The "12V" (18V / 21V see below) output will allow charging of 12V lead acid batteries (car / motorcycle / alarm) and operation of 12V equipment that is tolerant of up to about 18V when loaded and somewhat more under light loads.
Yes it does. It can accept up to a maximum of 100V in solar to charge 12V batteries. To charge 12V batteries it needs Vbat (12V) + 5V to begin charging and the solar must be Vbat +1V to keep charging. Those solar panels Voc are probably more than 24V so you should be fine! Kirby, Good day to you. Thank you for your assurance.
This might sound weird, but both are correct and useful: Nominal 12V voltage is designed based on battery classification. With solar panels, we can charge batteries, and batteries usually have 12V, 24V, or 48V input and output voltage.
