Current state of using an inverter to have a Bolt power a house ?

The easiest is still the 120v from the 12v dc battery limited to 1.5kw continuous draw. No v2g or v2h stuff exists for the bolt at the moment.

I've connected a solar inverter directly to the HV battery but haven't reversed the CAN messages I'd need to send or find the relay I'd need to manually power to sustain my connection from the HPDM..thus this method requires the car to be on.. and draws a hefty 1kw idle fee..

Your best bet is to wait a few years and see if one of the many v2g/v2h solutions that are coming will pan out... but even then don't expect them to be very cheap compared to your generator. I expect a minimum 5-10 thousand dollars for the first setups with 7kw type outputs.. (and probably high frequency inverters that wouldn't be suitable for your well pump/hvac without softstarts added. ) Thats if GM decides to share/allow it on the bolt.. which is highly unlikely in my opinion.

so 4 routes.
1. diy, become an electrical engineer and hack it together.
2. buy a f150 lightning(only vehicle on the market with decently high power v2h options)
3. wait a few years and buy another vehicle that supports what you want with a v2h solution you like.
4. cry. and use 120v for cheap on a few select appliances.

Personally I vote you choose 1 and teach us how to do it. I'm not selfish at all.
 
I don't think the car being on draws 1kw of power. I know it says 1kw, but when you turn the air conditioner on it still stays on 1kw. I figure the air conditioning is at minimum 500 watts and probably more like 800 watts. So the car is using anywhere from 200 to 500 watts to just simply be powered on.
Yeah I would like to try and figure out more accurate numbers on that stuff one day.
 
Here's what the lightning inverter install looks like:
quite a few features/limitations mentioned. like 9kw inverting from the truck accepts 4kw of solar... but doesn't charge the truck over dc. Sounds like the inverter supports a standalone battery storage system? like 48v? the pv inputs are interesting too, since there is 4 of them.. sounds like lower voltage pv open circuit support, which is disappointing.

Effectively 5 components..
Inverter
Transfer switch + auto transformer
12v battery (powers the transfer-switch+EVSE+inverter during power outage)
EVSE(CCS connector.. but doesn't charge via dc?)
breaker+box for evse disconnect(prolly only the ac side?)

weird stuff all in all..feels like a hodge podge of stuff jammed together. Give this a few years for this stuff to mature..
