| Nov 3, 2016 at 8:26 | comment | added | Janka | @samcorcos: the customers Elon Musk wants to win are those who think they can buy the future today with the pityful little money they have. It's all about creating the illusion of being rich enough to buy space-age technology. At the same time, the same people espect things to just work, so Musk cannot use anything technologically advanced. Because that stuff still needs a team of engineers nearby to have it run. You cannot be at the top of the world with a consumer product. That's a contradiction in itself. | |
| Nov 3, 2016 at 3:11 | comment | added | Chet | I'm not sure what the "inverter" is -- but theres a transformer to turn 120V into 12V to power the lights and all the regular car stuff. And then there is a motor controller that turns the 120V DC into 3-phase AC to power the motor. | |

| Nov 3, 2016 at 3:09 | comment | added | Chet | you could have just asked me ;) a couple corrections: 20 batteries making a 120V circuit. And a 200 amp fuse -- which is a lot, especially at 120V. Power = Amps * Volts^2. More info here: chetcorcos.com/projects/2008/09/01/electric-truck.html | |

| Nov 3, 2016 at 2:21 | comment | added | samcorcos | @FakeMoustache haha I certainly believe that's the case, but they don't make those batteries available for consumers. I certainly don't intend to buy a $100k Tesla just to strip out the batteries ;) | |
| Nov 3, 2016 at 2:21 | comment | added | samcorcos | @pjc50 Interesting, that's good to know. It looks like these inverters cost ~$1000. Is that normal? Is that what a speed controller would cost? | |
| Nov 3, 2016 at 2:20 | comment | added | samcorcos | @Janka Thank you! That's the conversion I was missing. Curious, I had assumed that the Powerwall would have more storage capacity than 24 oldschool lead-acid batteries | |

| Nov 1, 2016 at 20:52 | comment | added | Bimpelrekkie | as it's possible that a similar type of battery might become available for use in cars Uhm, I'm quite sure the Teslas I see driving around here and there do not use Lead-Acid batteries, they use Lithium based batteries. | |
| Nov 1, 2016 at 20:51 | comment | added | pjc50 | The inverter converts battery DC to house AC. You'd need a different system - a speed controller. | |

| Nov 1, 2016 at 20:49 | comment | added | Janka | 6V * 230 Ah == 1380 Wh == 1.38 kWh. *24 == 33 kWh. Anything more you need? | |
