Does anyone know why potek 3000w inverter comes two red and black battery cable?

Someone may have mentioned this, but even if a fuse is installed it must have a fuse on each of the red or black wires. If a short between ground occurs on the single red wire without a fuse you still have fire.

Can you use it with the engine off? If Yes how long will it take before it will kill my cars battery?

Hello if you plan on running this inverter with your car turned off I do this when I drive Uber and I'm sitting for long periods of time in the cold weather and I have a small little Lasko my heat running with about 200 Watts. I would get an a AGM m Optima battery these batteries hold more power and are more developed for running continuously without the car running. I have an Optima AGM battery and it works just fine much better than the regular car batteries you can get them at any parts store. The person that answered your question is spot-on there are many variables on what will run your battery down but if you plan on running this without the car running get an AGM battery thanks

Can the 4000w power entire 30A RV with truck engine running? Diesel, 2 batteries, big alternator

If the system is 12 volt. It could be 24volt. If so 24v inverters are available. 30 x 120v =3600watts. And 4000÷12=480amps plus at 12v it wouldn't likely be enough at full output. But who uses everything at once. I would add a deepcycle battery or two. 100ah or more each. And a battery isolator. That way with small loads you will have a few hours. Without engine running. And still have starting power. And still have the added batteries charged by the alternator. Rambling I know. Hope I helped

As others said, it's an inverter. But I did find that even with no load hooked to the inverter, it will drain a 50 A-h LiFePO4 battery in 2 days.
