Used Solar Panels 100 for Anker 767, please help

Can you please check my calculations to see if 6 used TopSolar flexible 100 watt panels will work with the Anker 767?

According to Anker:
"Any 11-60V solar panel with an XT-60 female connector can charge the 767 Power Station; If you use an 11-32V solar panel, the current supports 10A max. When you use a 32-60V solar panel, the current supports 20A max. We recommend using Anker 531 Solar Panels (200W) for the best compatibility."

I found 6 used flexible panels, some have damage...I'm going to check them with a multimeter before buying.

TopPower by Gree Sonic
Open circuit voltage (VOC) 20.77 v
Short circuit current (Isc) 6.25 amps
Voltage at Pmax (Vmp) 17.6V
Current at Pmax (Imp) 5.69 amps

With the 60 V at 20 amp max, would 3s2p damage the anker 767? 3s2p ((20.77V)*3)= 62.31 if I'm using Open circuit voltage. (VOC).
((5.69amp)*2)= 11.30 amps.

Is this math correct? And if so, would the voltage reach that high if the panels are slightly damaged?

Thanks for your help

Yes, you need to use Voc. Voltage limit is a do not exceed spec. You are already over even before accounting for cold temperatures increasing the voltage.

You can consider 2s3p which should stay under the specs however you need to add fuses unless each of your panels can handle the Isc of a fault

Thanks for the feedback. I thought about 2s3p, but I thought maybe under 60 V it would only allow 20 amps. Now that I checked the instructions again, it says 32v-60v would allow max 20amp. So I think the 2s3p setup will work perfectly. Thank you again.
 
I'm in the same boat with the anchor 767 and 6 Renegy 100 W panels. I was going to do the same thing by wiring three and series and then paralleling them together. The voltage comes over around 4 and 1/2 so that won't work. My question is guys is I really need your help because in this thread you say 2s 3p which I know what that is but I just can't wrap my brain around it. I come up with five panels from the 2s3p but I have six. Can y'all please elaborate more and possibly give a diagram on how to do that configuration? My mind is stuck on the original configuration and for some reason I cannot picture what 2s3p looks like and the connections I need to make. If you're laughing I understand but I'm really trying to make this work. It's just aggravating that anchor limited it to 60 volts when there are other machines out there at the same power that have 150 volt controller. Thanks in advance. Wouldn't to ask 3p only be five panels? This is just got me really confused please help me. Guys I keep editing this cuz I'm hoping to figure it out. The second photo that I got from renogy would that be a four parallel 2 Series setup? If that's the case I would just knock one pair of panels off correct and if I did just to help me out what would be my voltage in my amperage from the spec picture of my panels? Thanks again. The last picture is a rough draft but please check behind me. I think I have it figured out.
