asked
4 panels, 2x2 in series, then parallel them, Best configuration?
Please send a photo of the label on the rear of the panel.
Please let us know how cold it gets in middle of winter when the sun is shining where the panels will be.
VOC and temp may force you in one direction, but if 4s & 2s1p are both available options, then shading impacts should also be taken into consideration.
If it is a 12V system, the 100/30 is too small. If it is a 24V system, then 2s2p should work. Use the calculator at: https://www.victronenergy.com/mppt-calculator
