    Vlastikz replied to mknecht's topic in Inverters
    Hello, I had a problem with the EASUN SMP2 3-phase connection with USB, the communication was lost, by measuring (with an oscilloscope) I found out that there is a lot of interference from the MPPT inverter, I have long enough cables to the solar panels, I solved it with a ferrite ring 2 to 4 twisted both wires +- z panels to inverters. I also found out that the self-purpose switching from SBU to USB only occurs when the DC bus voltage is higher than 390V DC, this inverter can supply to the grid even if ie parameter 08 disable. Vl.
