[RE-wrenches]hum

Thanks Everyone for the DC250 hum information.  This question really shows 
how the wrenches network can ferret out lots of information to get the whole 
answer.  I think Dave finally hit the nail on the head with the comment about 
running both conductors thru the same conduit or connector entering and 
exiting the box.  That is the only difference in my setup at home versus the 
ones I have installed for customers.  They have all entered and exited out of 
the same hole.  My system has the cables from the batteries coming in two 
separate knockouts on opposite sides of the box and the cables to the 
inverter exit out of two 1" romex connectors on top about an inch or so 
apart.  Guess I have to get used to the Hum or do a little rework.
