Ground need?
- Thread starter calstar
- Start date
Did RTFM several times(plus google) but no mention of this type of installation. Samlex sam-1500-12 inverter
I think the pic below refers to a situation where the inverter is tied in to the vehicle battery, but this isn't the case with my install.
Also states "negative DC input terminal on the inverter or the battery neg terminal on the battery itself is bonded to earth growing WHEN THE INVERTER IS USED ON LAND"(caps are as in manual)
I had a similar set up several years ago but don't remember grounding the inverter.

No ground required - it's not an inverter/charger and has no shore power input. That ground does nothing as regards the inverter.
There might be other reasons to tie the battery to the chassis, such as trying to minimize radio noise, but even then, it depends on the particular vehicle and radios...that connection to ground might make the noise worse instead of better.

The only reason you'd HAVE to ground it that sometimes is the bond for neutral to ground, and if you wired up a floating neutral behind a GFCI protected outlet it'd likely trip immediately because of the ground fault.. but it'd of had a chassis ground of its own.
It is safer to wire up the ground when you have it, say a short developed in the inverter and you touched the metal chassis you could be the path to ground, it'd give yeh a nice shock.. and as said, could help with RF interference.
Its not the end of the world to have a floating neutral, most gensets are.. and really the only thing they seem to mess with is GFCI stuff.
