I have 2 LV6548 inverters. can anyone confirm that to use S.A. and have it see both inverters, each inverter need its own serial/usb connection to the raspberry. even when operating in parallel, they each need there own connection ?
 
for your mpp 1 cable should be sufficient ( it is for mine)


"The standard USB cable that came with the inverter is used. SolarAssistant can read both inverters through a single cable plugged into one inverter."

thats why I only ordered 1 wire but SA only seems to have the 1 inverter, how do I get it to see the other ?
 
yes, I believ so, Im 2p1 on first and 2p2 and 180 degrees on other, and get 120 and 240 at the ac panel
Texican, did you ever get your 2nd inverter to show up? I have the same setup, and while I can see links for both inverters under the graphs, all of the values for inverter 2 are zero.

I am using 2 of the comm cables, one to each inverter and then both to the raspberry. are you using 1 or 2 cables ?
yes my system is working fine now

Thanks for the reply and sorry for the delayed response, I was out of the country for a couple of weeks. Yes, I am only using 1 USB cable, I will switch to 2 and see what happens.
 
Yes I have 2 Deye in parallel with 2 USB cables to the SA working great.
Hi, I have two deye inverters 8 and 5 , so do I connect 2 separate usb to the Pi and will it show the collective data or I have to switch inverters . thanks

If the inverters are paralleled together, connect both to the Pi. It will show collective data. If they are not paralleled together. I believe that you need two Pi's. As they would be separate plants.
 
I have the same setup and same question, only with 2 Growatt inverters. I only see 1 inverter in SA.
So I guess I need to connect the second Growatt inverter to the pi as well via USB.

Question: is the USB cable from the inverter to the pi a normal USB cable? In other words: do regular USB cables (i.e. to connect a printer to your PC) also work?

regular cables will work, within your inverters there is an usbtoserial adapter
