Ah ok I thought you were referring to the Kia/Hyundai V2L implementation. That is definitely only 120V in the US.

You are correct, the EV trucks have 240V outlets which could also easily charge the battery through the chargeverter (or even direct to the inverter generator input). And they certainly output more power. It's interesting to compare the cost of 100kWh of vehicle battery (that is useful as a vehicle) for $70k and 100kWh of LFP home batteries for $30k-$60k.

If you diy those batteries you could build a 48V 280Ah battery (cells+bms) for ~$1500, say 7 of those for 98kWh for $10500. That said when compared to commercial lfp batteries a large ev battery can be tempting.

Yeah, I don't know anything about the little EV cars.
But that makes sense, I guess.

You are correct, the EV trucks have 240V outlets which could also easily charge the battery through the chargeverter (or even direct to the inverter generator input). And they certainly output more power.

They also have dedicated systems for V2H and V2G.
For example the Ford Lightning Home Integration System.
Includes a bidirectional charger, and everything for a hybrid solar system. (Inverter, transfer switch, stationary battery, SCC and PV)
I wouldn't consider it as a good value, but they do offer it.

It's interesting to compare the cost of 100kWh of vehicle battery (that is useful as a vehicle) for $70k and 100kWh of LFP home batteries for $30k-$60k.

For me it makes the EV worth the cost.
In combination with a solar system (cheap fuel) , the extra battery storage is very cost-effective.

Here's something at the low end of your "LFP home batteries" price range:

You can buy a BYD EV in China or less than we pay for same amount of BYD batteries.

A BYD car in China is priced less than the same capacity BYD battery alone in the US.

Is China really subsidizing the Chinese and US market so heavily?
Overall, China has become an economic powerhouse, selling things that middlemen mark up several times over before we buy it.

BYD Yuan UP launched in China, price starts at 13,400 USD

BYD Yuan UP comes in three models

45 kWh US $16k
That's 1.5x of what we would bay for EG4 PowerPro battery, 75% what we would pay for BYD battery. And it comes with a car.

I'm more than a little concerned about something from the lowest bidder up against my home, in case it decides to burn down.

Just came across your thread. Nice install.

Check with Midnite. It is my understanding that The One includes SPDs on the PV inputs, so you only need put SPDs out at the mount (if you so choose). Not sure about the Batt or AC lines, they may be protected as well.
