Your 6v batteries are rated *each* at 300ah? Most I've ever seen is around 220.

Some here believe that 12v batteries are better for high-amp inverter applications. Perhaps some big 12s would be better.

2-6v batteries will be a struggle with a microwave.

For a 300ah rating each would have be 300ah. Connected in series the amperage doesn't double just the voltage.

If a 6v battery was rated at 300ah, 2 in series would make a 12v 300 ah battery. Conventional wisdom is to discharge only to 50% for better cycle life so in the end you would have a 12v 150ah usable amp hour capacity

Discharging at a .3C rate would be about 1200 watts which should be ok with a battery bank that size.
