Battery Car battery to Power inverter set up

[chippy818]

So I'm looking to connect my car's battery directly to a Pure Sine Wave 2000w power inverter So I can use it on job sites etc to power a microwave of above 1700 watts.

My question would be, Do I need to have a one-way fuse in my wire setup directly from the battery to the inverter? Or can it be safe to assume that the power inverter would have its own fuse for this purpose?

In addition, should I be connecting a ground wire directly to soil or would it be safe enough to connect to a conduit object that has any form of earth contact?

Thanks in advice.

Don’t bother, 3 to 5 min of microwaving will take a car battery from full to empty.
even if you can start your van afterwards, the duty cycle will write off the battery within a month.
