Excellent explanation of the different technology’s, comparisons & fuel consumption explanations, Jesse. Really enjoy ur videos and presentations, ur a great teacher for the novice to experienced, thanks for ur great contributions here. Cheers
As you said (specific) fuel consumption is expressed as fuel mass/volume per energy produced. Usually we use g/kWh for internal combustion engines. In the presentation @11:00 kWh (energy) should be used as the denominator instead of kW (power). 1 kWh = 3.6 MJ.
Someone was telling me that inverter generators produce less power than standards generators because the AC is converted to DC then back to pure sine wave AC. He was forgetting some major points. Many inverter generators use rare earth magnets to create the Field in the alternator. The standard alternator generator has to Consume power to create an Electromagnetic field. How much power are we talking about? Take a 12v 100A alternator and energize the field and try to turn it, it will be hard and very cogged feeling. Convert that same alternator to permanent magnet and spinning it by hand you could make enough power to electrocute yourself. Look at the size of the Field wire on a standard alternator, it is fairly large for a reason. Also, if you know anything about electromagnets, you know they are power hogs and a continuous drain because the field doesn't persist after you terminate the power. The generator is consuming AMPS to maintain the field, a field in which it's cogged nature makes it even harder to generate power with, so you need a larger engine and more fuel.
Now that reminds me, you talked about the current fluctuation in a previous video relating to pure sine wave inverters vs modified SW inverters, with the modified inverter the current fluctuation is it same as a generator without an avr. And can a generator avr be connected to a modified sine wave inverter to produce 'pure sine wave current' or is it impossible?
An excellent question Iohann, thank you. Might it be that some of the terminology got mixed up during the learning process? Conventional generators can be considered to produce a pure sine wave, as opposed to square wave inverters which try to mimic the sine wave. If this does not answer your question yet, please feel free to respond or ask for additional clarification. The the following video on pure sine wave versus modified sine wave inverters might also be of interest: th-cam.com/video/6UWLno-B4PA/w-d-xo.html. Have fun!
It is all about how you're using it. Generators are used for many other reasons then just as emergency home backup to run your appliances. Hence why there are all types, shapes, sizes, etc.
Because they are cheap and sometimes you can get by with them on a limited basis. I had an 800w modified sine inverter in my SUV that would run my 1hp vacuum cleaner. The wave often doesn't matter when the power is going to be converted back to DC anyway.

God Bless you Prof...your method and style of dissemination of knowledge is fantastic..
It's my pleasure, thank for your message.

Thank you Evan, that is great to hear. Thank you for your message!
superb overview. just what i needed. I have a generator and inverter and was deciding which to sell. I think I will be keeping my inverter.
Glad it was helpful!

Very well presented my friend
Thanks Gavin, it is nice to hear you are enjoying the channel.

GOOD MORNING FRIENDS, PLEASE CAN SOMEONE TELL ME THE DIFFERENCE BETWEEN PV INVERTER AND BATTERY INVERTER
Why they still make square wave generators, and all modern devices needs shine wave,i can't understand that.
