House/solar battery opinions
My current battery space is 20"L x 14"w x 10"H Going solar, and want to packs as much AH in there as I can (reasonably). Currently looking at 250 - 300. Price is not THE deciding factor, unless ...

I find that with usual usage and battery bank etc, etc, morning voltage before solar wake up is in the high 12s. ...
Some other scenario, much contrived wrt real life, could indeed show why you should $pend on MPPT.
You have a 458AH bank, that is why your morning Volts and SOC% are so high and that MPPT has little to add. No real value for you.
I have two banks. 79AH with a 130W panel and 110AH with a 170W array. It is common for me to wake up to 50% SOC where extra current can be harvested. Granted, they will be expen$ive Amps. That is not contrived.
