X1-Boost, X1-Mini, X1-Air modbus documentation

[Goblaski]

I've gotten the public Modbus protocol info for the X1-Boost, Mini and air. Any use for it? If so I can share it.

I've so far have not been able to get the X1-Boost I have at home working, but I will try with a shorter cable first. If it works I will let you know.

hey, do you have working integration with solax x1 boost? I have x1 boost gen3 + wifi dongle v3 but I am not able to use this integration yet. thanks

[mapotn]

unfortunately I have no success even with rs485 USB adaptor, all still looks same in logs etc.
should I use same pins 4,5 in RJ45 connector?

trying to use /dev/ttyUSB0 path as it looks correct in hw details in HA:

Official documentation: Solax Power X1-BOOST Single phase inverter Modbus-RTU comms protocolV1.0 - Public version.pdf

This seems to be Modbus @wills106. For my case I expect a dodgy cable at the moment, but I will try a with short cable and a laptop next to the inverter some time next two weeks to see if it works. My current UTP cable is about 20-30 meters long and running through the house. Might have damaged it during install so I will try a short one first.

Oh also:
Internal code:
A: 1.38 D: 2.22

[Goblaski]

Firmware Arm 1.37 and above is supported. So technically it should support ModBus. I think I got firmware ARM 1.41 (recieved the firmware from Solax). So if it doesn’t show up in the menu you might want to get the the latest firmware. I am unfortunately unable to access the inverter at the moment so I can’t check the setting.

[michaeljaddy]

Perfect thank you! Just waiting for the installer to send over the PIN number to access the settings and will give it a shot.

[wills106]

The default is 2014 or 6868 unless they have changed it:

homeassistant-solax-modbus/custom_components/solax_modbus/plugin_solax.py

Lines 919 to 930 in a2f970a

	SolaxModbusSelectEntityDescription(
	name = "Lock State",
	key = "lock_state",
	register = 0x0,
	option_dict = {
	0: "Locked",
	2014: "Unlocked",
	6868: "Unlocked - Advanced",
	},
	allowedtypes = HYBRID | AC,
	icon = "mdi:lock-question",
	),

Edit: Assuming the Air / Boost / Mini is the same pin as the Hybrids.

Perfect thanks for your input folks! Up and running:
