There are inverters with local only monitoring and control. I have one integrated locally with home assistant. You can also add an external current transformer and monitor the production with that independent of the inverter.
Not the person you responded to, but for a current monitor you could look at e.g. Shelly devices.
I have a Shelly Pro 3EM three phase current meter device on my home battery connection just to get more accurate data into Home Assistant because the battery provider doesn't provide it. (In hindsight I should've bought a different battery install but that's not something I can change after the fact...)
