I have been looking for a replacement of my older DC-AC inverter to go
camping and hook up inside my truck and wired up as code with the natural at
ground and case ground potential. Going over several DC-AC Sinewave Power
inverters there seems like there is only a few that DO a good job without
noise riding on the output, and provide the kind of output that I need. The
requirement I was looking for was that the NATURAL of the AC out must be at
case ground. I looked at some of the lower cost ( WAGAN sinewave) and others
inverters, and their so called natural was floating above ground as part of
the sinewave. The reason is that when I hooked these inverters up to my
camping trailer that normally plugs into the camping site AC power the AC
line going to the Camper is hooked up as it should be, natural and ground is
hooked to camper ground as required by code. I used this to power the small
AC lights and other devices plugged into the inside AC sockets running from
the Trucks DC battery supply. Now here is the problem that is very
DANGEROUS, and should be looked into. From the cheaper modified sine wave
or puresinewave inverters from many of manufactures, the NATURAL side of the
AC out is HOT ( part of the waveform to save a small cost in building) , the
problem is that if someone touches the truck, and the camper next to it
guess what BAD SHOCK. Keep this in mind if you are hooking the inverter to
something wired external. Some of the Xantrex Modified Sine Wave Inverters
,Prowatt,and Portawattz and their Prosine series,have this with grounded
natural output, and EXELTECK seem to also has a good grounded AC natural
with a clean sinewave output. I do not know about Samlex sinewave series but
I am looking for more input.
