Hi,
I'm just looking for some advice about exceeding voltage of MPPT controllers. I live in Portugal. Winters are very mild. It rarely ever gets below 0°. I found this coefficient factor spreadsheet that says for -1 to -5 you should calculate 1.12 times your rated Voc. So for me it would be something over 102 Voc. Is that okay, or should I rather connect the panels in parallel and buy more expensive wires.
Thanks
Jan
