12v MPPT and 24v MPPT vs 24v PWM Test
Got a chance to try out comparing amps to the battery using MPPT vs PWM on a 24v battery bank and comparing those with the usual MPPT on 12v with my 230w panel. The bank is four 6s, so it was easy ...

My main power use is some 24 v equipment. I also have a 12v house battery.
This discussion has got me wondering: Could I / should I, if doing a 300w solar install, charge the two systems separately, swapping stuff out with Anderson connectors?
This would mean I'd have to get an MPPT controller instead of PWM as I otherwise would, IIUC. Would it be worth the cost? Would it be a pain to switch the controller between 12 and 24 every day?
My camping is generally at about 60-80 degrees F daytime temps, year-round. Now that I know that matters :).
Yipes! That sounds complicated.
Ok the first thing is you don't need MPPT if you have a 24v battery bank, you can run that with your ordinary PWM controller that will do either 24v or 12v.
You can run a split bank with one 24v and the other 12v. There are at least a million (not to exaggerate!) ways of doing all that.
Perhaps if you described your situation/set-up more, we could narrow it down a little. :)
BTW, as the OP I got my hoped for responses, so now it is ok by me to talk about anything else.
