Support for solax X1-1.1-S-D(L) #33

Closed marti85 closed 1 year ago

Hello, I have a Solax inverter Model X1-1.1-S-D(L) version Manager.1.07 Master: 1.08 to which I have connected an RS485-to-TTL module and a Wemos D1 mini pin TX (GPIO1) and RX (GPIO3) . Unfortunately I cannot recover the data from my inverter. See logs: log With my oscilloscope I see signals on the TX / RX pins and I see the TX led of RS485 converter blink periodically. It looks like my inverter modbus is not active. I tried passwords 2014 and 6868 but I have no option for modbus, only DRM (disable) Could you help me ?`

If it's a Solar X1 Mini the RS485 port is enabled per default. There is no menu item about RS485 and/or the Modbus address at the settings. Did you double-check your RJ45 jack? Which RS485 converter module do you use? Did you set the baud rate of the logger to 0 to avoid using GPIO1/3?

The inverter doesn't respond if it's off because of no sun / darkness. The inverter responds to RS485 requests only if it's sunny.

Yes i check the RJ45, I connect the pin 4 (A+), 5 (B-) and 7 (GND) on this module : https://fr.aliexpress.com/item/1005003498933608.html I set the logger to 0 like this : logger: baud_rate: 0 level: DEBUG maybe i will change the RS485 module...

Please double-check the RJ45 pinout. Don't trust the colors of your cable because of the different standards. I assume it's a connection/RS485 module issue.
