Hello Steve,
In my case, I tightened the voltage window to 110 lower, 125 upper
and the transfer delay to 30. This made no difference. I did not
confirm SETUP/FX/INPUT ...ac transfer control set to GEN.

William,
Check to make sure what Input you have selected… go to SETUP/FX/
INPUT… Verify that you have the Ac Transfer control set to Gen.
Make sure that you have adjusted the transfer delay cycles in the
right screen... ADV/FX/GEN under Transfer delay cycles… I would
set this to 0.
As Mick said.. Check the Lower limit on the AC Voltage… ADV/FX/
GEN… AC2 Gen Lower Limit I would adjust this up to 110-112?
What does he have the cool down timer set to?
I would suggest 5-10 minutes Look under… ADV/MATE/AGS/SETUP… I
would set this to at least 5-10 minutes just to let the genset cool
off before shutting off.

Wrenches:
I have a customer that has a problem with a new generator. He has
two VFX3648 inverters in Outback stacking. He acquired a new
generator, a Kohler 12RES, a reputable make and model. Below is a
description of the problem:
The 12RES seems to be operating OK except for one problem. At the
end of a charging cycle, when the gen automatically shuts down and
load goes back to the inverters, all lights, TVs, etc., flash, one
TV shuts off, and a GFI trips. This has happened every time. It
did not happen with the 15RES or the smaller back-up gen (which was
disconnected manually). With the 15RES the same GFI would
occasionally trip while the unit was charging and handling house
load, but never at the auto shutdown point. I replaced the GFI,
but it still trips. There are three GFIs in the house, but only
one--always the same--trips.
I suggested he adjust the AC2/Gen transfer delay to a lower
number. He reduced it to minimum and this did not resolve the
problem. I also had him verify that the AC source is selected as
generator, which it is.
Do you have any suggestions?
Thanks in advance,
William Miller
