Not sure this Sofar is supported via the pysolarmanv5 library if I understand this workaround correctly - https://github.com/jmccrohan/pysolarmanv5/issues/18
Hi, thanks for answered. That's the point. Reading some information, many issues come with Sofar Inverter. It doesn't even works with solarman add-on... Concerning CRC, and after reading parts of your code, you call data sensor by number from 1 to XXX. Bus address iaw sofar's datasheet , are something like 0x02%%. Do you think this is the reason ?
0x02 seems like 2 in hex. No idea what they meant with the %%
Their workaround was to use a cabled solution on the RS232 port (RS485 will likely also work)
So doubt its the registers that is the problem
Hi, % came from me. Meanings number of your choice. Addresses start from 0x200 to 0x245 in hex (see attached) I will try with RS485, but there some issues also. Whatever be proud of your add-on, Solarman's one doesn't work neither. You can close that topic if you want. Thanks. SOFARSOLAR ModBus-RTU Communication Protocol.pdf
@Excalibur83 did you get RS485 to work?
Hi, not yet, lack of time.
