Outback Power AC voltage fluctuation [RE-wrenches]

[Jason Lerner]

<x-flowed>
Hello Jay,

I had a similar situation with a quad stack. I adjusted the output  
voltage of each VFX to the Fluke (there was quite a range),  and then  
calibrated the Mate to show the Fluke Voltage,  and then put the VFX  
that had the most different voltage in port #4 to come on last,  and  
everything works pretty good now.  Maybe you could tune the output  
voltage with enough room to avoid the fridge fan coming on?
Best,

Jason Lerner
