SolarEdge Shadow Mapping Error Causes & Troubleshooting

Troubleshoot SolarEdge shadow mapping errors. Learn causes, solutions, and prevention tips for your residential solar monitoring app.

Frequently Asked Questions

•How do I check the Wi-Fi signal strength of my SolarEdge gateway?

The SolarEdge monitoring app typically displays Wi-Fi signal strength information under the gateway's network settings. Alternatively, you can use a Wi-Fi analyzer app on your smartphone or computer to measure the signal strength at the gateway's location.

•What is the recommended internet upload speed for a SolarEdge monitoring system?

SolarEdge recommends a minimum internet upload speed of 1 Mbps for reliable data transmission from the gateway to the cloud platform. Higher upload speeds are beneficial for systems with multiple inverters or advanced monitoring features.

•How often should I update the firmware of my SolarEdge inverter and gateway?

It's recommended to update the firmware of your SolarEdge inverter and gateway whenever new updates are available. These updates often include bug fixes, performance improvements, and security enhancements. Check the SolarEdge monitoring app or portal for notifications about available firmware updates.

Technical Background:

The SolarEdge monitoring system relies on continuous data acquisition from inverters and power optimizers. Data flows via Modbus or TCP/IP to the SolarEdge cloud platform for processing and display in the mobile app. "Shadow Mapping" errors typically arise during the cloud-side data processing stage. Communication interruptions, data corruption, or inaccurate geolocation data can contribute to this issue.

Symptoms:

The SolarEdge monitoring app displays a "Shadow Mapping" error, preventing accurate visualization of solar panel performance and energy production data. Historical data might be incomplete or inaccurate.

Possible Causes:

Inconsistent or weak Wi-Fi connectivity between the SolarEdge gateway and the internet.
Issues with the SolarEdge cloud platform impacting data processing algorithms.
Firmware bugs in the SolarEdge inverter or gateway affecting data transmission.
Incorrect time zone settings on the SolarEdge gateway, causing data misalignment.
Corruption of historical data stored in the SolarEdge cloud database.
API communication failure between the inverter and the SolarEdge monitoring platform.

Solution:

1

Verify a stable internet connection at the SolarEdge gateway location. Test Wi-Fi signal strength and consider using an ethernet connection for improved reliability.
2

Check the SolarEdge monitoring portal for any reported service outages or maintenance activities.
3

Ensure the SolarEdge inverter and gateway firmware are updated to the latest versions via the SolarEdge monitoring app.
4

Confirm the correct time zone is configured within the SolarEdge monitoring portal and gateway settings.
5

Restart the SolarEdge inverter and gateway by cycling the AC and DC disconnects (following NEC rapid shutdown protocols and safety guidelines).
6

Clear the cache and data of the SolarEdge monitoring app on your mobile device and log back in.
7

If the issue persists, contact SolarEdge support for further assistance and potential cloud-side data correction.

Safety Warning:

Never attempt to modify or repair any hardware components of the SolarEdge system. Improper modifications can void the warranty and create safety hazards. Always adhere to proper DC disconnect procedures and NEC rapid shutdown requirements before performing any maintenance. Secure your SolarEdge portal account with a strong password and enable two-factor authentication to protect your system data.

Prevention:

• Regularly update the firmware of the SolarEdge inverter and gateway to benefit from bug fixes and performance improvements.
• Monitor the stability of your internet connection and consider implementing a cellular backup for uninterrupted data transmission.
• Periodically review the data accuracy in the SolarEdge monitoring app to identify and address any potential data discrepancies early on.
• Ensure the SolarEdge gateway has sufficient ventilation to prevent overheating, which can impact network connectivity.

Expert Tip:

Access the SolarEdge monitoring portal via a web browser on a computer for more detailed diagnostic information compared to the mobile app. Check the inverter logs for any error messages related to data transmission or cloud connectivity. Also, verify the inverter's communication settings via the configuration tool (installer access required).
