Solis (Ginlong) Grid-connected PV inverters (RS485 protocol) Modbus register map
The Solis RS485_MODBUS protocol for its grid-connected PV inverters in all power ranges, for machines manufactured after mid-2023. It gives read access to energy counters, DC and MPPT inputs, phase values, status and fault bit fields, and read and write access to the clock, the on or off command and the active power, reactive power and power factor controls. Solis publishes its hybrid inverter Modbus table as a separate document, which this file does not cover.
- Protocol
- Modbus RTU over RS485 (function codes 0x03, 0x04, 0x06, 0x10)
- Defaults
- Slave address 1 to 99, 9600 baud, no parity, 8 data bits, 1 stop bit (p. 4). At least 300 ms between acquisition frames and 700 ms between control frames. The document recommends at most 100 bytes (50 registers) per frame (p. 5). Unimplemented registers inside the valid range read as 0x0000 without an exception, and writes to them are discarded with a normal response (p. 5). Only one write action is allowed per frame, so function 0x06 is recommended (p. 5).

- Ver3.7 (PDF title: ModbusRTU Communication Protocol for Grid-connected Inverters_Ver.3.7_EN), revision V000B000D001 dated 2026/6/16, Ginlong (Solis). Hosted by Solis and linked from the Solis Service Center article 'Modus table for grid and hybrid inverters'
Address base. The document prints decimal register numbers (for example 2999, 3000, 35000) and its function code table says 0x04 covers 30001-39999 and 0x03 covers 40001-49999, but the frame examples show the printed number used as the wire address with no offset: section 6.2 reads 'Reg. Start Address (2999)' as 0x0B 0xB7 (0x0BB7 is 2999) and returns the product model and DSP version, section 6.3 does the same with function 0x03, and the Appendix 4 frames write 3068, 3069 and 3070 as 0x0BFC, 0x0BFD and 0x0BFE and 3080 as 0x0C08. Registers 5.1 are read with function 0x04 (input) and 5.2 with 0x03, 0x06 and 0x10 (holding). The same number can appear in both tables as different registers (for example 3050 and 3051). Address 35000 in the manual is address 35000 on the wire.
Word order. Section 3.1 states for 32-bit values that the high word comes first and the low word second, and that the high byte precedes the low byte within a register.
Modbus Poll and the Modbus protocol itself count from 0. The "Wire address" column is the number to type into Modbus Poll.

Section 6.11 labels its frame address 3053 but the bytes 0x0BEA are 3050. The unit column printing 0.10% conflicts with the remark and is not used. Set register 3070 to 0xA1 first, see Appendix 4. |

The unit column printing 0.10% conflicts with this and is not used. Section 6.13 is internally inconsistent: its frame carries 0x2710 but its parameter table shows 0x03E8 labelled 10000.

Appendix 4 says to set register 3070 to 0xA2 first, and its step 2 text names register 3082 although its example frame writes register 3053 (0x0BED). |

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.
