Re: (ET) ET and a Redi-line inverter



A rotary inverter will generate a true sine wave, but the problem is the output voltage may be high, low, or vary with load. So it's possible it was going a bit too fast for the modern electronics on the super coffee maker.

Got a real simple one? Those work.

I’ve got a decades old Redi-line rotary inverter, 120V, 1000W, that I’ve used a few times with a car 
battery, for tools and lights, and it’s worked well.  Uprooted tree from a storm the other night pulled the 
electric service off the house wall, and wife wanted coffee in the morning so I ran an extension cord from the 
Redi-line—attached to the front 2 batteries of the ET—in to the kitchen and the coffee maker.  Power 
disconnect on the ET was off.  She turned on the coffee maker and I hear shrieking from the kitchen.  Strong smell 
of smoked electronics and the maker’s switch was fused open.

Actually measured the voltage where I hooked up the Redi-line and it measured 12V just 
like it should so I don’t think the ET was the problem.  I’ve been told 
that the Redi-line ac wave may have been too square, and that fried the switch.  Does 
that make sense?

Thanks.
