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.

I had a PAE 4024 run high voltage so that it wouldn't AC couple at
all. My older PAE does not fluctuate.

Hi all, I’ve had the following issue with a new PAE 4024. It’s ac
voltage will rise and fall about 10+ volts ( 124-115) over about 10
seconds like clock work. Regardless of the load, or battery
SOC/voltage. I checked with a local shop, they also have the issue.
They checked all their back stock and they all did the same thing.
However they had an older one, say 6 months old that didn’t do it.
Nor do any of my previous magnum installs do this. Clients are not
too thrilled with this as lights go up and down in brightness.
Magnum’s response was that this is normal for an off grid inverter
and that somehow this “feature†has to do with it being able to
AC couple better. I’m writing to ask if others have seen this as
well and more importantly if anyone has a fix? Thanks, Jay Peltz
