Grounding battery and inverter
Hey y'all, I have a school bus conversion that is setup for solar with 4x 120watt panels going to a charge controller then to a pair of 12v @ 125 Ah batteries in parallel all connected to a 1500watt pure sine wave inverter. I've had this system since July and, honestly, never considered grounding until a few weeks ago (I know, not good). I have since disconnected the system to keep the batteries inside for the Winter and in thinking about redoing my setup, figured I should do it properly. The inverter instructions suggest grounding to chassis but I was wondering if I can connect the inverter ground and battery ground (which is connected to one of the negative terminals, correct?) to a grounding bus bar and then attach that to the chassis with a 6awg wire. Sorry if that's confusing. If you need clarification please let me know!
