I would add the new Exeltech grid tie inverter to that question. I see their ad
in the latest HP magazine, but no info on their website about them, and no
distributor seems to know much about them.
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
Had the exact same thing happen once after we replaced a circuit board in a
FX3524. After some head scratching I went and checked over the AC
connections at the inverter, which my overly helpful client had wired and
found that he had switched the neutral and hot in legs.
Best regards,
Mark
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
Larry,
Sounds like there are two neutral ground bonds: one at the generator
and one at the house. This causes part of the neutral current to flow
on the ground - a guaranteed way to trip the GFI. This is the catch 22
of connecting a portable generator, or one with an outlet, to a house
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.

Allan,
Using a T-240 fed from the 30 amp twist lock, non GFI, outlet with
240 volts and then taking the stepped down 120 volts into the Outback
looks like it would solve the problem of having two neutral to ground
bounds.
It is a little pricey for the extra T-240 needed but it means not
Larry,
One of my points in the HP gennie article is that you get what you pay for,
and cheap generators - in this case, both the Homelite and the Generac -
aren't always a good choice. The added cost of the T240 makes the great
price not so great.
If the customer balks, offer them the article.
We added a T-240 transformer to step down voltage, 240 to 120 VAC into an
older system with a SW4024 this summer, and had input lead balancing issues
till OB had us pull the neutral from the generator to the x-former. This
cleared up some of the issue but not all of it. We even swapped out the
For a test, install a three prong to two prong adaptor on the
attachment plug, and see if the problem persists. The neutral to
ground bond is likely made in the generator as well as in the
electrical service. This will cause a current in the equipment
ground, which will trip a GFCI. It
Hello Wrenches,
Since year end projects are going to keep us crazy busy till year end,
I am breaking with tradition and getting started early on my Christmas
shopping. I have a tradition in my family of giving an ornament to
each family member. Usually something relevant to the years
