House Battery Corrosion
I have finally found a storage unit that has electric. I have been plugged into 50amps since last fall, but the problem I now have is corrosion on my house batteries. Never had the problem before. I clean the batteries, go on a trip then store for a few months and more corrosion. Is this normal ? Thanks.....Gary

How often do you add water? What is the battery voltage when plugged into shore power?
You should not see higher than 13.7 VDC when plugged in. If it's higher, you will have to top off the water more often. This is either an indication your batteries are nearing replacement or, your converter is set too high. Load test on the batteries may be in order. How old are they?
I added 4oz of mineral oil to each cell on mine when I replaced them about five years ago. Since then, I add water every 3-4 months and never have a corrosion issue.

Part of NORMAL battery maintenance is to remove the cables and wire brush or sand the surfaces that Make contact. Cleaning the outside of the connections isn't sufficient.

I do add water frequently. My batteries plugged in are always showing 14 volts. I replaced the house batteries 2 years ago, but when stored and not plugged in, i had a lot of fluctuation from fully charged batteries to pretty low. I had them load tested in March and they were fine, but I am sure that I shortened their life.

You have a problem with your converter overcharging. As stated, it should produce a maximum of 13.7 VDC.

Or you have a bad cell or 2 somewhere. A bad cell will call for a higher charge constantly causing the charger to never go into float. I went through this last fall. Unhooked cables and then checked each cell after several hours. I ended up buying 4 new Trojan T105s at a golf cart place in the Rio Grande Valley-end of most of the corrosion and adding very little water since. Good luck.

I did the mineral oil trick to my U-2200's in about 2004. The batteries lasted till 2010 (OEM in 2002). Here's a couple pictures of them after some 8 years:
