I'm writing this from my off grid shack.

I have 15kwh of lifepo, and even if it weren't hooked to 4kw of solar I could still run my fridge, charge my phone, and run the fan in my fireplace for 4-6 days... longer if I dump the fridge.

It's 6U of deep 19" rack space.

So 2 x that isn't an entire shed-sized battery.

Though I'd happily have a shed-sized battery... I suspect that delivering and covering something that size would cost more than the batteries I already have, though.

If the GP commenter is typing in from the UK .. that's a not uncommon garden tool shed size.

By contrast modern Australian farm sheds have clouds forming within them and host birds that seasonally migrate from one side to the other.

They make hyper-insulated refrigerators for use on ships with limited electricity that use either vacuum insulated panels or aerogel insulation.
