High or low voltage for MPPT

kbhale · 12-13-15, 12:07 AM

Hi all I have a question about MPPT charge controller. I recently put together a off grid solar system with battery bank. Just in case the power goes out. The Charge Controller is:
Renogy Tracer 4210 40 Amp MPPT Charge Controller, 12/24V 100VDC Input
I currently have 3 150watt panels wired parallel with 18-19 volts coming into six golf cart batteries, wired for 12volts. Would I be better off wiring the solar panels in series for the higher voltage?
