I just bought a 400W inverter and it seems to work really well but I
started thinking about safety. I plan to use it on camping trips and
other outdoor remote activities and was wondering about Ground Fault
Protection.
It doesn't have GFI built in (making it very inexpensive) so I figure
I should get a GFI module to put between the inverter and the load.
The question I have is:
Can I expect a standard GFI unit to work correctly with the inverter?
This inverter generates the AC voltage via a "modified sine" output.
I put a scope on the inverter and there seems to be power output on
both sides of the outlet. It works out to a RMS of 110v.
If the GFI unit will be perfectly happy with this sort of power output
what about correct ground fault detection? There is vehicle ground
where the battery sits and then there is earth ground outside the
vehicle. These two grounds would be isolated by rubber tires. Would
a GFI detect a short to either of these grounds?
Thanks,
