add new connection type ModbusRTU #43

Closed andysu closed 2 years ago

andysu commented 2 years ago

for cable connection as many inverters may connect via cable, but no tcp

in this case you may connect many inverters to 1 logger. (I have logger with 3huawei+1 solis inverters by one line)

I have no way to test this. It should be possible, but don't want to release it with out a good testing beforehand

andysu commented 2 years ago

propose my help. I have many inverters via tcp and via rtu I can give you remote access to my loggers

some example via modbusrtu (pymodbus script)

basking-in-the-sun2000 commented 2 years ago

don't have any way to test this. Just added what I think is needed for rtu connections. Let me know if this works for you

There is a new branch; testing https://github.com/basking-in-the-sun2000/solar-logger/commit/1af38e06056c8aa0ed594d376be4954b7484d834

the info registers should only be written only when a value changes, unless you restart the program.

What errors are you getting? The only value that looks off is I_A. A 4000A phase current sounds a bit high unless you are a utility company.

Also, though it is ok, your insulation resistance seems low. Did you set the grid to your location? You have grid id 1 (China NB/T 32004), so just wondering?

andysu commented 2 years ago

I_A I_B I_C values fixed. Ins resistance - ok in my case grid code 1 (NB/T 32004 - its china magic -only in private messages)))

but ModbusRTU - working!
