Before you buy this system figure out how much power you would need in an emergency. If you have electric heat (live in the south) you can not run that system from this. You’ll have to use an electric space heaters and shelter in a small room. I think a space heater on high can use 12.5A or 1500w. If all you are worried about is a fridge, space heater, and a TV/PC you should be fine with a pure sine wave 12 Inverter that is 2500w those cost a lot less and can be installed by anyone. Your car can support around 1500w continuous. When you go over 1500 watts the 12V battery will go down and when you go under it will go back up. You are probably thinking… well that’s not enough but in my experience living in the Midwest on a cold day a space heater on medium will keep a small room nice and toasty. Your refrigerator only runs periodically and a small TV or PC use a few hundred watts. You just need to make sure the inverter you buy can run everything at the same time. Like I said if it’s all on at the same time and exceeds the amount of 12V your car can create then you’ll slowly drain the 12V battery.
I personally have 3 deep cycle 12V batteries as a buffer. This gives me plenty of time. My inverter cost $600 and does 4000w continuous 8000 peak.
I mounted it all to a small dolly I lay the seats back and get someone to help lift the dolly into the car and then hook it up. If you don’t think you need the extra batteries then you don’t need a dolly.
Tons of people do it the way I do it. It costs less and you don’t need an EV specialist to install anything.
