I have a lot of experience with inverters, being an electrician and also RV owner (in addition
to my Westy).

Full sine wave is needed for some electronic devices, including some TVs, Microwaves, etc.
Other stuff, like power tools, can use modified.

Output depends upon what you want to run.  Get one big enough for whatever you want to power.

Keep in mind that these EAT power.  Take the watts, divide by 12 volts, and thats how many amps
you will draw from your battery.  1200 watts is 100 amps.  600 watts is 50 amps.  Both will
actually be higher because of loss in the inverter.  They are not 100% efficient.  Notice that
the case is a heat sink.  That means BIG cables connecting it to the battery, and a
soon-to-be-dead battery as well.

I think they are only practical for small loads.  You are about to discover why motorhomes have
generators.

> Have a '90 Weekender and am starting to modify it for everything from camping to general
business use. Headlight relays and fog lamps are almost done. 2nd battery next project. Finding
a rear gray cabinet to fit behind the full width rear seat (that I can pick up in the
Connecticut area) has been pretty much fruitless so far. Anyways want to add a 110VAC inverter
for general use but have no idea what size or type to get.
