Use no thinner than 4 gauge wire for positive, preferred 2 gauge or thicker. Make sure it's fused at the battery.
Use 4 gauge or thicker (2 gauge preffered# negative wire. Make sure it's grounded to CHASSIS.
NEVER rung long runs of negative wire from inverter back to the battery. This restricts current flow!
All your devices/systems, including premium sound system in every vehicle is always grounded to the chassis.
This reduced unnecessary electrical noise, and also makes sure maximum current transfer.
Current flows from Negative to Positive, not the other way around. #Positive attracts, Negative repells#
This is why short runs of ground wire, attached to solid part of the chassis, will allow the best electron delivery (current).
Try to keep negative wire under 24 inches.

Yes. The 3000 watt unit can be attached to this vehicle. The vehicle can be running while it is operation. If the vehicle is running and a low voltage or over voltage alarm comes up, the alternator voltage regulator will need to be adjusted (Very rare). You will want to use two positive and two negative 4 gauge cables with the ring terminal ends (Pass a bolt through them to secure them tightly). These are available at Canadian Tire stores in the automotive section. Connect both positive cables to positive of battery #1. Connect both negative cables to negative of battery #1. Do not use a chassis ground.
