Hi James; The el cheapo's may not like a heavy inductive load, at any rate
I know this was a severe prob with the older modified sine wave (so called)
inverters and they'd retaliate by burning up themselves or washing
machines, or even eat the occasional laser printer for a light snack. Get
one with a guarantee, let the company pay for the experiment!!<g> Try Sam

the homepower people really know their way around on inverters, they've
used them all, tested them all - Hard!

Thank you Malcom.
We hooked up a scope to the Portawatz 1550---it draws a sort of
mashed-to -the side wave; but never made any sol with the inverter. I think
I will buy an el-cheapo full sine wave inverter rather than experiment on my
one Ultrapro's transformer. If someone had come up with reassurances I would
have given it a try.
Issue one: will it fry the tran. Issue two, what sort of sol will it make.

Subject: Re: CS>Running HVAC Generator on Modified Sine Wave inverter
Hi James;I've only used lvdc, but run my machine a current limited
mechanically stirred homemade - on two types of inverter and the grid. The
inverter types are the trace modified sine wave (actually it's a modified
squarewave) 2500 watt and a trace 2512 true sinewave inverter, again 2500
watt. No detectable difference by my crude methods. You might find it
interesting that the 2512 uses a ~4MHz low power signal and control circuit
to vary the number of steps used to construct the sinewave under various
load and phase conditions; I can see this 4MHz as hash on my scope. I
contacted xantrex - who bought trace - by email but received no reply. I
understand a phone call will get a much better response. I really doubt
much 4MHz power could make it through any neon or similar HV transformer.
Take care, Malcolm
