How to make the Ethernet to Serial communication cable for the Voltronic Axpert RCT solar inverter

[@abusam1]

thank you for the great demo, how did you figure out the inverter RJ45 pins map, if no documentation is available? I tried to test pins with multimeter randomly but I could not figure it out

What type of the exchange protocol is here? Modbus RTU, CAN bus or just COM on RS-232?
