The majors will NEVER compete directly with Tesla, it's far, far too late for them. They'll never give up their "ICE" technology, it's too late for them, besides, they aren't really interested, nor do they "get it" (or care to). Tesla's competition will come from a new upstart, that's what they...

too bad, so sad. seems like someone missed the TSLA express Elon is the most innovative person on the planet, right now. Builds Electric cars, better than anything else existing, better range & performance: check Deploys it's own DC fast charging network worldwide, to enable the cars to...

Umm, you might want to re-state that. He CAUSED the slide in the first place, by casually mentioning that China sales are way off in the 4th quarter.. If you're going to comment, at least know the facts,

Yeah, let me know when Tesla has ANY competition. GM's "Bolt" is not in the same class, and doesn't exist yet. Tesla has no competition to date.

Chris and Tony, you might want to reconsider developing an 80A EVSE cable. Tesla has just lowered the price of the High Power Wall Charger to $750 you could buy those and change the head to J-1772

offpist, I know you mentioned you didn't want to do this as a business, but if you keep getting salvaged Nissan packs, you could buy them, and safely take them apart, then offer the modules to the DIY community in your area, that want to duplicate the clever storage system you've built. you...

"offpist" stated he payed about $2K for the pack. i just watched one sell on eBay for about $2,300 used, so there is your used pack cost, with BMS and not deep discharging/overcharging it's likely to last a number of years

I believe the BMS is talking to the Sunny Island via the CAN bus, so it is aware of the SOC of the battery bank, and likely will not drain it down below a certain SOC/Voltage. There is a point of diminishing returns, there isn't much point in having a lot more KW of storage than what the PV...

you are correct, Sir. It's the same style cabling that Tesla uses on their UMC, there are (2) #12 AWG Red conductors, and (2) #12 AWG Black conductors, as well as a #12 Green ground, and 2 smaller #18 control wires (pilot, proximity), and a #20 wire as well (used to power the RF release, used...

Because you build it, you control the quality of the build, by picking higher quality components. OpenEVSE also fully implements the J-1772 standard, including the diode check (many commercial units don't even bother), and also implements the "ventilation required" check, though no modern EV...

regarding charging both Leafs, you could build/buy a "hydra" http://www.mynissanleaf.com/viewtopic.php?f=26&t=14012&hilit=Hydra" onclick="window.open(this.href);return false;

Sure can. If you wire up a 14-50 (which is the standard connector Tesla supplies with the Model S UMC), you will be "code compliant" for the 14-50 outlet, to pass inspection... Even though Tesla doesn't use the neutral, an RV could plug into it, and that does need a neutral.

EV charging is considered a "continuous load" (more than 3 hours). You are only supposed to draw %80 of the circuit breakers ampacity to avoid overheating the breaker and thermal tripping. 40A breaker, do not draw more than 32Amps. A 50A breaker, do not draw more than 40Amps. That is from...

The Assumption is that a 14-50, 50A outlet can be used as such, unless it is labeled as "40A MAX" If you plug in a Tesla UMC, and you don't turn down the charging current to 32A in the car, you will blow the breaker due to overheating. Worse, if you can't get to the panel, you won't be able to...

Typically on oversized box would be used, and you'd wire nut the #6 to #10 on the 2 hot conductors for your 30A outet, the ground conductor can be #10 for both the 30A and the 50A, you'd leave the #6 neutral capped with a wire nut. You can eventually change the outlet to a 14-50 (neutral...
