Tump,
All I know is that AFCIs work off of the radio frequency signatures of arcs.
If your inverter has a lot of high frequency noise, typical in off-grid
inverters, it may be seeing this noise and thinking it is an arc. Marv
Dargatz, may have something to add on this. Also, relays in your charge
By off-grid inverters do you happen to mean square wave and/or modified sine
wave inverters? If so, I have been struggling with a similar issue. I have
tried to get both/either Cutler-Hammer AFCI and GFCI devices to work with a
Magnum MM1212 AE (modified sine wave) with no luck. All GFCI and AFC
Hello Wrenches,
We have a 2KW portable unit with one Outback GVFX3524. Intermittently, we have
a problem feeding GFI breakers.
Its the strangest thing, sometimes it trips GFI's and other times it doesn't.
Aside from the possibility that some of the GFI's aren't wired properly we
haven't been
I am out of the office until 06/04/2010.

I recently talked to the tech support folks at Magnum about AFCI
breakers and they didn't know of a single one that would work with
modified square wave inverters. The AFCI requirement for all new
residential construction may finally be the death of modified square
wave inverters.

We've had no problems with Outback inverters and AFCI breakers, other than the
inverter can't actually generate the 70 amps necessary to make an AFCI trip.
(an inspector's AFCI tester didn't trip when expected) I think there should be
an exception to the AFCI requirement, when the power supply m

We like the Pentanut from Bryce Fastener. Spendy (about $2each) but a nice
replacement for a standard 1/4-20 nut, and they make the only socket that
will fit the nut.

Wayne,
That's because the GVFX3524 goes not provide any support for ground
switching. If you install a Ground switching relay and isolate the
input neutral from the output neutral bus's this will get rid of this
problem...
On a side note how did you get a utility (or have you) to approv
It sounds like you have a single GVFX feeding a load center w/ Multi wire
Branch circuits. You will need an auto transformer on the OB power center
to feed both L1 and L2.
You will also need to do the ground switching and neutral isolation that

For some reason we have started to get a bunch if installs that required AC coupling due to long distance to ground mounted solar array and inverter from main house and battery inverter system.
Although we have tried several combinations of hardware, the Sunny Boy at the array and a Xantrex XW
