Hi all,
I need to choose an Inverter for my new solar system but I would like to be able to read data from HA locally, without any internet connection and I don’t want to sync data with the manufacturer’s servers.
Considering the available native integrations for HA, which of these should I choose?
Please keep in mind that I would like to avoid CT Clamp sensors to read the data.
Thank you
Fronius works fine for me, but I did write the integration, so 
They would also support ModbusTCP if you needed more frequent or detailed data.
But in the end I’d choose by which one is best suited for your PV system. SolarEdge is known to be good for panels in different alignments because of their “optimizers”. Fronius was the choice for me because i have all panels facing in the exact same direction and no obstacles casting shadows on some of them.
Can’t say anything about SMA or Huawei.
But in the end solar energy yield > data yield.
