Inverter Setup Guide

Overview

The inverter setup is a crucial step that enables your gateway to communicate with your solar inverter. This connection allows for:

  • Real-time power production monitoring
  • Performance analytics
  • Energy production verification
  • System health monitoring

Connection Methods

1. Direct Connection (Modbus TCP)

  • Most modern inverters support this method
  • Uses standard Ethernet/WiFi connection
  • Requires inverter's IP address and port
  • Default port is usually 502

2. Via RS485-to-Ethernet Converter

  • For inverters with only RS485 (Modbus RTU) support
  • Requires additional hardware
  • Converts serial communication to network protocol
  • Maintains compatibility with older inverters

3. Via Modbus TCP Proxy

  • For inverters limited to single connections
  • Allows multiple devices to connect
  • Maintains existing monitoring setup
  • Requires proxy configuration

Setup Instructions

  1. Select Your Inverter

    • Choose your inverter manufacturer from the list
    • If not listed, check compatibility documentation
    • Note: New inverters are regularly added
  2. Connection Details

    • Enter the inverter's IP address
    • Verify the port number (usually 502)
    • Set the device address (typically 1)
    • Test connection before saving
  3. Configuration Verification

    • System will test the connection
    • Verify data is being received
    • Check for any communication errors
    • Confirm proper readings

Common Settings

Default Ports

  • Modbus TCP: 502
  • SunSpec: 502
  • Custom: Check inverter manual

Device Addresses

  • Single inverter: Usually 0 or 1
  • Multiple inverters: 1-247
  • Check inverter documentation or

Troubleshooting

Can't Find Inverter

  • Verify inverter is powered on
  • Check network connection
  • Ensure you're on the same network
  • Try scanning for devices again

Connection Failed

  • Verify IP address and port
  • Check firewall settings
  • Confirm inverter settings
  • Try power cycling the inverter

Data Not Updating

  • Check connection stability
  • Verify device address
  • Ensure proper protocol selection
  • Review inverter configuration
