"Current power: 0" in log #1

Open shannondpasto opened 3 years ago

Hi.

Just configured the plugin but I'm getting "[16/04/2021, 4:26:20 pm] [Solar] Current power: 0" in the log. I can ping the inverter and telnet to port 502. Home and Eve app says the "switch" is off. Have I missed something?

Thanks, Shannon

Hi Shannon,

What's the model of your Sungrow inverter? I suspect your inverter uses different modbus register than mine...

shannondpasto commented 3 years ago

Hi.

I have an SG3K-D. Seems as though Sungrow did a firmware update last year which has changed things and the standard modbus registers.

Not sure if it's relevant but while researching other options (solar-sungrow and sgemon on GitHub), the ModbusTcpClient doesn't work anymore due to AES128 ECB encryption implemented with the new firmware. The SungrowModbusTcpClient appears to work though.

Thanks, Shannon

Same issue here Shannon, and seems we’ve done the exact same research - got the same info too... SG5KTL-D inverter here.

Hi All, any update on this? I have the SG5K-D, and would love to get this working.
