The Exeltech was my original choice, but the 100 watt load is a bit too
close to the rating for an inverter in an uncooled location. Exeltech
tech support recommended the 250, but the inverter was pushing 1/4 of
the total budget per unit, so the customer asked if I could reduce the cost.
I found that computer supplies do just fine on mod-square wave. (Dan's
right, let's get past the old Trace hype and call this waveform what it
really is)
Also thanks for all the replies; great info as always. I just haven't
heard if anyone has tried AIMs inverters. They make transformer based
units as well, but I know nothing about them which spells trouble in
this industry.

How about the Exeltech XP125?
We have used a few of those and of course many of the Morningstar units.
Thank you,

Hi Guys;
I have a project that will need multiple small battery based inverters. Each
one will only be running a 100 w max. computer power supply, so there are no
significant surges, and modsine will be fine (most small UPS systems only put
out modsine) Avg load will be 20 watts.
I know these little devils are sold everywhere from Walmart to Autozone, but
what brand holds up to moderate use?
Has anybody tried AIMs inverters?
Cost is an issue, budget can't afford a Magnum 600, or other transformer based
model, but reliability is most important. I'm planning on oversizing it
substantially, I figure I would start with something at at least 400 w cont
rating, just to make sure. I had an old no name 1500 w inverter on our work
truck that we took in on trade, and it actually ran a circular saw. We tried
to burn it out and never did.
UL listing is not an issue, as these will be very small stand alone systems not
requiring AHJs or permits.
Thanks in advance as always,
