MASTER THREAD: Powering house or other things with Model 3 12V battery

[PianoAl]

And here's the permanent arrangement in the garage:

My Fiance and I put together a video this afternoon showing how we've been able to use our Model 3 as a makeshift generator to power our woodstove blower, computers, internet router, and cell phones during natural disasters and/or power outages. This method made all of the difference for us through the 2019 Blizzard and horrendous 2020 wildfire season.

Please feel free to share with anyone who could benefit from it. We made it with all of the folks across the southern US without power right now in mind.

cool I came here with this https://www.cnbc.com/2021/02/18/som...hybrids-to-power-homes-amid-winter-storm.html and hoping TSLA will do something similar.

This is the type of system that I am considering to build,
to run my refrigerator during the day while charging the battery at night using ToU rate.

? Seems like a ridiculous waste of time and money and risk to your $50K+ car to shift load for a few pennies per day (what a fridge costs to run).

Seems like a real waste of an opportunity, almost negligent, for Tesla not to allow this during emergencies. If you could run your gas furnace fan with a Tesla that could make a huge difference for some people. Most Tesla's have like 10x the energy as that Ford.

I think you looked a a different thread.

On this picture, @PianoAl was using an AGM batterie and an Inverter, not the Tesla battery.

My fridge uses between 1 kWh and 1.7 kWh a day, depending of the thermostat setting.
Off peak kWh is about $0.12 and peak kWh is about $0.30 in winter and $0.50 in summer.

So it's not too much about saving some dough, but to have a back up ready for my fridge and some lighting in case of outage.
And also to play with inverters to start building a small out of grid local system using solar panels and/or wind meal.

Was responding directly to you, in this thread, with the knowledge of the components listed.

If you like tinkering, fine, but transferring load from day to night for a fridge is a science project and not a practical use of any of the components listed. It certainly will lose you money, it will not be possible even with a few hundred $ spent to "save" on load shifting for the meagre amount of electricity a fridge uses.

FYI . I have a (non-Tesla) whole home battery and solar system with fully spec'd separate backup loads panel, transfer switch, thousands upon thousands for the components and install, and I surely didn't put that in to save money. People shouldn't "play" unless they understand the electrical code requirements and specifications are there to save lives.
