[RE-wrenches] Magnum inverter issue

[Ray]

I've got quite a few Magnum PAEs installed and have not seen this 
before.  I have one I'm about to install, so I just bench tested it and 
I did see the fluctuation.  It was cycling from 116vac to 122 vac about 
every 5 seconds.  As far as Magnum claiming this is "Normal" off grid 
operation, well, we may be switching inverter brands, because that is 
the "Wrong" answer.  This reminds me of Xantrex's infamous TR inverters 
that caused lights to blink on/off, and fridges to cycle every minute.  
It wears on appliances and customers' nerves.

Normal operation is stable 120 vac 60 Hz, sine wave. period.  I'm 
calling Magnum right now, I don't know what they did, but they need to 
undo it right away.
