Yes. I have 16 panels (with RSD units), going to my Growatt MIN 6000TL-X. (Underpowered. I don't produce 6kW. I may add more panels later if I need them.) If hooked up correctly, when you turn on the Inverter the panel should come on and display No AC and go into standby if you are not connected to the grid but you should see the expected voltage for each string. If you are in standby mode and you see the correct input then you must be hooked up correctly.
The output goes across the 240V Main. I used an RMA device for service side connection. If you are connected load side you need to go across the 240 V, which normally means 2 breakers to get both sides of the panel, just like your two breakers connected to the mains. (Your panel splits the 240V into two 120V parts. Looking at the unpopulated panel it is literally split in two. That's what split and single phase means in the US.) You should output properly when your service provider gives the go-ahead to connect to the grid and you turn it on. You should not need anything else. You don't really need the wifi datalogger, but it is nice. (The wifi datalogger and shine phone app work great, but you need to make sure it points to the US server if you are in the US.) If it's just sitting there in Standby on a nice sunny day, and you can see the input is correct, then you probably have the output hooked up incorrectly.
My service has a big red wire, a big black wire, and a big green wire coming in that measures about 240 V across the red and black wires. The output from the Growatt has a plug with L1, N, and Gnd. L1 to Red, N to Black, Gnd to Green. When the Growatt senses the 240V, it starts to come out of Standby and turn itself on the rest of the way to operate properly. The panel will show it is outputting as expected, depending on the voltage and current the panels can produce.
