PV configuration

I have 10 (205 W) Kyocera PVs with the following parameters

Maximum Power               205W
Maximum System Voltage      1000V
Maximum Power Voltage       26.6V
Maximum Power Current       7.71A
Open Circuit Voltage (VOC)  33.2V
Short Circuit Current (ISC) 8.36A

I also have a FM-80 Outback FLEXmax Charge controller? I have a 24 VDC system. What would be the optimum configuration ( series/parallel) of the PVs ?

Re: PV configuration


 to use all 10 pv modules it looks like 5 strings of 2 at 52 volts.* with the fm-80 for a 24vdc nominal system. we are right on (over) the max output for that 80amp controller

 48vdc would be nice but we may not get enough output from those modules.

*(5 parallel strings, each made up of 2 modules in series)

good luck

edit: we may end up with a better system just using 9 modules in 3 strings of 3 at 78vdc and a 48vdc nominal setup.
