A bit more on inverters and generators--
Most lower priced non-inverter generators produce 60 cycle AC current directly
by turning at a very specific speed. This means the engine on a
non-inverter genny must run at full speed all the time- even if there is nothing connected to it. This makes more noise and burns more fuel.
Some higher priced inverter generators produce DC current which is
electronically inverted to 60 cycle AC power.
This means the engine does not have to run at a specific speed.
For this reason when the generator is under light load the engine can run
at a lower speed. This is often quieter and more fuel efficient.
NOTE: Honda calls this eco mode or something. I'm not sure that all
inverter gennys have the low speed under light load option so you might
want to check before you purchase one.
Also these more expensive inverter gennys typically have better mufflers.
They are pretty quiet but I disagree with folks who say they can't hear
them run!! I CAN HEAR A HONDA from across the road no problem!
They ARE quieter than most others tho.....
Finally, some campgrounds don't allow generators during certain hours.
Even the quiet ones are not allowed in some areas.
Hope this helps a bit!
and happy camping!
