Solaredge

The following guide describes how to configure the Modbus TCP settings for SolarEdge inverters and how to test the connection.

Prerequisites

Network connectivity (Ethernet or WiFi)
Physical access to inverter
Web browser
Mobile device with camera

Configuration Process

Physical Access Setup

Locate the on/off switch on the inverter
- Usually has a red cap
- Typically found near the bottom left of the inverter
Push the switch to the left (P ) for 1 second
Release the switch

Network Connection

Locate the QR code on the right side of the inverter
Scan the QR code using your phone's camera
Connect to the WiFi network indicated by the code
- Note: You may receive a notification about the network lacking internet access
- If this occurs, select "Use network anyways"

Modbus Configuration

Open a web browser
Navigate to http://172.16.0.1/
Find the "Communication Settings" section
Enable the Modbus TCP option
Note the port number shown
- Usually 502 or 1502
- Write down, you'll need this for future reference

Important Notes

Document the port number for future use
Maintain network connectivity during configuration
Ensure proper physical access to inverter switches

Troubleshooting

Connection Issues

If unable to connect:

Verify QR code scan was successful
Check WiFi connection status
Confirm correct IP address entry

Configuration Problems

If settings don't apply:

Refresh browser page
Verify network connection
Try alternative browser

Testing connectivity (advanced)

After enabling Modbus TCP on your SolarEdge inverter, it's important to verify that the connection is working properly. You can follow our testing guide to confirm the connection. For SolarEdge inverters, try both port 502 and 1502, as the port number can vary between models and firmware versions. The Unit ID is typically set to 1. Make sure to document both the working port number and Unit ID for future reference, as you'll need these for any monitoring setup.
