24V battery and mono- or polycristalline panels
● Minimum number of cells in series: 72
(2x 12V panel in series or 1x 24V panel).
● Maximum: 108 cells (3x 12V panel in series).
Note: Note: at low temperatures the open circuit voltage of a
108 cell solar array may exceed 75V, depending on local
conditions and cell specifications. In that case the number of
cells in series must be reduced.
