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.
