Inverter battery ?

My Prosine 1800 would run that 1000w heater no trouble at all.
4x GC2 connected with 4/0 (not #4) wire.

I think a Xantrex Prowatt 2000 would serve you better than the roadpro.

+1 for using propane if you can.

Running the engine will always help but will depend on the alternator output that could be low at idle and the wire connection to the battery.

Do you know if running the engine while I cooked would allow me to use just the 2 golf cart batterys?

Too much of a load on the alternator besides given the voltage drop from alternator to batteries won't put much of a dent in the microwave usage.

Better off getting a single burner propane stove. I have one and it works great. Or, buy a generator.

I need to power this single 1000watt range , My system currently is made up of 2-------6volt golf cart batterys ,,,,, What size invertor do you recommend and should I add batterys or change to different type of batterys

First off, you'll likely find a pair of GC and 1000W is pretty marginal with an inverter. GC voltage drop at that current gets to be to much with only a pair of GC batteries. When I was trying to get 1000W from a PSW inverter, a pair of GC had to be at least 75% SOC during the entire time to avoid going into low voltage shutdown.

4 GC solved the problem, now I can drive a 1000W load down to 50% or lower SOC. (How much lower, don't know haven't tried, but at 50% everything was humming away)

you can either add another pair of GC or hook the inverter up to a pair of 12V batteries, run everything else off the GC. BFL does this and it works well for him. 12V batteries typically have much lower internal resistance, couple with a pair, so each battery only supplies 1/2 the current and it's a winner.

Lastly, personally I don't think your going to be very satisifed anyway. running a microwave for a few minutes, hair dryer for a few minutes works fine. A burner element???? How long do you want to run it before recharging batteries?? 15 minutes?? 30 minutes??? 1 hr??? At 1000W (90A) you'll take a pair of GC batteries down to 50% of capacity in around an hour. Likewise with a pair of 12V .

Use batteries only for the things you can't do with propane or use the handy honda 2000.
