Info and help on configurations

[Ices-Eyes]

Hi!
I have an HD Wave SE5000H, single phase, no batteries. I've been able to enable the modbus over wifi connection in the inverted, and correctly (i suppose 😅) connected to the integration. By the way I'm not sure how to configure all the options on the integration. On the config page it asks to select some checkboxes (some for batteries and power control) about meter data 1, 2 and 3: what are those related to? Also, what the correct values of polling interval and max export power limit?
And finally, I have 3 controls on the integration, export control limit mode, mode and site limit: what do they need to?

I'm sorry if there is already a guide for that, probably my fault of not having found that :)

Thanks!
