Troubleshoot the meter setup

If you get stuck in the installer app while testing the meter setup, here is a list of things you can check:

• The grid meter must measure the total load, including PV generation, general household consumption, and battery usage, including charging and discharging.
• The PV meter should only measure PV generation, not battery or any load.
• Verify that the current transformer for each phase is installed on the same phase as its corresponding voltage measurement wire. This means that:
  • L1 matches 1
  • L2 matches 2
  • L3 matches 3
    

    Note: You cannot trust the colors of the cables, and it may be necessary to verify the matching of the phases using a multimeter. The voltage should read 0 V.

• The meter must be connected to N (neutral), L1, L2, and L3 to measure all three phases properly. It will not work correctly if only one phase (L) and neutral (N) are connected.
  Note: Some meters, for example, EM530 and EM540, don’t have the N terminal.
• Ensure that the current flow direction is consistent for all current transformers (CTs). The arrows on the CTs must point in the same direction.
  
• On meter, power measurements can be checked as follows:
  • Load1 represents the grid and is connected to the A1 plug on the meter.
  • Load2 represents the PV and is connected to the A2 plug on the meter.
    Note: This functionality only works if the meter is configured for system 3P or 2.3P - it will not work with the default settings.
• Use a twisted pair cable for the Modbus RTU lines, a single pair.
• The Modbus RTU connections must be swapped: A → B+ and B → A-. Once the meter is set up successfully, both the TX and RX signals will be visible, indicated by the red and green LEDs.
