HTTP request - getting data from inverter

I'm trying to get informations from inverter connected to my local network. It has static IP and
after login through web browser i can read basic informations. Using F12 in chrome i can see that data is
returnet in text/html format.

I was trying to use HTTP request node but i'm continously receiving error about authorization.

Attached file shows web details.

How to set up this node to get the data?

Thank you for any suggestions.
