I am shopping for and trying to size an inverter. I do not have wires or fuse yet as I do not know what size I will need.
Length of wire should be less than 3 feet each way. I do have some 2/0 welding cable, seems a bit much for a small inverter.
The wire size is OK if you have it. You will need a minimum of #2 AWG and a 150 amp fuse. I'd recommend a 1000W inverter, minimum, and a quality product, not a price leader that may not handle the surge of the fridge compressor.
You should also ask yourself if the price of losing a chest of food is worth the additional price of adequate battery capacity. You will need more capacity. I wouldn't rely on the vehicle charge line to charge batteries to 100 percent SOC. That means you may park with less-than-full battery. Hence, the loss of food.
