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)
