app.

An expired app session can cause the app to display stale or no data even when the system is working. Log out of the Enlighten app completely, then log back in and check whether current data appears.
Check for an Enphase cloud outage.

Enphase occasionally has cloud service maintenance that prevents data from appearing in the app. Check the Enphase status page or the Enphase community forum to see if other users report the same issue.

When to Call a Professional

If the Envoy status lights indicate it is connected but Enlighten still shows no data after 24 hours, the Envoy's cloud authentication may have expired. Contact Enphase support to re-link the system.

Frequently Asked Questions

Enlighten shows no data for 3 days — has my system stopped producing?

Not necessarily. A data gap only means the Envoy was not uploading. If the Envoy reconnects, it will upload the stored data from the gap period and the charts will fill in retroactively. Check the Envoy's internet LED first.

Enlighten app shows today's data fine but all historical charts are blank — why?

This is usually an app display glitch or a slow data load. Try pulling down to refresh the chart screen, or switch between day, week, and month views to force a reload. If history remains blank, log out and log back in to the app.
