[RE-wrenches] Reliable Cheap Modsine Inverter

[bob ellison]

I can second the Morningstar SureSine, it just works! To bad it is not
available in 24 volts. I keep hoping.

Ray;

Keep in mind that with truck stop inverters, everything *must* be plugged
into the front 120vac outlets on the inverter. You can use a power strip,
but can NOT run a wire to a breaker box. The ground/neutral bond will fry
most of these inverters, and you could see some significant leakage on the
ground line.

The only brand I've had decent luck with is Xantrex ProWatt. The rest have
all fried fairly quickly for various reasons.

Personally I'd go straight for a MorningStar SureSine, and a small breaker
box. These are awesome little inverters at 300W continuous. No fan, no
hassle, they just sit there and work, for years.
