And I don't see the power of each inverter. Total power and energy work.

My system has DS3-L inverters and ECU-R PRO. I collected some data hoping you can find out why it's not working as expected. In the ZIP you find 3x webpages with the realtime data (full set of data, two with an inverter not reporting data likely because of low irradiation), a webpage with the power history, and some screenshots. report.zip

Let me know if you need more.

I checked again and I noticed that the same error

return self.coordinator.data.get("inverters", {}).get(self._uid, {}).get("voltage", [])[0] causes sometimes missing voltage, or "0 V", or missing temperature, and maybe more.
