How big an inverter do you need to run a small microwave oven. I just got a Engel 45 qt fridge/freezer, and would like to heat up frozen dinners while I'm on the road.
Hi Medic 2000w inverter will produce 16.6A at 120V. The inverter probably has a 15A resetable breaker. At max amp the inverter will produce quite a lot of heat. DO NOT install it near anything flammable. I would not mount it in the engine compartment. The heat from the motor will effect the preformance of the inverter. You should use a minimum 2/0 cable. At 2000w 12v = 166.6A the cable is good for 185A. The 4000w is a short time peak wattage and the cable will handle it.

Go HERE for food heating options......without an inverter.
LOL. Complete with petroleum flavored BBQ sauce. Sorry no offence intended. Still laughing though.
No offense here............hahaha. When I was growing up I worked at a trucking company and I would ovehear the drivers talking about warming up dinner on their manifolds. I also remember seeing manifold recipe books at truck stops as well.......hahaha

As far as the manifold oven goes, here's one suggestion to strictly adhere to - DON'T heat up anchovie pizza! If you think skunks are bad.... My father did this when I was young and I seriously contemplated walking home, not to mention the stares from other vehicles!
A stock alternator only puts out around 125 amps. If you pull 2000 watts though your inverter, you're going to be pulling over 150 amps and will discharge your batteries pretty quick. Make sure you're not too far from home when you try it.
When I ran the satellite wires for my xm radio I went thru the plug where the clutch would of gone thru. Big plug more then enough room for what you need to do.
Medic 66, I'll only suggest you research it a little more. Do a google search on "amp hours". You'll find sites with info about using car batteries for power. With your truck running, you can probably pull 1000 watts (~75 amps) without any problem. If you pull 2000 watts (~150 amps) with your truck running, you might get up to an hour use before your batteries are too low. If your truck is not running and you pull 2000 watts, you'll probably damage your batteries and end up buying 2 new batteries.
FYI, the 99 PSD stock alternator is rated at 130 amps, but they say is really only outputs around 100 amps.
