Is 24v Charging the Same as 12v Charging?
With 24v charging on a 24v battery is everything the same as 12s except half the amps? Same charging profile, SOC vs time etc? Is 8.3 amps with 24v the same exactly as 16.6 amps on a 12v bank of the...

Hi,
I think BFL, being a careful man, is more likely to set up switching to easily and quickly change his wiring to the battery bank from 12 to 24 volts for extracting all the amps (since he is allergic to watts) from the solar system. Small loads (up to 20 amps) could be run from a DC to DC converter for under $20. When he wants to use his (expensive) inverters he can switch the bank back to 12 volts, or for small loads up to 150 watts, he can connect the inverter to the dc to dc converter output.
This will allow him to charge with pwm technology and get the same or better power to the bank than an expensive mppt unit.
