Hello, I am sorry if someone question that. I have solar system with - EASUN 5.5kw Hybrid Inverter MPPT 48V - 4x solar panels Suntech 440w - 4x Gel battery /12v 150ah/ - and Victron Energy SmartShunt 500A/50mV. When I ordered my inverter I ordered it with wifi module for monitoring. But before weeks I found the Solar Assistant app. And tried for the first time to connect my inverter to pc because I saw can monitor my inverter with Watchpower app and if I can monitor inverter from pc, I will buy the app because I want more information about my system. The inverter came with RS232 cable (RJ45 male to female RS232 on the otherside). I bought usb to rs232 cable and tried to connect pc to inverter, download the driver, app, all and tried to connect them. But when connect the inverter to pc not show me on the left side inverter like connected com device. I read and tried with SolarPower but same result. Bought other cable USB/RS232 and the result was same. Tried to convert RS232 to TTL (with chip max3232) and connect via usb to ttl cable (with chip PL2303HX) but the result was same. Tried way with max3232 converter and ftdi module, same result. Finally tried to connect inverter to old computer with male com port, but the result was same, nothing. And I don't know what to do and I need help. Thank you for help in the advanced.
