Please try to use the PC application Watchpower on each inverter. If Watchpower is working you should be able to replicate the communication. Furthermore Watchpower has a debug log so you can have a look at the traffic here.

Why do you expect both inverters are using the same protocol?
from esphome-pipsolar.
Sounds like the second inverter isn't supported by Watchpower because it uses another protocol.

Is there any difference if I use esp2866 instead of Arduino?
Some Arduinos are using a logic level of 5V. The ESP has a logic level of 3.3V. UART-TTL communication should be pretty similar.

is there any PC application for Solar inverter that use different protocol?
I cannot help here.

Hello @syssi, I think that because I did a lot of research on the internet and all results indicate that it uses the rs232 protocol.
like this file:
RS232 communication Protocol for InfiniSolar 3K.pdf
edit :
I am trying to communicate with BlueSun company to send me a document about protocol but no response from them.

Thank you my friend for replying.
I tried Watch Power when I plug the Falcon inverter with a USB cable, it appears in the Watch Power app but when I plug second inverter it does not appear on my PC.

Today, I went to another friend who works in an electronics store, he give me permission to try on different brands of inverters,
The inverter that works default protocol is SAKO, FALCON, and PowerLand, RENOVO, but the inverters that not works are MUST, BlueSun.

is there any possible way to know what is the protocol that the inverter works on ??
I have the catalog and all the paper, but there is nothing about communication only the use of rs232.

I will update the state of the issue if I get any solution.
