Growatt Inverter RTU Protocol II Modbus register map
Growatt inverter Modbus RTU map from the document Growatt Inverter Modbus RTU Protocol V1.24. It lists holding registers (settings, protection limits, identity) and input registers (PV, grid, energy, fault and storage data). Page 3 of the document says which register ranges each inverter family uses (TL-X/TL-XH MIN, TL3-X MAX/MID/MAC, storage MIX/SPA/SPH); this file covers the common first group, the 3000 block for TL-X and TL-XH, and the main storage block, and many rows are marked for particular models. The same register number can mean different things on different families, so check the family ranges first.
- Protocol
- Modbus RTU (RS485)
- Defaults
- Default 9600 bps, 8 data bits, no parity, 1 stop bit; baud rate selectable through holding register 22 (0 = 9600, 1 = 38400). Slave addresses 1 to 254 (holding register 30, initial value 1; 0 is broadcast). Minimum command period 850 ms (1 s suggested); maximum read or write length 125 words. Functions 3, 4, 6 and 16 (p. 3, 5, 8).

- Version V1.24 (85 pages; the change record lists version 00 dated 2020.4.28 and the effective date field is blank); copy hosted by a third party; vendor-hosted copy could not be fetched. The distributor file name reads Protocol_II V1_24 English
Address base. Register numbers are printed as plain decimal (holding 0 to 124, input 0 to 124, 3000 and so on) and the ranges on p. 3 are given as 0~124. The document does not state whether the table number is the number placed in the request or one higher, and gives no worked request example. Treat the numbers as zero-based protocol addresses and check with a known register, for example input register 0 (inverter status) or holding register 30 (communication address). Holding registers are read with function 3 and input registers with function 4. Address 0 in the manual is address 0 on the wire.
Word order. Two-register values are listed as separate H (high) and L (low) rows with the high register at the lower number, for example Ppv H at 1 and Ppv L at 2. The document gives no worked hex example, so the high-word-first order is inferred from the register names. Each register is a 16-bit unsigned integer unless the table marks it otherwise; the document does not state the sign of most values, so check temperatures and reactive power on the device.
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. In Modbus Poll set Word order to AB CD.
- 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.
