Grounding an Inverter?
Sorry if this is silly, but I'm not that familiar with conventions of doing electrical work on a vehicle that uses the chassis as the negative conductive path. So, I'm installing an inverter in my 5t...

I have two AIMS Inverters mounted in almost the same location in my trailer setup. These are about about five feet away from my main BATTERY switch on my trailer tongue area.
I run both POS and NEG INVERTER cables to this point... The 1500WATT Inverter uses a 175AMP FUSE and the 600WATT Inverter use a 80AMP FUSE (ANL/AMG Type FUSES).
I ground my INVERTER frames using separate 12-inch or so solid HD bare copper runs thru the trailer floor using proper ground lugs to the trailer frame. Each INVERTER is grounded separately (Not using the same ground lug)
Experimenting with HAM RADIOs I get stronger INVERTER RFI signals by NOT running the short solid copper ground wire to the trailer frame.
The 120VAC POWER coming from INVERTERs is very active with alot of RFI BRRRRR type signals due to their high current 12VDC switching actions to produce the AC VOLTAGEs..
A very big nemeses for HAM RADIO guys wanting to operate on 80M and 40M HF frequency ranges...
