I only need 12 amps to charge at 120 volts (Lvl 1) , have 800 watts solar and a 2000 watt (Pure Sine Wave) inverter and have tried the recommended 10 AWG cable....it cooked, 7 AWG cable which got over 150 degrees at the battery and inverter connections so tried 5 AWG and it got to 163 degrees same thing all the time the inverter was only pulling 11.47 amps. I have a sneaking suspicion that because it is a 12 volt system that 12 amps at 12 volts is a big part of the problem as the information I have been seeing shows 2 AWG is the wire to use but heat is always going to be a problem.....think I'll just stick with the generator as an alternative.....much less cost and hassle.

Its very clear that you have not done the proper research or used the proper tools (like an ampacity calculator). You are %100 right. For you, just stick with a generator if you aren't willing to do the work for solar.
