I just bought a XANTREX POWER 1200 PLUS DC AC POWER INVERTER 2000W
on ebay for less than $100.00 us.
My question is...
Does this unit have a floating ground?
I plan on locating it in my shed with my battery bank and charge
controller. I already have some 8ga wire run in the conduit along with
the #4 wire that I use to run my 12 volt radios etc.
Should I just connect the 110volt outputs of the inverter and rely on
its ground or should I ground the negative side to my ground system?
Thanks

You are not supposed (per NEC) to run low voltage wires (ie, your 12V
feed) in the same conduit as 110V wires, at least as I understand it.

Like I said ...I can not find crap on wireing codes here (other than normal
household) so I am playing it by ear here.
Damn....more wire and more conduit ...It's all the little crap that kills
you...

NEC 300.3(C)(1)? NEC 725.55(D)(1)? Expection: For solar photovoltaic
systems in accordance with 690.4(B)?

As I understand the NEC codes, any voltage below 50 volts is exempt
from the coding.
