[QUOTE="Ded Driver, post: 477166, member: 12692"] series might be good for a domestic installation where you could be running a 48V battery bank, but in a car 12V situation the charge controller has input limits. This is a snapshot of my Projecta IDC45 DC-DC charge controller. It can be seen that it has a MAX Input Voltage of 32Vdc (alternator/generator), & a MAX Solar Input of 28Vdc ... so 2 panels in series delivering around 40V exceeds its limit. It will either clip voltage & waste power, or shut off.
