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...

This will be a single panel system.
The 24 volt panel IMO would be better then a 12 volt panel on the PWM controller I linked to I would assume.
I know from what I read is that hooking up panels in series and an mppt controller is best. So say a guy have 3 24v panels. Hook them in series for 72 volts.
This way you need more volts then the batterys has to charge. So with that set up when the sun just peaks over the horizon say each panel is only producing 5 volts each. The mppt controler will see 15 volts and start charging the batterys.
But I am doing one panel only.
I figure my one 24 volt panel will net similar statistics as above with that renogy PWM 30 amp controller that accepts 48 volts and lower.
Plus the 24 volt panel will compensate for voltage loss through the wiring. Although I will be less then 4 ft from the batterys with the controller. The panels will have a 15 ft tether and be portable that I can move it around in the sun.
Ill do 6 gauge from controller to batterys. From panel to controller I am not sure what size I will use...
