I’m looking into solar systems and found a good offer on a system that includes an inverter and battery from bluecarbon. However, I couldn’t find any details about connectivity over WiFi . The system has a usb port and two ports that look like RS-485.

My question is: if the inverter doesn’t have WiFi connection, would it be possible to add it using an extra dongle? Or do I need a raspberry pi style system over the usb port?
