Re: Using the Leaf for power in a Blackout: MY "Leaf to Home"

The chassis ground should to to an earth ground ie buried pipe or copper rod driven in to the ground, not to the vehicle. A vehicle is not grounded since it has 4 nice insulating tires on each corner :)

That's why I found the instructions confusing. Would it be safe to run ground to a garage outlet's ground connection? Or could that be dangerous to line workers during an outage. Not much discussion of ground handling in this thread.
I noticed you're still working with polymers.

That is fine to connect to any real electrical ground, often metal conduit is easy access and should be grounded if it was installed correctly.

Just don't connect your inverters "hot" or "neutral" to any house electrical lines.

Make/model?

See section 4.4 of the user manual. What are you planning to power using the inverter? (Edit: and does it have a 2-wire or 3-wire plug?) I assume the DC side will be the 12V battery of your Leaf?

Does anyone own one of these inverters?

Thanks Wayne, but I read the manual before posting my inquiry. You're probably overestimating my level of comprehension :P

OK, the Go-Power gp-sw300 manual says that the following points are internally connected together in the inverter:

The inverter chassis
The 12V DC negative input
The 120V "neutral" output
The 120V ground pin
The extra grounding terminal

You can basically ignore the extra grounding terminal, I can think of only a few corner cases where it would be useful.
