Just out of curiosity, shouldn't those little 300W inverters be grounded in some
way? I just picked
up one made by Xantrex and it has two 3 prong outlets, non-GFCI.
Nice quiet operation by the way. I thought my compact fluorescent would be
buzzing away.

I've read of people frying the units when they tried grounding the 'neutral' On
the units I use in the garage, I've grounded only the case of the inverter to
the negative side of the batteries. It seemed to make the radio plugged into it
a bit quieter.

Thanks Mike, I will have to give that a try as I have noticed that it has
affected the noise level
on my shortwave and HF receivers.

OMG! do ***NOT do it that way. Ground the case of the inverter (It should be
anyway or not be connected). If the batteres are grounded fine, or ground
them sperately if your inverter input will allow it, without letting the
magic smoke out.
You ***never*** want to run an electrcal neutral to the metal frame or case
of any appliance. Any electrical faults or disturbance is brought right to
the case or frame of the equipment. If you are leaning against the metal at
the time you could get electrocuted. This is an electrical no-no, a code
no-no, and a stupid thing to do or tell somebody to do.
I doubt any electrical person worth shit is that stupid to even imply this
on purpose even for the purpose of an idiotic troll's joke . Get that
clarified first.
Best of luck

Yeah, after all, I'm sure that in the ca. 10 years since the code was
changed, _every_ 3-wire dryer outlet in the USA has been changed and
_every_ clothes dryer rewired to seperate ground from neutral.
The only reason NOT to connect neutral to the case, is because neutral
is elevated above ground by the current (I*R losses) flowing in the
circuit. In the rare case where you provide a better connection to
ground than a 14ga or bigger wire, there could be a hazard.
