[RE-wrenches] Reliable Cheap Modsine Inverter

[Larry Crutcher, Starlight Solar Power Systems]

Hi Ray,

Since you have no budget for sine wave, the best, low cost modified square wave we have sold is the GoPower GP-300W. We sell it in our retail store for $39.

Actually that statement needs to be qualified; the BEST mod. square wave inverter we have ever sold/installed was the Powerstar 1300. It could EASILY start an RV roof air conditioner. Those were great inverters.

Thank you,

Larry Crutcher

P.S. You don't really believe there is such a thing as a "modified sine wave", do 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,
