SMA Sunny Tripower 60 Modbus register map
The SMA Sunny Tripower 60 is a three-phase commercial PV inverter. Through the Inverter Manager gateway it exposes a SunSpec inverter model 103 map over Modbus TCP with AC and DC measurements, energy yield, temperatures and vendor status and event words.
- Protocol
- Modbus TCP
- Defaults
- Modbus TCP on port 502. The Inverter Manager answers at unit ID 125 and inverters at unit IDs 126 to 167 (older firmware below 1.45 used 1 and 2 to 43) (p. 12, 56).
- Addresses in the manual
- 1-based register numbers (wire address is the number minus 1)
- 32 and 64-bit values
- Not stated in the manual
- Registers listed
- 49
- Checked against
- STP60_SHP75_STPS60-SunSpec_Modbus-TI-en-15, Version 1.5
Address base. Register numbers start at 40001 in the SunSpec profile; the manual says to subtract 1 to get the address to use in a request, so 40001 is read at address 40000 (p. 12). For example 40001 in the manual (SunSpec map identifier "SunS") is address 40000 on the wire.
Word order. The manual says data is sent big-endian, high byte first within each register (p. 13), but does not state the word order of 32-bit values.
Modbus Poll and the Modbus protocol itself count from 0. The "Wire address" column is the number to type into Modbus Poll.

Scale is the number to multiply the raw value by to get the unit. Types with more than one register (32 and 64-bit) follow the word order above.
Open in Modbus Poll
- Download the Modbus Poll blocks file.
- Open Modbus Poll, connect to the device and set its unit ID. The manual does not state the word order for 32-bit values. Check one known value (a voltage or a counter) and switch the setting if it reads wrong.
- In the blocks panel on the right, click Import CSV and pick the file. CSV import is a Pro feature. Without Pro, Modbus Poll polls the first 20 values of your blocks.
- The wire addresses are already in the file, so there is no 0-based or 1-based conversion to do.
Once the values look right, export the tag list to Ignition, Kepware, Node-RED, Home Assistant or Voltrus SCADA.
