I’ve had both…2012 & 3012 and the 3012 is heads and shoulders above. You are lucky to get 65 amps charging from a 2012 on generator power while my 3012 cranks out 150+ amps.
I don’t understand running AC off of batteries when a generator will do it easily plus charge the batteries. YES it can be done but at some point you have to recharge the batterie’s either with lots of solar $$$ or a generator/alternator.
Using the engine alternator to run a AC that draws 14 amps AC… 170A DC is going to overheat it and the inverter. Anytime I’m using a high amp item, I crank the generator unless quite hours prohibit.
