50 Amp Receptacle to Inverter
Hello all! Ok, so backstory is I'm doing research on installing a 3000w inverter in my travel trailer, and rather than go through a super complicated and expensive direct to panel wire install, I'm...

Ok, let me see if my understanding makes sense.
At 12 volts, assuming a 3000w inverter, at max load that would be 3000w/12v for a total of 250 amps. However, other than my air conditioner, I believe my 900 watt microwave is the highest load I'd have, which would be 900w/12v for a total of 75 amps. The only other appliances would be the fridge and water heater on gas, my TV and sound bar, lights, and other miscellaneous low power items. Let's say no more than 1500 watts total at any given time for a max amp draw of 125. Might be a low estimate, but that's still over the 100 amp continuous limit for one battery, so I would need a minimum of 2 batteries to spread that load safely.
At 24 volts, the amps are all cut in half. Max amps of 125 under full inverter load, which I don't think I'd ever reach without running the air conditioner, and 63 amps at the more reasonable 1500 watt level.
Since I'd need 2 batteries anyway, it is starting to make sense to do a 24v system. Does this sound right?
