I have this 12KW hybrid inverter which comes with a RS232 port, to which I connected the wifi adapter. Using SmartESS, I can get the inverter data. I want to use the inverter in such a way that I can enable charging and discharging at programmed intervals (which I can manually do using the buttons)
My problem is, none of the standard protocols (voltronic) work on this inverter using either mpp-solar or voltronic-homeassistant or its variants.

Connecting directly to the serial port, I can only get responses to the Q1 command (without any CRC) and it (gets the status string. All other commands return NAK. Same with the standard commands (PI18 or others as described in https://github.com/jblance/mpp-solar/tree/master/docs/protocols)
Wanted to try solar-assistant.io, but not sure if it will work at all, asked them but no response. Manufacturer is of not much help either

Any ideas
 
I'm thinking about getting one of these inverters. Was also thinking of monitoring and controlling it with Solar Assistant but the lack of a USB port and only an RS232 port give me pause. Were you able to get it to work?
