Outback sells UL listed inverters that provide power from the home battery system, allow the system battery to be charged from the grid when voltage gets low, sell power back into the grid when batteries are fully charged, and switch seamlessly back and forth between them depending on sunshine, wind, power use etc. The default is a fully charged battery which means that the owner usually has an immediate uninterrupted power supply for as long as the batteries hold up. (Our utility requires the UL listing in order to get permission to grid tie and sell back, along with plenty of paperwork such as a Certificate of Public Good etc. Our Outback inverter has been essentially flawless for many years) To get back to the Original Post, the Leaf battery has a possibility of being used to power the house and to be grid tied but an inverter would have to be custom ordered to run at the Leaf battery voltage or the battery cells would have to be re-configured to provide a voltage that the manufacturer supports.

In order to be capable of V2H you have to have a home energy system in place that allows you to utilize the bi-directional charging feature of your Nissan Leaf. An example of this would be the dcbel Home Energy Station: https://www.dcbel.energy/r16/. This Home Energy Station acts as a battery charger/inverter allowing your Leaf to power your home for days during an outage.

Hope this helps!

Ive been trying to get price and availability information for weeks but all I get is advertising emails. Why don't you provide some more details about your product since you said the "simple answer is yes!" How much is it? When will it be available nationwide? Everytime I type in a zipcode, it says the R16 isn't available in my area so I tried another dozen zipcodes from the southeast and they all give the same message. Is this product for real or just another pilot vaporware product only available in a few southern califoria zipcodes.
Sorry to hear about your frustration, we are sometimes frustrated too! Innovative R&D takes a long time and comes with lots of ups and downs, then adding multiple UL certifications to ensure the product is 100% safe and follows the multiple local and state wide regulations (that often differ from municipality to municipality) adds another level of complexity. Trust us when we say that no one wants this product in North Carolina more than we do!

In terms of pricing, the dcbel r16 starts at $4,999 USD and varies based on the number and type of EV connectors you select, along with your desired cable length and whether you wish to benefit from the blackout power feature. We are currently serving the state of California as well as select regions in NY and will be rolling out to additional regions over the course of 2022. Unfortunately, because energy is so local and the way utilities work varies from region to region, it is near impossible to roll out nationwide at once.

We understand that the EV market has been plagued by vaporware and failed product launches, but we promise you that in 2022 you'll learn that the dcbel r16 is different.

Which regions? Would you consider offering a less expensive, power to house only, version?

^^ +1 for this. Since I'm out using the car during the day, charging it DC to DC from my solar panels is not an appealing use case. I will always be L2 charging post midnight when my rates go down unless I have a battery wall solution one day. Meanwhile I could be interested in a V2H solution for emergency backup purposes.

Including the product page, in case anyone is interested:

Pricey, but sounds promising and more worthwhile if your electricity provider does time of use metering, so you can sell back to the grid at a profit. That would definitely help offset the cost of the unit.

Would be interesting to know the payback period for a typical California EV owner who uses their EV's pack to sell back to the grid on a daily basis.

Actually, looks like it's a solar charge controller and inverter too, with V2G capabilities too. So, $5k is pretty reasonable. 15kw output from the EV is decent too.

Very cool!

Maybe I'm missing the obvious here. What my solar panels generate already gets sold to the utility under the net-metering program. Installing this unit would not change anything on that front. Besides, charging the EV batteries first and then selling power out of EV back to grid means you are losing some % in the charge / discharge process as well as increasing your EV battery deterioration pace.

TOU metering can make power much more expensive at some times of day than others. The idea is to sell excess power back to the grid when it is expensive and then charge the batteries when power is cheap.

Here's an outfit that is doing this commercially. https://youtu.be/lMmH98KlSEo

Got it. Makes sense since most of the day's solar power is generated around the noon to 3-4 pm zone and the higher cost TOU kicks in at 4pm. I am not aware of difference in what the grid pays back to me based on TOU. I will research this a little more.

For industrial use I totally agree the approach makes lots of sense. For home use everyone's mileage will vary... My car is usually away from home during the peak solar hours so for me this would not work at all.

As I've said before here, almost everyone who wants one of these already has a charging station at home, while only a much smaller subset have a large solar array. This makes a simpler, less expensive unit with V2H only, for power outages, an appealing product. It doesn't need to be a different unit, it just needs to have fewer components.
