Its a lithium-ion battery. The price is quite good and lithium batteries have a long life span. Plus, it will both store solar energy and serve as a backup power generator.

Tesla is redefining the home power generator market.

It would be great for emergencies. An ideal state would be one where you could charge this battery and use the power during personal peak times.

Sounds like one of Heinlein’s Shipstones. ;) I’ll be keeping a close eye on these, to see how they perform.

wouldn’t it make more sense if they sell these batteries with solar panels together instead of by itself. Its great having a backup supply, but if grid is down for weeks then you’ll need solar to recharge the battery

I can get 15kwh in quality deep-cycle 6v. lead-acid batteries for something like $2800.00...will these Li-ion batteries outlast properly charged/cared for lead-acid batteries?

Are there any charge controllers with proper setpoints for those lithium-ion batteries?

[familyop]

I could buy and install nearly four times the battery (including cables) for that much money with lead-acid batteries that will last eight to ten years (thick plates, great controller, module array sized properly). Battery capacity for PV solar systems is usually measured in amp-hours, by the way—not kilowatt-hours.

Patent baiting...

I noticed the last paragraph in the piece behind the link. Folks, don’t try air conditioning indoor space from a battery.

[The Duke]

So, fresh from having (re)inventied the golf cart Musk is now (re)inventing the deep-cycle battery?

[9thLife]

kewlish.

Hope they don't spontaneously erupt.

[SWAMPSNIPER]

[zzwhale]

what is the COST per KW.... and how long is the battery life
if economical it could boost the stock because the car sure wont...

[ProtectOurFreedom]

Is there enough lithium in the earth’s crust to satisfy these visions of Musk?

[PGalt]

Thanks to all posters.

The last real power outage we had lasted over 3 days. If it can't run a normal house for that long it's no use to me. My wife is dependent on an oxygen machine day and night. I have a gas generator right now.

Is there a tax credit (taxpayer subsidization) for this?

[theBuckwheat]

Diversifying the electric grid is a good idea but of all sources of power, photo PV cells have are uniquely vulnerable to instant and total destruction by an EMP. Every PV cell in line of sight of an EMP will be destroyed. There is no way to protect them. They are basically EMP antennas.

So, it is just plain imprudent to use PV solar for more than a few percent of our power generating capacity.

Tesla is redefining the home power generator market.

How is Tesla doing on the new type of car battery they've been working on? You know for the $30K 300 Mile car.
