Backwoods sells the buck boost transformers for a reasonable price.
I have to add belatedly that as bomb proof as the venerable DRs were, they
indeed never charged well from cruddy generators. I had one once that made 0.5
amps at 12 volts DC.
The culprit as you already pointed out: Peak voltage w
Sure, Jay, but what does one of those puppies cost (I have never
used one)? If the main reason for using a DR instead of a sine-wave
inverter is lower cost, adding a transformer to improve charge rate
kind of negates any argument for using one of these, doesn't it?

Brian,
I didn't check with a voltmeter; used an outlet wiring tester. Only
one light is illuminated on the outlet tester - L1 to neutral. So
there isn't enough voltage from L1 to ground to operate a neon bulb.
Ground and neutral must be isolated by more than 100 kohms, or the L1
to ground n
Kent,
Thanks for that info.
Have you tested for voltage between the L1 and ground while the generator is
running, or just tested for continuity between neutral and ground when not
running?
I wonder how much Honda paid the City of LA for that sticker :)

Brian,
I also have observed that the Honda EU1000i and EU2000i inverter
generators do not have a neutral-ground bond. Considering that they
are intended as a portable power system and have a three-prong plug it
does seem strange that there is no bond. There is also no GFI
protection which is
HI All,
If the voltage from the generators is low ( probably) then a old trick is to
use a buck/boost transformer to bump it up the voltage.
This trick has the advantage that it doesn't have the hz be too high.

Mick,
Raising the engine RPM will also increase your frequency above 60Hz, which
could injure any electronics running in the house, so be careful there.
Allen,
You mentioned that the inverter/generators have no bond between the neutral and
the frame. I don't see how they can get away with that
Thanks Jeff, That could be the explanation. Outback has metering
issues with the Mate too. When I talked to a tech support about he
fact that the Mate on my system seemed woefully inaccurate, she
chuckled and affirmed that the were pretty approximate.

Although operating on a different voltage (230V) in this country, I noticed a
huge variation in charge rates using DR's with generator voltages on systems
that had been in a while. The generators would gradually drop their output
voltage over time as air filters clogged etc. Once they got down
I knew Allan S. & Brian T. would be among the first to chime in with helpful
observations. My recollection, however, was that prior efforts with portable
generators had worked OK with DR sets...and I know of one setup like that
which is working OK in my home county for sure. (That's a portable with
Brian makes a good point, although I'm not sure it's the cause of
these issue. All of the portable gennies I have seen have the
neutral bonded to the chassis/frame internally. This can't be
correctly tied into an inverter system, as this arrangement creates
a ground loop

Mick,
Are you sure that the neutral is isolated from the frame on that "portable"
generator?
If so, it's a strange generator indeed.

Mick,
You have missed one fundamental point: The DR (and earlier Trace
mod-square series) gulp only the peak of the AC supply waveform when
charging. They need 164V AC at the peak of the waveform at rated
charging load to supply full rated DC current. A small dip in AC
Greetings, Mechanics~ Please review my problem du semaine and chime in if
you are so inspired.
My prior experience with the DR series Trace inverters could be summed up in
two words: practically bombproof!

Good questions, Jason.
No. Yes (2008 NEC 690.47(C) & (D)).
Alternative considerations that might result in a "maybe": Does the system
in question have storage (i.e. batteries)? Is your POCC on a Delta system?

system, you m
Wrenches,
Questions: Does the PV GEC have to be bonded to the ground electrode system at
the same point as the utility service equipment GEC? Is there a code section to
back this up?
Additional info:
1. The DC side of the inverter is a separately derived system and
therefore needs a GE
Doesn't the additional layer of even low iron glass block near 7-9% of solar
