if you're doing a real generator install, which is what you should be doing if you're that concerned with your local grid, you get the electrician to wire up an "essentials" subsystem served by the generator when you flip the transfer switch that way you're not running extension cords out through the yard in what's probably inclement weather and you can do stuff like power a few specific outlets and run the fridge if you want without dragging it outta its nook and plugging it into a cord snaking in from a window

I forget which breaker it’s tied to but definitely one I didn’t expect, like the kitchen or something

in 2019 i had an electrician run a 50a line for charging but i'll have to get a 100a line for the lightning. no 80a charging, no vehicle to load. i hope the charger they provide at least has daisy-chain capabilities so i can split the power to another ev

If you own a lightning you may as well get the house wired up so you can provide power to the house, but I guess once you're at the point where you're involving an electrician I can see just buying a generator too. Although you're probably using your truck every day and keeping it maintained, it may be more convenient than a generator that you bought and then forgot about for years, but in a "I may die without power" situation I'd want a generator over a BEV. RE: that Tesla airbag, nothing I've seen involving Tesla showrooms / service centers makes me think I'd want to own a car that arrived like that. I actually wouldn't want any make of car that shipped out from a factory like that, but most cars that aren't built in a tent have some sort of QC. At least you'd know upon delivery that this is the car in which you'll likely die. *edit* I forgot to ask, was there a reason for the new steering yoke? Other than looking "cool" to people who've never driven a car? Like they must have said something about why it's better than a regular wheel.

I had a house where I'd lose power and it'd take SoCal Edison five to seven days to fix the power, and it seemed to happen every other year. Enough power for lights, a fridge, and a computer would have been a huge improvement. Although I'd probably stick with a motorcycle and a generator over a Lightning.

FrozenVent posted:your main breaker is rated >100 amp sustained? 100A @ 110V is only 11kW, which is equivalent to the smallest/cheapest grid hookup you can get here. but idk how american main breakers work, if it's counting 110V or 220V because of the weird split mains thing. around these parts the distribution is done with 400V threephase, so you have that into your breaker panel and then the smallest main breaker you can get is 16A, which means sqrt(3) * 400V * 16A which is just over 11kW. that's okay for many households, especially apartments, but in single family houses 20 and 25A main breakers are not uncommon. 35, 50 and 63A grid hookups are available too but are more exotic and expensive things and as such are much rarer.

lots of newer homes in north america use 240v split phase at 200a, and every line can only take up to 80% of the amps so a 50a line can only really do 40a. lots of small businesses and some apartment buildings here use 208v three phase so they have to make sure to get 200v appliances. edit: my 32a car charger at home charges my car at 7.6 kw, and that same one only gives me 6.6kw at work Nfcknblvbl fucked around with this message at 14:12 on Jun 23, 2021 |

Oh hey it's my niche The practical application of battery backup, given current consumer-level battery economics and a desire not to destroy your nameplate capacity or WILDLY oversize a typical system, is short term heavy use (like an hour or less of continuous heating/cooling) or long term light use (say, 2 days of power for controls systems). The real killer is if you're quick-cycling heavy motor loads (like, say, an oversized central A/C unit). If you plan on running heavy HVAC or motor loads for longer than a trivial amount of time, diesel generator is the way to go - it only depletes its fuel during use, can be easily refueled during an outage (this is the big one, honestly), and is usually just plain cheaper per kWh over the lifetime of the install. Just make sure you lock it down, they're pretty easy to steal under a certain size

for sure, and if someone buys a lightning hoping to use it as a long term backup, they'll find it's stupid as poo poo to drive 100 miles to the next town that has power only to deplete 1/3 of the pack by the time they get back home

The fun part about electricity is that there are probably a few dozen ways to guess your way into making something that works 99% of the time but very few ways to make it safe when something unexpected happens I once encountered a residential receptacle circuit installed to a 50A single-pole breaker. Works great until a fire starts in your walls

There is no sensible reason to utilize battery energy as any kind of mall ninja survival plan for when the power goes out. Any money you spend on that specific thought is absolute waste. It's a a Marketing gag to fill the quivers of internet fanboys with lovely non arguments. If your brain is limited to "house runs on electricity, car runs on electricity, therefore car power house" you have bigger issues to worry about than power outages. By the way a full tank of gas will idle a passenger vehicle for several days all while producing heat and limited power to keep a small family alive, whereas a BEV will be poo poo out of juice after the first chilly night. But if you are actually worried about danger and survival, the last bloody thing you do is get a vehicle that requires the operation of the most complex machine in human existence (a national power grid) in order to provide usefulness past being a brick with glass windows. The whole idea is so incredibly stupid and offensive to anyone who ever spend any amount of time in a distressed third world country/ war zone/ actual disaster area that I'm frankly out of reasonable words. Jamming a shorted battery up your rear end to keep you warm is like one level above the BEV powered house to be honest. Get a generator. Plumb away on a combustion engine to heat your house, get a bloody wood stove. Anything is a better suggestion than buying a Duracell with wheels to feel cool that you can Dad out for 4 hours if the power goes off before you are off worse than everybody with a combustion vehicle, who at least can still GTFO. And if you are really, really ,really worried about heat and power, there are modern wood carburetor engine generators available for relatively small coin that can keep your own woodland poo poo Box powered and heated indefinitely so long as you provide some motor oil.  50 kw electricity, 100 kw thermal. Runs on wood. Buying this and a used Toyota costs less than a Tesla. They are also more environmentally friendly. Combat Theory fucked around with this message at 17:12 on Jun 23, 2021 |
