Wind/Solar Electrics ???

You might start with a small bank of golf cart batteries from Sam's Club, and a refurbished inverter/charger from here

A Trace SW would be best, but you'd probably be happy with a DR. Use a Honda EU2000 for a charger to get started and as a backup later on. Add PV as your budget allows. Excellent info on home built wind turbines here

There's no problem paralleling solar and wind charge controllers. Include a proper system monitor like an E-Meter or TriMetric.

Our cottage is off grid 400W worth of solar panels provide florescent lighting plus enough left over to run a tv -satellite dish for an hour or more off the inverter. storage is 8 12v deep cycle batteries. To run power tools or the wringer washer I fire up the 2000w honda.

To paraphrase a classic George Carlin routine- "I'll tell you what 'modified sine wave' means-- no f*cking sine waves".

No. GG is the ignorant one again. MSW is professional EE talk.

I'd rather call it professional sales talk. It's not a modified sine wave, it's a modified square wave to approximate a sine wave, and in many cases, sufficiently close enough. We run our whole house on a MSW unit. Trace's DR series inverters were MSW.

nope, just normal sales folk. unfortunately, it became an industry term.

No doubt you are correct....

But a "modified sine wave" inverter is a way for someone to tell you that you are buying a device which doesn't put out a proper sine wave... rather one which consists of an approximate sinusoidal curve made up from square bits...

So it's not a modified sine wave, but rather a near sine wave with lots of edges... Inferior in every way (but price) to a real sine wave inverter...

I would label the boxes with a nice star shaped sticker "powerful harmonic sine waves".

Small point.

Why would anybody modify a sine wave?

When people try to sell a "Modified Sine wave" inverter they are either ignorant or shysters.

George Ghio

No, what is being marketed is a "Modified Square Wave" inverter.

The ignorant can be forgiven.

The shyster wants you to believe that you are buying a better inverter than it really is.

Buyer beware.

Hi Nick

MSW is a shysters sales pitch which misrepresents the product.

Sort of like some> Alan Adrian wrote:

I have nothing against the modified sq. wave inverters.

Misrepresenting a product is lying.

Nope, shysters or ignorant. The ignorant don't know any better and the shyster is a lier and a thief. No point doing business with either of them. "Modified Sq. Wave" is just that. Sine Wave is not stepped.

Both types of inverter have uses and can provide good service. But a lie is a lie.

George Ghio

Using industry-accepted terminology to describe a product does not constitute lying.

No point in doing business with the ignorant? Sounds like a good idea considering the following Ghioism....

You might correct your error by listing some popular "sine" wave inverters, and the number of steps in their "not stepped" waveforms.

A chirped-frequency, nanosecond-wide, random-amplitude pulse train is a modified sine wave.

although I find myself in agreement with george (very scary, especially after his recent voltage driven LED faux pas) that the moniker "Modified Sine Wave" is a misleading term, and should be changed to "Modified Square Wave" in order to more accurately reflect the technology, you seemed to have gotten under his skin a bit. Congrats.

It was never a "lie" except in your ignorant vernacular. And for an industry in "deep shit" it seems to be doing rather well overall.

Another unsupported claim by Mr. Hole Digger. But at least you've admitted in weasel-speak that some "sine" wave inverters *do* have stepped waveforms. Would you say that they're manufactured and sold by liars?

I take that to mean that you won't be providing any examples of sine wave inverters with stepless waveforms. What a shocker.

If only he'd stopped at making that point. But Judge Ghio had to pontificate about liars, ignorance, and shysters. He just never knows when to shut up. Anyway, the term is unlikely to ever be changed, and it's a pretty minor issue IMO.

It's sooooo easy, since he *always* defends his mistakes with more mistakes. The topper was "never wrong mate". Now *that's* funny. Apparently the weasel definition of "never" is "most of the time".
