I happen to have a converter I got in 2011 that I do not expect to use again, so I tried it. It says it has RP protection and it has four 40 amp fuses for that.

(the photo in that is not a 100 amper--ignore that bit)
I used a set of cut-off jumper cables for the connection. Voltage at the clamps 13.75. I have a pair of 27s in the garage on a Float charger from back when I used these batteries with the RV.
So--being real brave (or stupid) I clamped the converter backwards to the battery bank. Neg post first if that matters. Very Big sparks at the pos battery post and nasty popping at the converter, plus burning smells. Yipes! Removed clamps from battery bank, voltage at the clamps now zero, zip, nada.
Unplugged converter 120v, took out the four blown 40 amp fuses, replaced with four good ones, plugged the converter 120v back in.
Voltage at the clamps now 13.75 Everything is good with the converter. Put it back in the attic. 27s back on their Float.
You are welcome. :)
