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....

We have 420 Watts of solar panels and 480 AH of battery--4 GCs and a 2000 Watt PSW inverter. Our microwave draws 160 amps from the batteries when running through the inverter. We ONLY use it at most 2 minutes at a time and let the batteries recover a little. I would not use an electric toaster--cheap stovetop ones do a great job.
Many have told you that 2 group 27 batteries are inadequate an I agree. We used to have 4 group 24s and they were marginal. If there is room for 2 GSs it would work, but watch battery voltage as the microwave runs. 3 group 31 true deep cycle might be your best option if you have room.
As far as balanced wiring of 3 12 v batteries is concerned, positive at one end and negative at the other is pretty close and when you do you battery maintenance you could swap them around every three to six months. Balanced wiring is only of concern if high current present either in use or charging.
