Battery and power inverter grounding

klane

i currently have my ground hooked up to the neg terminal of my battery bank. Do I also need to hook the ground directly to the Neg on my power inverter as well or will the one conection suffice? I realize I need to ground the metal caseing for my power inverter to the ground but not sure as far as the inverter electrical system.

Thanks in advance!
