Lithium-ion battery pack prices hit record low (opens in new tab)

One opposing force to this eventuality is the huge and still-growing RV/camper/boat industry, which has begun shipping some really good, house-sized DC electric appliances lately. It seems like these worlds might one day converge.

> Many areas it is illegal to not be connected to the grid

It’s mind-boggling that this happened as it only seems to serve the private power companies while simultaneously restricting entire populations from some of the biggest benefits of current and future sustainable energy sources.

In some places it's also illegal to have that many LI batteries in your house (looking at you, SF).

Saving money. If it is cheaper to generate your own power, a lot of people are going to do it. Practically speaking, you would probably still need (and pay for) a connection to the grid but just not need to use it. This isn't a reject society and live alone in the woods kind of appeal. You are going to be spending money on power for the foreseeable future, why not minimize that expense if you can?

Also in developing countries where there isn't a reliable power grid, would you just skip that step entirely? I know some places in Nepal where they have daily rolling blackouts and it is extremely annoying.

30kWh for $8k here

I'm not sure if I would classify that as a home battery, but it does indeed seem much more reasonably priced. I don't know if I can find a local installer selling this or anything else in the same price/kWh category.

With inverters and solar panels I don't have this problem.
