Problem with parallel model

[damihighlander]

Greetings, a big thumbs up for this project. I have an issue with inverter model POW-HVM5.5K-48V-LIP (with parallel) - according to powmr website it also supports rs232 wifi dongle however for some reason i cannot get any response from modbus protocol, i checked the rs232 connections with an multimeter - it seems to have good connection - baudrate is set to 2400 n 8 1bit, Modbus ID Setting (setting 25) is default set to 001, i used ModScan32 for protocol testing (address 0001, id 1 lenght 100) - still nothing. Could you guide me in reading registers from this device? I have some experience in reading data and sending commands via mqtt to VMIII and MAX II hybrid inverters (if someone needs help with these particular models) powmr seems to be diffrent atleast in rs232 modbus.
