Thanks for the great replies. Looks like I'm setup fine then. I'd like to think I would use the adjustable racks for aiming the panels correctly, but on my last van I had them installed and never once used them, so these are mounted directly up. Should still net me enough power for my needs. Thanks for the help...

#2 - Renewable Energy > Technical Discussion: Other > 4 Kyocera Panels in Series = 80 volts?

I have just installed 4 Kyocera 135w solar panels on my Sprinter van and am curious as to the output from the solar array. The 4 are wired in series. My Outback Flex 60 charge controller is showing as high as 85 volts from the solar array. Is that possible, or is there something wrong? If I understand, these panels are 17 volts, so how can I be getting more than the expected 68 volts? I've double-checked the wiring and am quite certain the series is wired up correctly.

I'm also showing pretty low amps - only up to about 1.5 amps for a total of ~120 watts. It was quite sunny while I was testing (near noon), but the panels aren't aligned to the sun (they face directly up) - this seems low for a 540w system.

Any thoughts or suggestions?

Thanks,
Sam
