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...

Hi,
If you use a pwm controller with a 24 volt panel, essentially you are cutting the solar harvest by around 50%. That makes it a bad deal.
Either find a nominal 12 volt panel (which may often be 17 volts) or use an MPPT controller.
The exception to the above is if you wire the batteries to be 24 volts. But that won't work well with a 24 volt panel--it would need to be about a 30 volt panel.
