SolaX SolaX X3-Hybrid G4 Modbus RTU template

SolaX X3-Hybrid G4

Three-phase hybrid inverter for PV and home battery, with grid meter, backup output and battery control.

The SolaX X3-Hybrid G4 is a three-phase hybrid inverter that converts PV power, charges and discharges a home battery and supplies backup power when the grid fails. This Modbus RTU template reads PV, battery, grid and meter values, energy counters and fault codes, and lets you set the work mode, battery limits, charge periods and export limit from ModbusCloud.

If a device is not in the library yet, we build the template for free as soon as we have the register data.

Number of installations (optional)

Use cases

  • Show PV power, battery state of charge and grid feed-in of every installation on one dashboard.
  • Send an email when the inverter fault code or the BMS fault code is not equal to 0.
  • Keep a year of history of daily solar yield, feed-in and grid import to explain the energy bill.
  • Raise the minimum battery SOC in self use mode from the portal before a planned grid outage.
  • Switch the work mode to feed-in priority or back to self use with an automation on a time schedule.
  • Check run mode and off-grid values after a grid outage to see whether the backup output took over.

Installation

  1. Connect the RS485 lines of the inverter to A and B of the ModbusCloud Gateway, with termination at both ends of the bus.

  2. Check in the inverter settings that the Modbus address is 1 and the baud rate 19200, or note the values you use.

  3. In ModbusCloud, add a Modbus RTU device on the Gateway with 19200 baud, 8 data bits, no parity, 1 stop bit and the address, then import this template.

  4. Check that Run Mode reads Normal and that PV power and battery state of charge show plausible values.

  5. Import the SolaX X3-Hybrid G4 Settings template on the same address if you also want to read back the current settings.

Things to watch for

The inverter does not answer on the RS485 bus. What should I check?

Compare address, baud rate and parity: the default is address 1 at 19200 baud, 8N1. Swap A and B if nothing comes back, and check the termination at the ends of the bus. The inverter accepts only one Modbus master on its RS485 line, so disconnect other loggers on the same line.

Energy counters or feed-in power show huge or negative jumps.

All 32-bit values of this inverter are sent low word first. The template reads them that way. If you build your own registers, set the word order to low word first, otherwise the two halves are swapped and the value is wrong.

Why do I not see my new setting in the readings after writing it?

The inverter uses separate addresses for writing and for reading settings. This template contains the write registers; the SolaX X3-Hybrid G4 Settings template reads the settings back on the read addresses. Import both on the same Modbus address to write and verify.

How often can I write the work mode or SOC limits?

Many settings are stored in the inverter EEPROM, which has a limited number of write cycles. Write only when a value really changes, not every few minutes from an automation. Writing registers from ModbusCloud is switched on per gateway on request.

Some phase values stay at 0 on my inverter.

The register map covers both the X1 and the X3 models. Registers marked X1 only return values on single-phase inverters, those marked L2 and L3 only on three-phase models. Parallel slave data stays at 0 without a parallel system.
