Tesla, making it easy to go off grid

The price seems OK because you and I helped pay for it. Between Tesla, Space-X and Solar City Elon Musk has taken $4.9B of our tax dollars. He always works in areas with lots of .gov money available. To wrap your brain around the amount, picture a stack of bills making 1million dollars. Now try to picture 4,900 of those stacks. All out of our pockets.
 
Power: 2kW continuous, 3.3kW peak.

So a 10kWh unit can output full load for... 5 hours.

That's not a high output.

The average US household uses 900+kWh per month. You'd need to have a bunch of these, not just one.

Also, what happens when your house burns down because your "battery wall" self immolated? Is Tesla going to rebuild it for you?

I agree completely with your assessment but who really runs at peak if the grid goes down? No one. So realistically speaking you could easily double that 5 hour figure. The real breakthrough with this is the size, price and weight of the battery pack. I would definitely buy one of the 10kWh units for an off grid cabin. A few panels and an inverter would make a nice system. You should see my battery house for my place in Texas.... Ugly! The six 6 volt golf cart batteries weight 230 lbs each and I need a bunch of them just to give me basic electricity in the cabin.

Do the math 10 KWH for $3500.

A 120 amp hour marine battery is 1.44 KWH (@20hr discharge rate) you can get one for $80. 7 deep cycle marine batteries will store a bit over 10 KWH, and you can buy them for $560 total.

$560 vs $3500 what a great deal!

Any time I see news headlines with "Tesla" it makes me cringe.
 
they made it even easier to get off the grid with their new $130k electric suv which you can charge off your new battery pack.

Agreed. Whats the service life on the marine deep cycle? About 5 years?
 
It's a great step in furthering the technology, but not good enough for the common man.

Personally, I'd like to see the neighborhood nuclear reactors take off :D Build a community, drop one it, and survive anything!
 
Don't get me wrong, I think shrinking the footprint and the wall mount option is awesome. I just need more kWk/$ than that. Especially if they're only saying 10 years on lifespan.

Not to mention, it's unclear whether Tesla will even survive 10 more years.
