SMA Sunny Tripower

Installation

1. 1Enable Modbus TCP on the SMA Sunny Tripower inverter through its web interface or display menu.
2. 2Connect the inverter to the same local network as the ModbusCloud gateway (MCG or MLP series) using an Ethernet cable.
3. 3Note the inverter's IP address and Modbus unit ID, and configure these in the ModbusCloud gateway settings.
4. 4Import the SMA Sunny Tripower template from the ModbusCloud template library and assign it to the gateway.
5. 5Verify that register values appear correctly on the ModbusCloud dashboard, checking that 32-bit reads are aligned starting at register 30201.

Things to watch for

01

Modbus TCP is not responding on the SMA Sunny Tripower. What should I check?

Modbus TCP must be explicitly enabled in the inverter's communication settings. Access the inverter's web interface, navigate to the communication or protocol section, and confirm that Modbus TCP is activated. Also verify that the correct TCP port (default 502) is open.

02

I see unexpected or very large values in the dashboard. Why?

All registers in this template are 32-bit (uint32 or int32), requiring two consecutive register reads. If the byte order or word order is incorrect in the gateway configuration, values will appear garbled. Confirm that the word order matches SMA's convention (typically big-endian).

03

Can I monitor multiple SMA Sunny Tripower inverters with one gateway?

Yes. Assign a unique Modbus unit ID to each inverter and create a separate device instance in ModbusCloud for each one, all using the same template. Ensure all inverters are reachable on the local network from the gateway.

04

Does this template support writing setpoints or controlling the inverter?

No. This template is read-only and does not include any writable registers. It is designed purely for monitoring energy production and device status.
