of 180V. The same set-up using higher voltage modules that result in a 200V maximum power
voltage will result in only 53A. Although 55A to 53A is not a significant change, it does indicate that
a lower input voltage is more productive. Design your system to achieve an ideal input voltage, or a
“sweet spot,” in terms of sufficient Voc for MPPT operations: not too low, not too high. Keep in mind
that an MPPT controller needs to have the open circuit voltage of the array about 33% higher than
the highest battery voltage you plan to charge to.
