Understanding Module Colors and Status Icons in the EI Portal

BRIGHT GREEN = High Wattage

The module is producing at a high level compared to the rest of the system.

In this example, the module is in direct sunlight and producing 182 Watts.

BLACK = Low or No Wattage

The module is producing little or no power.

This is normal at night. During the day, it may indicate a wiring or system issue.

DARK GREEN = Mid-Low Wattage

The module is producing less power than nearby modules. Temporary shading is common, but persistent differences may indicate a system issue.

GREY = Monitoring Data Unavailable

The system is not receiving data from this module.

Gray has the same meaning in every Display Mode. See "If a Module Is Gray" below.

If a Module Is Gray

A gray module indicates that the EI Portal is not receiving monitoring data for that module.

Common causes include:

• A recently replaced Tigo device that has not been updated in the EI Portal.
• A communication issue.
• The module has not yet been discovered.
• Radio interference.

A gray module can appear in multiple Display Modes and has the same meaning in each mode.

For detailed troubleshooting instructions, see Discovery Troubleshooting and Replacing a TS4 Optimizer.

Display Mode: Voltage

ORANGE = Normal Module Voltage

The module is operating within its expected voltage range.

BROWN = Low Voltage production

The module voltage is lower than expected.

This may occur during low sunlight conditions or if there is a problem affecting the module.

DARK ORANGE = Reduced Module Voltage

The module voltage is lower than nearby modules.

Temporary shading is common. If the module remains dark orange throughout the day, the system should be inspected by your installer.

GREY = Monitoring Data Unavailable

The system is not receiving monitoring data for this module.

See section: "If a Module Appears Gray."

*Note: If the module voltage drops below the minimum operating voltage, the module may appear gray because the Tigo device can no longer communicate with the EI Portal.

Display Mode: Current  

Current Display Mode shows the electrical current flowing from each module. Current is often useful for identifying shading or connection issues.

RED = Normal Current

The module is producing current at the expected level.

BLACK = Minimal or no Current

The module is producing little or no power.

This is normal at night. During the day, it may indicate a wiring or system issue.

CRIMSON = Reduced Current

The module is producing less current than nearby modules.

Temporary shading is common. If the module remains crimson throughout the day, your installer should inspect the system.

GREY = Monitoring Data Unavailable

The system is not receiving monitoring data for this module.

See section: "If a Module Appears Gray."

Identify Installed Tigo Devices

For each fully commissioned monitored Tigo TS4 device, a colored bar appears at the bottom of each module in the System View. The bar identifies the type of Tigo device installed on that module.

The bar appears in every Display Mode and does not indicate module performance.
