No monitoring data via 4G Stick

This guide helps troubleshoot issues where your 4G Stick is not providing monitoring data for your Autarco inverter. Monitoring is crucial for tracking your solar system's performance, identifying potential issues, and ensuring optimal energy production.
 
Possible Causes:
  • Power loss or connection problems affecting the 4G Stick or inverter.
  • Malfunction of the 4G Stick
  • Incorrectly configured inverter settings, especially the inverter address.
  • Mobile network connectivity problems or issues with the SIM card.
  • Signal strength problems, potentially due to the 4G Stick's location.
  • Compatibility or setup issues with a Power Export Limiting Device (PELD) if installed.

Before you begin:

Safety First: Working with electrical equipment always involves risks. Ensure you are qualified and follow appropriate safety precautions. Disconnect the inverter from both AC and DC sources before performing any physical inspection or adjustments.

Gather Information: Before starting troubleshooting, have the inverter manual on hand. You should also gather information about the inverter model and serial number, the installation date, and the PV array configuration (number of panels, capacity, and number of strings).
 

Troubleshooting Steps:

  1. Check Power and Connections:
    • Verify that all switches are in the ON position, including the DC switch on the inverter.
    • Ensure that both the AC and DC power supply to the inverter is active.
    • Confirm that the 4G Stick is securely connected to the inverter's communication port. The location of the communication port and its type (4-pin or 16-pin) can vary depending on your specific inverter model; the inverter manual should provide these details.
    • Inspect the 4G Stick and its cable for any signs of physical damage or loose connections.
  2. Test 4G-STICK Functionality:
    • If possible, test the 4G Stick on a different device or network to ensure it is functioning properly. This will help you determine if the issue is with the stick itself or with its connection to the inverter.
    • Consult the 4G Stick manual for specific troubleshooting instructions.
  3. Verify Inverter Settings:
    • Use the keypad and LCD display on your inverter to access the settings menu. The inverter manual will provide specific instructions on navigating the menu.
    • Check that the inverter address is set correctly. This is particularly important in setups with multiple inverters. Be aware that modifying the address when using a WiFi Stick or LAN Stick could interrupt monitoring.
  4. Check External Factors:
    • Verify that your mobile network connection is stable and has sufficient signal strength.
    • Confirm that the SIM card inserted in the 4G Stick is active and has an adequate data plan.
    • Try repositioning the 4G Stick to improve signal reception if signal strength is an issue.
    • Or try using our MyAutarco app to reconnect your monitoring device.
  5. PELD Specific Checks (if applicable):
    • If a PELD is installed, confirm that only one monitoring device is used for the entire system. The monitoring device should be connected to the PELD, not directly to an inverter.
    • Ensure the PELD and inverter firmware versions are compatible with your monitoring setup.
    • Refer to the PELD manual for any monitoring-related troubleshooting instructions.

Verifying the solution:

After completing these steps, check if monitoring data appears in the MyAutarco app. If the data is successfully transmitted, the problem is resolved.
 

If the problem is not resolved:

If the error persists after following all the above steps, there might be an internal fault within the inverter.
 
As a system owner: In this case, contact the inverter installer or distributor for further assistance. You can find the details of your installer in the MyAutarco app.
