Do Inverters Normally Make Noise  

Question:

I have a parallax 55amp model 7355 series 7300 that when plugged in to power it has started to make a high pitch hum. I assume its the inverter making the noise. Does that sound correct and what the correct replacement part fir this unit? Thanks

Expert Reply:

It's actually normal for inverters to make noise so what you described isn't sign of a problem. The replacement converter section for a Parallax 73355 is the part # PD4655V.
