MPPT/DC to DC Charger for Trailer Build
Hello all, first time poster. I am currently doing a special purpose conversion of my enclosed gooseneck and am at the point to figure out electricity. I have a lot of 12V equipment, especially str...

Connect the AC/DC converter which should be a 3 stage charger directly to the batteries. Unlikey the alternator of wiring can supply 30A. DC to DC chargers are used for limited battery charging and boosting the voltage.
30A + for lights? Are you using LEDs?
Normal flooded battery discharge is 50% which is 115AH for both. Flooded battery voltage tapers down with discharge. For your application consider 4x GC2s like Trojan at 220AH each for 440AH or 220AH total, or maybe 6x. Lithium batteries are likely much better for your application since they have no voltage sag until about 20% charge left.
Perhaps you should consider a larger gen or 2 in parallel. 2 2000W gens would provide 4000W and perhaps run the A/C at the same time.
