can you integrate bidirectional charging electric vehicle into off grid solar plan

I plan to build an off grid 1200 sqf home in southern California.
It will be mainly solar with a back up generator.
Problem: I will have several motors/pumps that each will require 2 HP for my well.
Would it help to have EV with bidirectional charging to reduce amount of batteries required and to decrease use of generator in high demand times

I've only looked at the bidirectional support on the Ford F150. My conclusion is bidirectional support on the F150 is completely impractical. And I suspect it's the same on any other EV that supports exporting. The issue is the F150 exports high voltage DC for the full power export capability that is integrated into a home. That still has to be converted to AC by an inverter. But there isn't any industry standard at the moment for feeding HV DC into various brands of existing solar/battery inverters. So, Ford makes you buy what is essentially an HV inverter that is specific to the F150. And it's expensive. Net, it simply doesn't make any sense to use it due to cost IMO.

Then there is the issue that Ford took a standard F150 truck body, that is about as aerodynamic as a barn door, and put an electric drivetrain in it. Net, the 70-80mph highway ranges drops to something like 120 miles. Makes it completely impractical IMO for anything other than an around town vehicle.

The EV9’s full bidirectional platform will probably be out this calendar year, so you can evaluate a second impractical option.

Another one is seeing if someone hijacks Lucid’s DC to DC buddy charger. IIRC they have a box that can convince a Lucid to send power out to another EV as DC. This is somewhat impractical due to the cost of a lucid (but the EV is way more efficient than a Lightning)

Lucid V2V is AC up to 9.6 kW, using onboard charger as bidirectional inverter I suppose.

Plugout has a kit for Toyota hybrid/phev to charge 48v batteries directly.

Nevermind, they closed. Maybe used on ebay.

Thanks for the correction about the AC output. I think I got confused because it depends on Wunderbox which also has a HV-DC DC converter in it.

9.6kW @240 is pretty good for powering a house, just toss a neutral forming transformer on it

No, so here: https://insideevs.com/reviews/60251...t=The F-150 Lightning with,320 miles (515 km).

Absolutely.
EV's are big battery on wheels after all.

My next door neighbor made the mistake of buying one. Granted it's the standard range battery pack. The insideevs.com test did 2 things that make them not represent the real world. First, they actually drove at 70mph, and nobody actually drives 70 on a highway with a 70mph speed limit. And there is big difference in a not very aerodynamic EV between 70 and 79 or 80 mph people drive in the real world on a highway. 2nd, they ran the battery nearly all the way down starting from 100%. That's also not realistic in the real world, because it's not practical to find a charger stop exactly where you need it and it's also not good to charge the battery to 100% every day if you commute to work on the highway. Most people with EVs typically plan to charge at around 20% when on the highway.

Here's a Motortrend test showing more real world data. And this is for the Extended range battery, not the standard range.

Hahaha! I know, I drive a big EV brick everyday (1980 converted Vanagon).
65 mph for the win

I take it the 2miles/kwh is not a typo
