Starting to hook up a new system on my Northern Lite TC. I am a little confused as to what size wire to use between the batteries and inverter. I will have two 100ah LiFePo 12v batteries going to a 2000w inverter. When I reference Will's book it says that I can use 4 gauge wire if I keep it under 7ft for around 200A. Whenever I research on the web I get varying answers but most call for at least 1/0 if not 2/0 wire for this. My question is can I use 2AWG for about 4' of run.
