New Inverter Charger, wiring question
I just installed a new inverter/charger with an automatic transfer switch and it appears to be working properly but I am confused on the ground wiring and want to make sure I don't have a problem down...

I too am installing an inverter(1500 watt, no charger).
my directions say to use the same gauge wire to run the ground for the unit, as used for the dc input wiring. In my case that's 1/0 wire min.
yet they expect me to connect it thru a mere 10-32 terminal. really ???
my input wiring, positive and neg, connect thru a 5/16 stud.
unit is a intertek (nature power).
Worse situation here.
My 1000W inverter instructions make zero reference to chassis ground. Not in the diagrams or the text.
But on the case there is a tiny 5/32" bolt that looks like it could be the inverter's case ground and is connected according to my ohmmeter to the inverter's AC output ground, which in turn is connected to the chassis via the permanent 12ga AC line leaving the inverter.
Is this case ground to Inverter AC ground to chassis ground sufficient?
Attaching a 12ga or bigger cable to that tiny 5/32" bolt just doesn't seem right.
