Thanks for explaining all that in detail. Sadly, I (and maybe others, but not as badly most likely :( ) am still in a muddle on some of it--
" 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 what about the battery acceptance rate for a 24v battery? We know the charging profile for a 12v battery and the rates, so eg, with a smart charger starting at 20% charging rate on a 200AH bank of two 100AH in parallel, it would be at 40 amps.
How do you do the AH "size" for the same two batts in series? What is the appropriate charging rate? (comparable to 20% with 12v)
Now what happens with appropriate amps sizes for controllers between 12v and 24v with the same 600w array when on
A. 12v battery bank
B. 24v bank
I also got lost how the "150v input limit" stays the same whether the array is in series or parallel where its voltage and amps changes.
