Delta Inverter Communications

The Delta M4 that Tesla supplies only seems to have Bluetooth to talk to their little gateway box you need to plug into a ethernet cable. Delta says the M series can have Wi-Fi and ethernet as an option.

I am looking for a way to see what this inverter is doing vs only the aggregated value from all three of my solar systems in the Tesla app.

Has anyone put in the optional communications card and if so could you access the data from the inverter?

Note I have not gotten a PTO for this inverter yet so I am not certain what capabilities Tesla will provide if anything. The Tesla installer basically said it was for FW updates and monitoring by Tesla, but he did not even allude that I would have access to any data from the inverter other than the CT that is monitoring my collection of inverters.

I use the "M professional" app if I want to see info of each inverter. You need to be close to it though for a connection since this is via bluetooth.
Thanks. I too can use that for a spot view of production, but was hoping for something more "historical" and one that I didn't have to "go for a walk" to check on. Plus I would like to capture the output in my computer.

Hello,

I have a Delta M10 and tried plugging in the ethernet port but it doesn't appear to be active. I tried looking at the Delta manuals but it doesn't say anything on how to activate it. Any advice?
Did you log in as a customer and select Network and then Ethernet and then select the Connect button at the bottom? I only use a static IP address for the ethernet so cannot comment on how DHCP might work, but I would think the same.
