Power Inverter

So, you are saying I should mount the power inverter near the batteries and run an extension cord from there ?

need about 12ft. of cable and the power inverter is 1500 watts

just my 5 cents, but try your hardest to get that 12ft down to 3-4 feet. use an extension cord on the AC side if you need more cable to reach the plug for the fridge.

the longer a low voltage DC cable is, the heavier gauge it should be, especially when talking inverters and compressor fridge, which have huge start-up current demands.

The fridge draws 6 amps

6 amps at 120 Vac is AT LEAST 60 amps at 12 Vdc

Any ampacity chart will tell you what wire size then.. 6 x 10=60 for the 12v side. Yeah there's a surge but like a car the wire you choose for 60 amps should be fine. Go larger if you feel better doing that. Ain't gonna hurt nuthin'.

Oops.. I erred in talking about 120v amps.. sorry. It's 60 amps!!

The important number is the amp draw of the refer. That's what the cables are sized to. Someone else will know.. I do not.
