I installed a Xantrex Echo-Charge some months ago and ever since we get a buildup of white sulfuric powder on battery tray components but not the batteries themselves. It only shows up where there is unpainted metal including a paint chip or two. So far I've cleaned it up with baking soda and water.
The biggest offender has been the threaded mounting stud at the front of the chassis batteries. I hadn't checked it in a month or so and this time there was so much powder it looked like some alien fungus.
The batteries are clean, no sign of boiling over or other leaks or any trace of corrosion.
There was no problem before the Echo-Charge was installed. It functions to spec every way I can measure. It's almost as if the battery tray has become charged somehow. I double checked all the ground wires and tray isolation and all seems okay. I could not measure any voltage between the trays and earth ground.
Anyone have any ideas?
