Ginlong Solis 4G Inverter

Use cases

• Monitor real-time active power and total energy production on a cloud dashboard for your solar customer.
• Set inverter power limitation remotely to comply with local grid feed-in regulations.
• Create an alert when inverter temperature exceeds a safe threshold to prevent damage or downtime.
• Track grid frequency deviations over time to identify power quality issues at the installation site.
• Verify that the power limit switch is active after a remote configuration change without visiting the site.
• Compare total energy production across multiple Solis 4G inverters in a portfolio view.

Installation

1. 1Connect the Modbus gateway (MCG or MLP series) to the Solis 4G inverter via the Ethernet port used for Modbus TCP communication.
2. 2Ensure Modbus TCP is enabled on the Solis inverter by checking the communication settings in the inverter menu or via the commissioning tool.
3. 3Assign a unique Modbus slave address to each inverter if multiple units share the same network segment.
4. 4Import the Solis 4G Inverter template into your ModbusCloud project and configure the IP address and port of the inverter.
5. 5Verify that Active Power (address 3004) and Total Energy (address 3008) return plausible uint32 values spanning two registers each.
6. 6Test the writable Power Limitation register (address 3051) by setting a value and confirming the change on the Power Limit read register (address 3049).
