V2G coming to Cybertruck soon

[Gigahorse]

It’s so frustrating. It’s been almost 2 years I have owned the truck and over a year since I got PowerShare installed. It just sits there. I recently wrote a [snail mail] letter to Tesla asking for an update. No response.

I ended up installing a generator interlock plug and have a 30' RV power cord that I can power my house with, but seriously Tesla, why do I have to plug it in like a cave man after swapping over and this setup is not a viable every day usage scenario.
V2H V2G is insanely easy for them to solve, and I have no idea why after 22 months that the PowerShare seems like a sales gimmick.

Literally 1% of CT owners
To have a 100kw battery without being able to use it from an energy company is crazy.
Tesla really needs to step it up on V2G V2H with this MASSIVE battery

I understand V2G needs to get rolled out by the utilities, but what's going on here with it not working for people when it comes to V2H? I've posted before on this thread, but will share again. In my case I first had the Powershare installed, but not hooked up to my solar. Have an old 400amp panel and it worked. I've had the truck provide power to the house a couple of times when SCE cut the electricity.

Fast forward to when I installed a 3rd array of solar panels on my roof. I specifically asked the installer to look into the option of running the solar to the Powershare instead of directly to the panel. Now, if the power cuts during the day, solar charges and the car power the house/charge the car.

Why can't this work for other people?

I don't need to have my cybertruck supply the grid. I want it to supply my house so that my solar setup provides all my power needs. I have 3 powerwall 3's that on sunny days reach 100% by midafternoon. I export surplus solar to the grid through TVA's VPP program that pays me a whopping 2 cent/khw. Living in Tennessee means I have cheaper electricity than most at a flat 11 cents/kwh with no changes in rate for time of day. Once the truck is charged I want to export excess solar and then use the truck through the night to power my house which is what I sized my solar plus powerwalls for.

One problem with V2G is scale. How many tesla owners are among a particular electrical utility's customers, vs total customers? And what percentage of those have Powershare? Unless this becomes a significant percentage of the total user base, it does little to nothing, to help the utility.

Between my powerwalls and truck, I can push 24kW to the grid. That'll power several average American houses. We don't have to hold the grid up on our own, just help ease the load while things spin up.

V2H and V2G
With a CT ~10 Power Walls means>
Gas Generator inverters gone
Home solar LiFePo battery banks gone.
Home Standby Generators gone
It gets better
<Power by the Hour Pay>
Soon
Power Companies will all be Paying for CT power storage and Paying for CT power use.
During grid high use Power Companies must pay for your CT storage and CT power, or the Power Companies must start up $$$ big money expensive supplemental power plants during high grid use.
<Power by the Hour Pay>
Your letting the Power Company have access to your CT ~10 Power Walls for 1-2 hours every day. Day in day out year after year. This will save the Power Companies $ millions.
and
Will completely pay off a CT in 4-5yrs.

Spot on. Most people are simply not understanding how complex this system is and how many boxes must be checked before it is ready for mass scale.

Almost every municipal utility company supports solar and battery exportation to the grid, V2G is the same as a battery bank.
The cybertruck should really open up a ton of energy options for homeowners.

1. No solar, no generator, but HUGE 100kwh battery backup
2. Solar with HUGE 100kwh battery backup
plus another 7 different combos

In Texas, this seems dumb. We have .more than enough energy. So you discharge your truck for ztesla to make $$ then have to recharge it to drive and pay more $$$.

lol no

During the hottest summer days, when the grid approaches capacity, my local utility provider will put out an alert, asking for reduced demand. This also happens on Ozone Action Days, where lowered usage would help with local air quality.

I get a discount for registering my smart thermostat with the utility, so that they can reduce my A/C usage at peak times (I can override it if needed). I did the same thing with the UWC, so they can reduce/disable EV charging during peak demand (I charge at night anyway).

V2G is not giving the utility permission to steal your electricity. No one would volunteer for a program that is net negative. I might do it, depending on how well it pays, but I'm wary of the extra degradation on my pack (and that's assuming it doesn't affect my warranty).

The answ

The only problem with that is that the UTILITIES get to control WHERE they get the power from! Right now we have 2 powerwall 3's (27 kWh's worth) and I would LOVE IT if SCE would buy the power from them, but they only do so during 'special' events, which boils down to 1 time per month from May through October via the Tesla Virtual Power Plant (VPP) we signed up for with our solar power system...
They (SCE, our utility) DOES buy our excess SOLAR power, but even though I have the PWs setup to SELL power until 9pm, it stops at around 6pm every day and PEAK time is 4-9pm, so we only get to sell them 2 hours worth of solar at 'peak' prices (55 cents per kWh)...

We could EASILY push power from he PWs out until 9pm (and then, once at 'off peak' pricing, switch back)...

In addition, we cannot charge up the PWs using 'the grid'... Must come from our Solar system... SCE doesn't allow charging them from the grid...

So, I think it's more about the UTILITIES controlling OUR power and batteries than anything else...

We had hoped we could use our solar AND battery system to 'sell at peak prices' and charge up at 'off peak' prices, but it's not 'allowed'... Otherwise, our meager 10.8 kWh system COULD make us about $100 a month or more instead of about $10 a month (plus we save about $500 vs our old power bills)... BUT at least we're at the point where our ANNUAL bill is basically 'free'... For now...

We are on NEM 2.0 (BTW) here in California... Where Power companies are Kings! NEM 2.0 basically means we get the same 'price' for power we generate as we do for using it... NEM 3.0 is WAY worse though, you only get about HALF as much... ie: you PAY 24 cents when you BUY power, but they only pay YOU 12 cents when THEY buy it from you... hardly worth it...

The answer is to move out of CA. We have no such problem on the east coast. I have solar and PW at homes in two states, MD and FL, one conservative, one liberal. Both allow selling power to the grid at avoidable cost at any time under net metering legislation.

"No offense but it sounds like some fucking commie gobbledygook."

 

[Cyberham]

So the concept goes like this:

During extreme power consumption or use the grid can Pull from vehicles hooked up that aren't in use and have plenty of charge, and recharge them when the demand lowers allowing for the entire grid to operate more efficiently thus reducing costs and helping stabilize the system.
If every ev car and house had this system the entire city would essentially have a giant battery bank at their disposal to mitigate high power draws or even blackouts etc

 

[Gaximus]

I want this for just my house. I have power share but need to kill the house power to enable it. There is no way to enable it without my power dying for a few seconds. I would love for my truck to take over anytime (or during a window) when the peak hits a specific value.

It doesn’t work for me with solar/generator either. So who DOES it work for?

Works for me, Enphase Solar, no powerwall batteries. Has given me whole home backup a couple times.

Well, we WILL eventually be moving from CA... But it's probably about 2-5 years out from now (hoping for 2!!)... CA really SUCKS when it comes to utilities and gas... Heck, the OUTRAGEOUS price of gas (still over $4.39 a gallon where I live) is the MAIN reason I bought our Model Y... It was a no brainer.. Saved me about $300 a month on 'gas' over the past 3 years and that's HUGE (about $11,000 in FUEL and about another $1200 in maintenance costs).

So, I wouldn't have 'saved' as much if I lived somewhere that gas is so cheap... hehe... But prices will only get HIGHER here... Heck, I was LUCKY to get in under NEM 2.0... Actual INSTALL for my system came about 9 months AFTER they switched to 3.0, but I already had all my approvals done...

But we're outta here sooner rather than later...

I am happy for you, truly. Someday I hope it will work for me too.
