Is is advisable to leave the converter on at all times or when should I switch it off?  I have a switch by the breakers to turn converter on and off but am not sure why or when I would want to do that. 

I was told this converter has been given the name of a “Battery Boiler” so maybe that has something to do with it. 

I do not see a need to replace converter since it is working but not sure I want to risk killing batteries if that is the case. 

Also it was suggested I install a charger that uses house batteries to charge engine batteries to eliminate the need to merge batteries for charging.  Thanks Tom I do like this idea.
