Probably I will sniff MaxTalk communication.
Does anyone communicate with MaxConnect ?

But do you also have a description of the errors that can occur in the invertor? Thx, Marc Hello there,

nice job. But do you also have a description of the errors that can occur in the invertor?
Thx,

What a inverter returns if I ask something that has not? I believe that returns a byte with a blank space. Is it normal? Do you happened? I have a question.
