Proper ground is necessary on products requiring external connection. Siz eof the ground is based on the size of the unit.
300 watts would not require much over a #14 ground. Memeory says the ground is 12.5 % of the max rating of the device.
I would run a separate ground and not tap onto any existing grounds. Those grounds would (should) have been calculated on the loads originally connected.
Thanks. I presume you are referring to the ground connection on the inverter, and not the ground for the 30A female RV receptacle. For the ground connection on the Morningstar inverter, the manual suggests 4 gauge minimum. That's what I used.
