Hi:
we have maintained a open source project for solar pv monitoring github , all the energy meter can be integrated in if they meet these two requirements
1 bi-directional measurement
2 api support
Thanks for your attention
demo: http://ha.iammeter.com:13000/ or http://grafana.iammeter.com

Build an Open Source local PV monitoring system with Home Assistant
Build an Open Source local PV monitoring system with Python-InfluxDB-Grafana
This is very cool!
I do the same thing using Node-red, influx and Grafana, I also have HA so I just push some of the sensors to that as well for convenience.
My inverter is just a Growatt MIN series but I managed to work out the modbus protocol so I can poll it every 5sec.
That is also cool.
But please note that ,as far as I know, many manufacture of inverter do not use standard modbus RTU protocol.
you can use telegraf to poll inverter, send it to influxdb and also to a file/mqtt from where you send pvoutput also. (another idea)
