Highly recommend using solarassistant for this, instead - local server software that install on a raspi, and you hook a usb on the raspi to the WiFi dongle port on your inverter with a serial cable. Don’t provide the inverter itself with any wifi credentials.

Solar assistant has the bonus of interfacing your inverter with homeassistant, and letting it control the inverter/get signals from it (so you can do things like, if grid voltage drops to zero, do xyz)
