What the max size inverter

So I have 2 six volt interstate golf cart batteries, 300w solar and a Samlex Controller. What is the max size sine wave inverter that could be installed? We don't watch TV, use microwave or really anything that uses 110v. I just would like to have some availability for 110v if absolutely necessary. To describe absolutely necessary:(if my wife needs to use the 110v grinder to make a special grind of coffee for her latte). Meaning, it would be a pretty short blast of usage.

thanks,

I have two 6v GC's and use a 2000w sine wave inverter. For good performance (for M/W oven or other heavy load) proper sizing of the battery cables is important. Depending on your needs (think future needs) I would not go any smaller than 2/0.

What is the rating on the grinder? Otherwise 1000w is a general max for two batteries but you could push 1500 or a little more for a short burst.

For $90 you can get a 500W and for $160 a 1000W PSW inverter. Unless you plan on putting in a home refer I probably would not even go PSW. 500W would do put usage tends to increase.
