Mike,
If the neutral/ground bond is removed, any outlets on the generator
should also be removed so it can't be used as a portable power supply.

As a check, Larry might disconnect the Generac machine
from the Outback system and everything else, then with machine not
running, check for continuity from the neutral (wide) slot on the GFI
receptacle and the metal frame of the generator.
If there is continuity, the neutral is bonded to ground at the
generator...and is probably also bonded to ground at the first
disconnect in the home. That would explain the GFI trip-out.
I would then suggest to find and remove the bond from generator neutral
to chassis, especially if this machine is hard-wired into the Outback
system then there is a bond elsewhere so two bonds are not needed.

Dave,
The original setup was an 1800 watt Homelite generator with two non GFI
receptacles, no twist lock receptacle
The client had the generator from building their house
It was wired through a fused disconnect to the VFX3524
All worked fine
They tried the same set up with the new Generac 8000 watt inverter
They plugged into a 20 amp GFI receptacle on the generator and it kept
popping the GFI breaker
I did lower the Battery charger AC amps and the AC amps in but it
seemed to make no difference

Larry,
Are you sure it is not a simple overload situation? Have you tried
reprogramming the VFX with a Mate to lower critical values (AC Amps In,
and
Battery charger AC amps)?
Seems strange a 8kW generator to have a 20A breaker protect a load like
a
generator (unless you were plugged into that outlet). How do you have
the
output wired?

Fellow Wrenches,
On an off the grid system we did for a client a year or two back, we
installed an Outback VFX3524 mounted on a Midnight Solar E Panel.
They had a manual pull Homelight generator as back up. All worked well.
Recently the client upgraded to an electric start 8000 watt Generac
generator.
Now every time they start the new generator, the GFI 20 amp
receptacle on the generator pops.
There is probably a redundant neutral to ground bond that is causing
this but I am uncertain on the best approach to remedy this condition
Any recommendations or experience on how to get the generator to
interface with the system?
Thanks
Larry
