[RE-wrenches] DR>FX Compatibility Problem

[R. Walters]

I quit selling Staber, as they changed the design substantially over  
the years. The last one I had would NOT run reliably on a Xantrex SW+  
Inverter. Kept smoking circuit boards. The days of a Staber running  
off a Trace U612 are long gone. (I guess they went to the same  
dinosaur land that the old Kohler gennys and decent profit margins went)
To your list of possible causes, you should add:
7) Staber has become a finicky appliance that  will drive an honest  
solar installer  crazy.
