What are you trying to achieve going to 24v?
My reason to jump to 48 volts would be for large wattage inverter use. 3000 watts is right on the edge of a cliff for a 12 volt dc input.
24 volts or (even better) 48 volts makes that much easier.
There is an excellent 48 volt dc air conditioner.
24 volts would save on the cost of the charge controller as many of them can do 24 volts--so they have twice the capacity at 24 than 12 volts.
3000w inverters are commonly run off 12v. I know lots of people who do it...you just need to keep it close to the battery bank. And really if you are going DC on the air/con, not sure why you would need one that big. The next biggest item would typically be a microwave and even the high powered versions are only around 1500w.
Of course I was asking the OP why he was looking at a higher DC voltage. Not many try to run air/con off battery.
