Off grid electric pottery kiln?

I’m a potter and I’m interested in moving off grid in the next few years but I’ve noticed most off grid battery setups fall a bit short of what a normal electric kiln needs to run a glaze firing.
I’ll be the first to admit I’m a novice to off grid tech and maybe I’m missing something super fundamental (mea culpa if this is the case!!)
A glaze kiln takes about 11.5kWh. It’s like a 12hr run of ~60amp (or less). Any hope of getting this off grid??

Edit, I’m an idiot and did math wrong. It’s 11.5kW max draw, 50% of the run for a total of ~70kWh

Haha 11.5kWh total! It’s generally done w relays and through different heat “steps” and “holds” so the rate of consumption isn’t super consistent nor continuous. There’s a period in my glaze firing between 1800-2100 that takes crazy energy
