Replacing Factory Inverter with Pure Sine Wave Inverter

This is interesting and I am not sure that I am convinced that it is true in general. Just thinking about making a stepped wave verses a continuous sine wave it seems that I could make the former with less loss. I am not saying it is wrong, I just need to learn more about the actual design, and even better see some real test data. It is unfortunate that the data sheet for the inverter that CCW bought only gives a maximum (peak) efficiency and not a curve or at least an efficiency at max load.


Also interesting that you use E for your voltage variable. Maybe that is a navy thing or you are even older than I am. I was taught that way by my dad when I was a kid, but by 1980 when I was inn college, we were taught that the convention was to use v.

Your thinking is very logical in that a square wave is easier to produce than a sine wave. Sinewaves generally have more circuitry to reduce the distortion. Reducing distortion is the number one reason for creating the sinewave for an inverter. A pure square wave as I'm sure you already know, has an infinite number of odd harmonics. Harmonics are not desired for this type of application due to the distortion they present. The harmonic content must be removed or converted (DSP or shaped) to reduce distortion. The modified steps are generally inadequate for a true conversion to a sine wave.

Distortion is very hard on sensitive electronic devices and most appliances. Resistive loads and some inductive loads (incandescent light bulbs as an example) don't care but will operate less efficient. It's not the making of the wave that is the problem, it's how that wave is used in the transfer function where the loss is at. (Efficiency)

I think Ford is doing themselves a disservice to not include sinewave inverters in their vehicles, they are truly better for today's electronics. You can search the internet for sine inverters vs. modified, I have found no advantage at all, properly installed. (Except a menial price difference in the manufacturing.)

I also found this to help describe why a sine wave converter is better than a modified square wave inverter. Ignore that it is an ad, just gives clarity on the type of equipment influenced for use.

Why is a Sine Wave Inverter a Better Choice than Square Wave?

If you are comparing between sine wave and square wave, then you are in the right place, here you know all the information which is best in both.

Here's another "simplified" description of harmonics and distortion using a spectrum analyzer. (Just like in school again.) :) I would imagine most sine generated signals utilize a DSP these days. (Digital Signal Processor)

Hope this helps, there are many facets of study on this, you could spend hours researching it.

They are related. We used "E" in school at times which stands for electromotive force. EMF = electromotive force = E. Voltage is sometimes referred to analogous to pressure, current to flow. E is the forcing function creating the voltage "pressure" since pressure is force/area. Mostly, as @Canyon Trekker provided they are used interchangeably, though, except for in academia where nomenclature gets scrutinized... That's my recollection at least...

😁 Ohm's law in graphic mode. Ohm is the resistance or load.

In my case it's that it didn't work with my laptop's charger. Despite it being well under 400W, it resulted in a whole bunch of clicking and some buzzing, with the laptop rapidly showing it was connected and disconnected from power.

I get the same when I plug in my MacBook Pro, which makes the OEM setup pretty useless to me other than charging maybe a drill battery or something.

Even a drill battery charger will struggle if it has any kind of control in it. After all this talk, a new inverter is going into my truck. I don't want to run into any surprises down the road.

That’s the spirit! Let me help with that addiction by recommending a Samlex.

I'll be doing the same at some point too.

Wtf do people even plug into the stock setup anyway?
 
Bringing back the dead to life: did this ever get anywhere?

I am now looking into replacing the factory inverter to a pure sine and possibly go bigger if room allows.

She's beautiful!

Pleasure to meet you; I will bring you home as well.

Thanks guys!

Best install I've seen. If you do this, follow suit, use big wire. @BroncoHooves , do you still have the wire for sale you once had? Might be a good fit for @AZsurveyor . 😁
 
I still have some more reading to do on the write-up but I have a good idea of what I need.

What I wasn't able to find was the same inverter; it seems as if though that model has been discontinued and the size was perfect for the space.

Love that bed plug for sure tho!

Still available :) https://www.amazon.com/gp/product/B08G5DQBV2/

The price is $70 lower than when I bought as well!
