Ah, Don, you're probably a good person to ask.... Can you please explain inverters?
An inverter changes DC to AC. Most often that is from 12 VDC to 120 VAC. There are several types of inverters from motor generators to solid state. Modern solid state inverters are small and relatively efficient. They come in two flavors, modified sine wave and pure sine wave. The wave form of a modified sine wave is a step from 0 to
around 70 volts then a step to around 140 then back to 70 then 0
then repeat the cycle to negative values. Pure sine wave is just
that, like comes from the grid though there may be noise on the line.
Most applications do well with MSW but some printers and TVs do not
like the noise. Microwaves and other devices that depend on peak
power do not work as well on MSW.
I like several small inverters rather than one large one. There is a
reduced overhead and I can tailor the loads as needed. I nave 175, 200, and 400 Watt inverters but the 175 is the most often used. I have recorded the wave forms and hope to get an article up one of these days.
