Re: (ET) Rotary Inverter

Brad and others,
    The efficiency of this particular rotary inverter doesn't impress me.
If you draw 90 amps with a 28 VDC source to produce 1500 watts, the
efficiency is 100  % x (1500 W / (28 V x 90 A)) = 59.5 %.  I'm hoping the 
90
amps is an inrush current, otherwise this unit is very wasteful.

Thanks.
