hey hey g'day

heres a hypothetical for all the electronic buffs out there, would it be possible to power an inverter off the d.c. side of the ol' $98 gmc gennie, specced at "14V" (mines actually a diesel, same crap different sticker). as i said just a hypothetical as i'm curious, if nothing else only to maybe get puresine out of the gennie instead of the filthy mod wave that comes from the 240V side of it. Im not going to indulge in the timeless argument of "why take a gennie" camping, each to their own...

Should be.

An "inverter" is a switch mode power supply and switch modes will usually accept some quite strange waveforms and voltages as their input. The DC output from my $98 GMC is a 100Hz full wave rectified with no smoothing and thus returns to 0V 100 times per second and it's possible some inverters may get upset by this but if they have been well designed they won't.

Yes it is , but not much point as they don't put out there 600w or whatever at 14v only around 100w to start with.

Easy and more efficent to clean up the 240v a bit by putting a standard light bulb across it.

If your really keen , one thing I did was to run one through a 1:1 mains transformer which provides isolation as well.
