SOLAR
I am going to put solar on and I was looking to get this http://www.renogy-store.com/200W-12V-Monocrystalline-Premium-Kit-p/kit-premium200d.htm with a 40A MPPT controller or the 300W setup up to 400W....

I have 2 group 27 batteries( I think they are 80ah ea.) they are both new as I have only owned this since July. I only need the MW for warming up food one the road between destinations. I was told by a solar comp that I could get by with 300w and to use a MPPT. If I am missing something then please help. Thanks
MW's need a lot of power, more than a couple 80ah batteries or solar can provide (for very long). As I said earlier, 4 GC's is about minimum so that you don't get a huge drop in voltage causing your inverter to shut down.
I'm not sure what the solar company understood as your question to answer it like that, but you cannot "run" a 1200w MW oven with 300w of solar. If an appliance needs 1200w, you must feed it that. It would be possible to run it at high noon on a clear cold day with at least 1200w of panels. Your 2 batteries would help, some.
Solar is not a generator for instant power. It's a slow, all-day process to replenish the power you used from your batteries to run the microwave and toaster.
