Understanding your monthly energy report
Spot issues faster and fix them smarter. The Installer Portal gives you the tools to check system performance, run remote diagnostics, and dig into reports—all without stepping onsite. This section guides you through what to look for and how to take action with confidence.
To monitor how your microinverters are performing, go to the View tab and check the Power (W) values. You can navigate across different days and times to better understand the system’s performance.
If you’re not seeing reports, updated data, or live status, open the Devices tab and check the gateway’s status. If it hasn’t reported in over 12 hours, it will show as Gateway Not Reporting. You can also confirm this by reviewing the Last Report column.
Visit the Events tab to see both current and past system events. For more information and troubleshooting steps, click the icon in the Impact column.
Under the Reports tab, you can generate detailed site reports, including information like Grid Profile Settings. These reports can be viewed directly or emailed to the account address.
From the Installer Portal, navigate to the System Dashboard to access a high-level overview of the system. Within this dashboard, the System Diagnostics section allows you to perform remote actions such as rebooting devices or provisioning them again. These tools can help resolve certain issues without requiring a site visit.
Also in the System Dashboard, you'll find the PLC Noise Detection section. Here you can run a noise test to detect any interference on the power line communication (PLC) used by the microinverters and gateway.
In the Graph tab, you can track system production. If meters are installed, consumption data will also be available. You can view production and consumption per phase and compare microinverter data with the meter’s readings—very helpful for identifying discrepancies.
When viewing data by phase, you'll see production and consumption per phase. In three-phase systems, if you see positive values on one phase and negative on another during nighttime, it likely indicates a mix of phases.
Case 1
If you’re seeing negative values on your meter during production hours, enable the data from the microinverters. If the meter shows lower values than the microinverters, it likely means that the CTs aren’t capturing all the production branches—resulting in incomplete measurement. For three-phase systems, this may indicate that the phases are mixed, leading to inaccurate production readings.
Case 2
If production is being fully measured and the phase alignment is correct, another possible cause of negative values during production hours is the CT configuration. If your CTs are set to Load Only and negative values appear only when the system is producing, you’ll need to update the configuration. Go to the Devices tab, click on Enphase Integrated Consumption Meter, and change the CT configuration to Load with Solar.
If the gateway isn’t reporting, it’s often due to internet issues—like weak Wi-Fi, router settings, or setup errors. This section helps you fix connection problems step by step, starting with proper placement and setup.
When activating a system for the first time, always ensure the gateway is installed in a location with strong Wi-Fi signal. If needed, use Wi-Fi repeaters or connect via Ethernet for a more stable connection.
Start by checking the Gateway’s LED lights to identify the issue.

• Ensure the router broadcasts a 2.4 GHz signal. The Gateway does not support 5 GHz.
• If the router uses a combined SSID for both 2.4 GHz and 5 GHz, consider splitting them into separate network names in the router settings.
• Make sure the Gateway is within range of the router.
• Avoid placing it near metal enclosures, thick walls, or other signal-blocking materials.
• Open the Enphase App and follow the prompts to reconnect the Gateway to Wi-Fi.
• You may need to manually enter the 2.4 GHz network name and password.
Reconnect your Envoy S or IQ Gateway to Wi-Fi
• Power cycle both the gateway and the router.
• Wait a few minutes, then attempt to reconnect.
If Wi-Fi issues persist, connect the gateway directly to the router using an Ethernet cable for a more reliable connection.
If the gateway still won’t connect or shows issues with Live Status, there may be a firewall blocking communication. Check how to set up the Gateway if there is a firewall.
If you have microinverters not reporting or you face production issues in one or more microinverters, start with this support guide, which covers the most common causes and fixes. This section also offers quick tips to help you identify whether the issue is due to electrical noise, AC faults, or panel-related problems—so you can troubleshoot more efficiently on-site.
Before replacing a device and requesting an RMA, make sure to follow the troubleshooting procedure and document the issue with clear pictures and videos—such as swapping micros, AC measurements, and LED status. These materials are essential for us to approve the RMA.
What the lights mean
A quick look at the LED on the microinverter can already tell you a lot:
Use the LED status as your first checkpoint during troubleshooting.
Communication over power lines
Microinverters communicate through Power Line Communication (PLC). Electrical noise or interference can disrupt these signals.
You can also cross-check production values to identify communication issues:
What to check and where
AC issues can impact microinverter performance and are often caused by grid instability, wiring faults, or relay problems. Here’s how to quickly check for them:
Use your tools:
Signs of AC Issues:
Panel or microinverter?
Sometimes a microinverter may show signs like not producing at all, producing less than the others, or even producing less than it used to. When that happens, the issue could be with either the microinverter or the connected PV panel.
Lower production isn't always a fault—it can also be caused by shading from nearby trees, chimneys, antennas, or other objects. Keep your surroundings in mind when diagnosing DC-side issues.
To identify the root cause:
Swap the microinverter with another one that is known to be working.
This simple swap test remains one of the most effective ways to troubleshoot and confirm DC-side production issues.
In addition to the tools in the Installer Portal, this section gives you extra tips to identify and fix common metering problems—so you can ensure accurate readings and reliable system data.
Accurate metering starts with correct CT placement. Use the Current Transformer Installation Guide to avoid common wiring mistakes and ensure reliable readings.

Use the Enphase Installer Portal to compare production from microinverters (grey line) and meters (blue line). If meter readings are too low or show night-time production on 3-phase systems, you may have mixed CT phases.
