I met a family in Kingman,Arizona which lived off the grid,on 12-VDC,and 120-VDC power.
They had a rather large,home-built 120-VDC wind generator which they used to charge a series-connected group of batteries.
Some of their lights and appliances were 12-VDC,and all the shop power tools had brush-type 120-V motors.
They were mentioned in the newspaper after a storm had knocked out the city's power,and this family's home was the only one 'lit up'.
If a photovoltaic array were located such that there couldn't be any stray shading,the series connecting wouldn't be a problem.
Converting a voltage from DC to AC would require some type of oscillator to produce the 50-or 60 Hertz necessary,and some sort of power conditioning to create a sine wave (motors need this especially).A square-wave and some synthesized sine-wave inverters will not produce an AC current of sufficient quality to run some ac motors.  |
The only people buying or still using square or modified sine wave just don't know what they are doing.
Pure sine inverters have come down a lot in price recently. I remember when they were over $1 per watt, now you get name brand ones for around 20 cents a watt.
Pure sine wave is all I use any more.
