Who has Solar/ what controller/panels?
I read about MPPT vs PWM.. OK I understand.. But cost wise and from what I read here on this site, is a 250watt 24V panel from solar blvd and a PWM 30 amp controller is a cheap option. $170 fo...

If you use a PWM controller the absolute max amps you will get will be the max amps (Isc) listed on the panel specs. PWM can not generate more amps than the panel provides. That is the primary reason they are less expensive than MPPT controllers.
The max amps are probably 8 or 9 amps for a 250W 24V panel that you are looking at.
So with a PWM controller for a 250W 24V panel, you will be able to get about 126 Watts maximum (9 Amps X 14 Volts) while charging your batteries.
However, you will get "your max charging rate" for a longer number of hours because you will have an oversized panel which will get you more amps during hours when the sun is not so high in the sky.
