I might have just seen it there for a minute!
I am using the same size battery bank in each case, but you are increasing it each time so it can still take the same amps at the higher voltage.
When you say 24v bank, you just forgot to say you need more batteries :) to keep accepting that 45amps. No, you said never mind battery acceptance rates, you are powering loads.
"..... everything is the same except the battery voltage is 48 as compared to 12 allowing the array max power (45 amp controller) to be (45 amps X 48 Volts = 2,160 watts) with the same max inout voltage limitation of 150 VDC – the controller will then be able to put 45 amps (it's 45 amp rating) into the 48 volt battery bank."
I am still stuck here. You jacked up the size of the array so it has more total Voc? so how can that 150v input limit still work?
" A 45 amp controller could have up to a (45amps X 24 volts = 1080 watt array) and then supply 45 amps to the 24 volt battery. "
But the 24v "battery" is half the AH of the 12v battery as when you have two 12s in series vs parallel, so it can only take half the amps.
which is where I got lost, but now I am found. :) You just need to double the number of 100AH batteries :)
