Annoying PWM sound from Xantrex inverter
I finally got my Xantrex ProWatt SW 2000 installed into my rig. Functionally, everything seems great. I can run the hair dryer (on 800W setting anyway) and microwave at the same time. I finished...

It's the pulsed cycling that caused the noise vs a constant voltage.
Voltage sense was a general comment not related to the noise. Voltage sense is a small set of wires that connects from the battery post to the controller. There is vitrually no amps so the controller knows the battery voltage and will adjust the charging for the battery. Otherwise the controller is not aware of the wiring voltage loss and the battery will be charging at a lower voltage.
A remote temperature probe will also allow the controller to adjust the charging based on battery temperature.
