I just purchased.a multiplus 12/3000 120v. I connected it to my Venus GX with a standard Cat5e RJ45 cable. The Venus doesn't see the multiplus. I've tried two different RJ45 cables. I've tried rebooting the Venus multiple times. I've tried turning the multiplus off and on either before or after the Venus restarts. I made sure I was plugged into one of the ve.bus ports on the Venus . The Venus is running 2.58 firmware and the processor firmware code on the multiplus is 2702430.VFD. I believe ve.bus should work correctly.
My multiples also makes a buzzing noise when it is in inverter mode. I assume this is normal, but wasn't sure if it was somehow related.
I removed all other ve.direct devices but that didn't help either. I have an MPPT device and a BMV712 that connect just fine.
Any ideas? Is it possible the ve.bus interface on the Venus or multiplus is defective?
Thanks in advance!
