Would you connect the (-) 12 V of a solar system to the ground or the Neutral?

When building an off-grid solar system, which can be used as backup for your home,:

- Would you connect the (-) 12 V of the battery to the ground or to the neutral, or keep it floating?

- Also would you connect the (-) wire of the solar panels to the ground or the neutral, or keep it floating?

I am assuming that the output of the inverter is floating (no neutral pin)
and the ground output pin of the inverter is connected to the chassis of the inverter.

Also the (-) 12 V input of the inverter would be not connected to the chassis of the inverter.

Never ever ever neutral.

You'll have a bad day if you do that.

If anything you can connect that to ground, but that depends on the documentation for your equipment. So read it.

Thank you for your reply.

This makes sense since the neutral carries some current,
so unless there is some kind of GFCI protection, your body could divert some current to the ground.
