ground info needed.

[uemjg]

I have a MCI-8 and wondered if the aluminum floor in the cargo bays was a good place to attach a ground wire from the inverter/charger?

[Len Silva]

The best way is to run the ground directly to the batteries.

[uemjg]

not sure i understand...

Yes, it's a fine place for a ground.  But the better way to go is to wire your inverter/charger directly to the batteries with cable for both the positive and negative main cables.  Use the chassis ground for very low current uses like lights, a radio, etc.

I would tend to find another location.   Being low, it is susceptible to moisture and corrosion, especially with different metals.

It really depends on what the ground is for.  If it is the negative connection to the batteries then you don't want to connect to the frame or any part of the bus.  some inverters like mine have a separate chassis ground.  I connected my chassis ground directly to the steel structure of the bus.

The info I'm requesting is for the ground on the inverter and NOT the negative side...I am currently using the cargo aluminum floor for the ground.

[Lin]

Not sure I understand.  It would be best for both the positive and the negative connections of an inverter to go directly to the battery.  I believe the instructions on mine even said that.  However, if you are talking merely about a ground for the casing of the inverter, the floor may be okay.

Are we sure the question isn't about the ground/earth on the inverter's output - ie. the AC....

he's talking about the chassis ground lug on the exterior of the inverter. The floor of the bay is fine.

The "case" ground is relative to the AC voltage of the inverter.
