From what I gather a microwave oven operates much more efficiently (less
power, faster cooking) running on pure sine wave. I understand there are
also some other types devices that either require or benefit from pure sine
wave power. In view of the premium price of pure sine wave inverters, I was
wondering if it's worth it or even necessary. For instance, if it used say
25% less battery capacity that would be important. Can anyone comment on
this and other considerations for selecting a pure vs. modified since wave
inverter for onboard use?
Thanks,
