Xantrex Buzzing. Loud.

I was dumping the tanks and heard a loud buzzing that I discovered was coming from the inverter (SW2012). I turned off the battery charger portion and the buzzing went away. Then I got to thinking that it had been a couple of months since I checked the water in the batteries. While adding water, I came across blue corrosion on one positive terminal on the rear right battery. I pulled it off, cleaned it up with baking soda, reinstalled it and turned the charger back on. No more buzzing!
