Best 2000+ Pure sine inverter at This time

Yes, the more flow the better..

 

The issue is heat. Running too much power through a cable that is too small can cause a fire.

 

I understand that my point is by using bigger battery cables you have more Amps (flow)and in turn less heat..

 

I'll argue this point...LoL
You're not going to have MORE amperage, you're going to have a greater capacity to carry that amperage. It's like running water through a hose. You can (eventually) put out a house fire with a garden hose but you're going to get hella hot doing so. With a 3" diameter hose you're going to stay cooler while having the capability to run the capacity to put the fire out.

 

The problem with too thin cables, aside from a fire, is potential voltage drop causing higher amperage loads which could overload the inverter. Only really a problem at high loads and if the truck isn't running.

 

Yes, but because I had bought it a while I was rebuilding he the truck I was out of warrenty by the time it blew.

Im running 1 awt (welding cable type stuff) through a 250 watt circuit breaker, 2 gauge would be way too small

 

I have an AIMS 2500 pure sine wave. I think I got it on Amazon a couple years ago, around $400. It's the best one I've ever had and I've had lots of them. It handles everything I throw at it.

Buy quality cable the right size and use big ANL fuse or breaker between batteries and inverter. Very important. I think I have a 250 or 300 amp ANL fuse.

 

Do you have any pictures?
